CC -!- FUNCTION: Myosins are actin-based motor molecules with ATPase
CC activity. Unconventional myosins serve in intracellular movements.
CC Their highly divergent tails are presumed to bind to membranous
CC compartments, which would be moved relative to actin filaments.
CC Involved in glucose transporter recycling in response to insulin
CC by regulating movement of intracellular GLUT4-containing vesicles
CC to the plasma membrane. Component of the hair cell's (the sensory
CC cells of the inner ear) adaptation-motor complex. Acts as a
CC mediator of adaptation of mechanoelectrical transduction in
CC stereocilia of vestibular hair cells. Binds phosphoinositides and
CC links the actin cytoskeleton to cellular membranes (By
CC similarity).
CC -!- FUNCTION: Isoform 3 is involved in regulation of transcription.
CC Associated with transcriptional active ribosomal genes. Appears to
CC cooperate with the WICH chromatin-remodeling complex to facilitate
CC transcription. Necessary for the formation of the first
CC phosphodiester bond during transcription initiation (By
CC similarity).
CC -!- SUBUNIT: Interacts (via its IQ motifs) with calmodulin. Interacts
CC (via its IQ motifs) with CABP1 and CIB1; the interaction with
CC CABP1 and CIB1 is calcium-dependent. Interacts (via tail domain)
CC with PLEKHB1 (via PH domain); the interaction is not affected by
CC the presence or absence of calcium and calmodulin. Interacts with
CC POLR1A and POLR2A. Component of the B-WICH complex, at least
CC composed of SMARCA5/SNF2H, BAZ1B/WSTF, SF3B1, DEK, MYO1C, ERCC6,
CC MYBBP1A and DDX21 (By similarity). Interacts with RPS6 and actin.
CC -!- SUBCELLULAR LOCATION: Isoform 1: Cytoplasm. Nucleus.
CC Note=Colocalizes with RNA polymerase II. Absent from nucleoli and
CC does not colocalize with RNA polymerase I. Translocates to nuclear
CC speckles upon exposure to inhibitors of RNA polymerase II
CC transcription.
CC -!- SUBCELLULAR LOCATION: Isoform 2: Cytoplasm. Cell membrane (By
CC similarity). Cell projection, stereocilium membrane (By
CC similarity). Note=Colocalizes with CABP1 and CIB1 at cell margin,
CC membrane ruffles and punctate regions on the cell membrane.
CC Colocalizes in adipocytes with GLUT4 in actin-based membranes.
CC Localizes transiently at cell membrane to region known to be
CC enriched in PIP2. Activation of phospholipase C results in its
CC redistribution to the cytoplasm (By similarity).
CC -!- SUBCELLULAR LOCATION: Isoform 3: Nucleus, nucleoplasm. Nucleus,
CC nucleolus. Nucleus, nuclear pore complex. Note=Colocalizes with
CC RNA polymerase II in the nucleus. Colocalizes with RNA polymerase
CC I in nucleoli (By similarity). In the nucleolus, is localized
CC predominantly in dense fibrillar component (DFC) and in granular
CC component (GC). Accumulates strongly in DFC and GC during
CC activation of transcription. Colocalizes with transcription sites.
CC Colocalizes in the granular cortex at the periphery of the
CC nucleolus with RPS6. Colocalizes in nucleoplasm with RPS6 and
CC actin that are in contact with RNP particles. Colocalizes with
CC RPS6 at the nuclear pore level.

CC Event=Alternative splicing; Named isoforms=3;
CC Name=1; Synonyms=A;
CC IsoId=O00159-1; Sequence=Displayed;
CC Name=2; Synonyms=C;
CC IsoId=O00159-2; Sequence=VSP_036861;
CC Note=Contains a N-acetylmethionine at position 1;
CC Name=3; Synonyms=B, Nuclear myosin 1, NM1, NMI;
CC IsoId=O00159-3; Sequence=VSP_036862;
CC -!- DOMAIN: Binds directly to large unilamellar vesicles (LUVs)
CC containing phosphatidylinositol 4,5-bisphosphate (PIP2) or
CC inositol 1,4,5-trisphosphate (InsP3). The PIP2-binding site
CC corresponds to a putative PH domain present in its tail domain (By
CC similarity).
CC -!- PTM: Isoform 2 contains a N-acetylmethionine at position 1.
CC -!- SIMILARITY: Contains 2 IQ domains.
CC -!- SIMILARITY: Contains 1 myosin head-like domain.
CC -!- CAUTION: Represents a unconventional myosin. This protein should
CC not be confused with the conventional myosin-1 (MYH1).

CC -!- FUNCTION: Myosins are actin-based motor molecules with ATPase
CC activity. Unconventional myosins serve in intracellular movements.
CC Their highly divergent tails are presumed to bind to membranous
CC compartments, which would be moved relative to actin filaments.
CC Involved in glucose transporter recycling in response to insulin
CC by regulating movement of intracellular GLUT4-containing vesicles
CC to the plasma membrane. Component of the hair cell's (the sensory
CC cells of the inner ear) adaptation-motor complex. Acts as a
CC mediator of adaptation of mechanoelectrical transduction in
CC stereocilia of vestibular hair cells. Binds phosphoinositides and
CC links the actin cytoskeleton to cellular membranes (By
CC similarity).
CC -!- FUNCTION: Isoform 3 is involved in regulation of transcription.
CC Associated with transcriptional active ribosomal genes. Appears to
CC cooperate with the WICH chromatin-remodeling complex to facilitate
CC transcription. Necessary for the formation of the first
CC phosphodiester bond during transcription initiation (By
CC similarity).
CC -!- SUBUNIT: Interacts (via its IQ motifs) with calmodulin. Interacts
CC (via its IQ motifs) with CABP1 and CIB1; the interaction with
CC CABP1 and CIB1 is calcium-dependent. Interacts (via tail domain)
CC with PLEKHB1 (via PH domain); the interaction is not affected by
CC the presence or absence of calcium and calmodulin. Interacts with
CC POLR1A and POLR2A. Component of the B-WICH complex, at least
CC composed of SMARCA5/SNF2H, BAZ1B/WSTF, SF3B1, DEK, MYO1C, ERCC6,
CC MYBBP1A and DDX21 (By similarity). Interacts with RPS6 and actin.
CC -!- SUBCELLULAR LOCATION: Isoform 1: Cytoplasm. Nucleus.
CC Note=Colocalizes with RNA polymerase II. Absent from nucleoli and
CC does not colocalize with RNA polymerase I. Translocates to nuclear
CC speckles upon exposure to inhibitors of RNA polymerase II
CC transcription.
CC -!- SUBCELLULAR LOCATION: Isoform 2: Cytoplasm. Cell membrane (By
CC similarity). Cell projection, stereocilium membrane (By
CC similarity). Note=Colocalizes with CABP1 and CIB1 at cell margin,
CC membrane ruffles and punctate regions on the cell membrane.
CC Colocalizes in adipocytes with GLUT4 in actin-based membranes.
CC Localizes transiently at cell membrane to region known to be
CC enriched in PIP2. Activation of phospholipase C results in its
CC redistribution to the cytoplasm (By similarity).
CC -!- SUBCELLULAR LOCATION: Isoform 3: Nucleus, nucleoplasm. Nucleus,
CC nucleolus. Nucleus, nuclear pore complex. Note=Colocalizes with
CC RNA polymerase II in the nucleus. Colocalizes with RNA polymerase
CC I in nucleoli (By similarity). In the nucleolus, is localized
CC predominantly in dense fibrillar component (DFC) and in granular
CC component (GC). Accumulates strongly in DFC and GC during
CC activation of transcription. Colocalizes with transcription sites.
CC Colocalizes in the granular cortex at the periphery of the
CC nucleolus with RPS6. Colocalizes in nucleoplasm with RPS6 and
CC actin that are in contact with RNP particles. Colocalizes with
CC RPS6 at the nuclear pore level.

CC Event=Alternative splicing; Named isoforms=3;
CC Name=1; Synonyms=A;
CC IsoId=O00159-1; Sequence=Displayed;
CC Name=2; Synonyms=C;
CC IsoId=O00159-2; Sequence=VSP_036861;
CC Note=Contains a N-acetylmethionine at position 1;
CC Name=3; Synonyms=B, Nuclear myosin 1, NM1, NMI;
CC IsoId=O00159-3; Sequence=VSP_036862;
CC -!- DOMAIN: Binds directly to large unilamellar vesicles (LUVs)
CC containing phosphatidylinositol 4,5-bisphosphate (PIP2) or
CC inositol 1,4,5-trisphosphate (InsP3). The PIP2-binding site
CC corresponds to a putative PH domain present in its tail domain (By
CC similarity).
CC -!- PTM: Isoform 2 contains a N-acetylmethionine at position 1.
CC -!- SIMILARITY: Contains 2 IQ domains.
CC -!- SIMILARITY: Contains 1 myosin head-like domain.
CC -!- CAUTION: Represents a unconventional myosin. This protein should
CC not be confused with the conventional myosin-1 (MYH1).
CC -!- SEQUENCE CAUTION:

Myosins are molecular motors that, upon interaction with actin
filaments, utilize energy from ATP hydrolysis to generate mechanical
force. For further background information on myosins, see MYO1A
(601478).
CLONING
By screening a kidney cDNA library with a mouse Myo1c probe, Crozet et
al. (1997) obtained a human cDNA encoding MYO1C. The deduced 1,028-amino
acid protein, which is 96% identical to the mouse protein, contains ATP-
and actin-binding sequences in the motor (or head) domain, followed by
three 23-residue IQ motifs and a tail domain rich in basic residues that
is expected to interact with negatively charged membrane phospholipids.
Northern blot analysis revealed ubiquitous expression of Myo1c in adult
mouse tissues.
GENE FUNCTION
MYO1C, also known as myosin I-beta and MYR2, was thought to mediate the
slow component of adaptation by hair cells, the sensory cells of the
inner ear. To test this hypothesis, Holt et al. (2002) mutated tyr61 of
MYO1C to gly, conferring susceptibility to inhibition by N6-modified ADP
analogs. They expressed the mutant MYO1C in utricular hair cells of
transgenic mice, delivered an ADP analog through a whole-cell recording
pipette, and found that the analog rapidly blocked adaptation to
positive and negative deflections in transgenic cells but not in
wildtype cells. The speed and specificity of inhibition suggested that
MYO1C participates in adaptation in hair cells.
Bose et al. (2002) reported that the unconventional myosin MYO1C is
present in GLUT4 (138190)-containing vesicles purified from 3T3-L1
adipocytes. MYO1C is highly expressed in primary and cultured
adipocytes. Insulin (176730) enhances the localization of MYO1C with
GLUT4 in cortical tubulovesicular structures associated with actin
filaments, and this colocalization is insensitive to wortmannin.
Insulin-stimulated translocation of GLUT4 to the adipocyte plasma
membrane is augmented by the expression of wildtype MYO1C and inhibited
by a dominant-negative cargo domain of MYO1C. A decrease in the
expression of endogenous MYO1C mediated by small interfering RNAs
inhibited insulin-stimulated uptake of 2-deoxyglucose. Thus, Bose et al.
(2002) concluded that MYO1C functions in a
phosphatidylinositol-3-hydroxykinase (PI3K; see 601232)-independent
insulin signaling pathway that controls the movement of intracellular
GLUT4-containing vesicles to the plasma membrane.
MAPPING
Using PCR and radiation hybrid analysis, Crozet et al. (1997) mapped the
MYO1C gene to 17p13.
HISTORY
A report by Nunez et al. (2008) indicating that 3-dimensional
motor-dependent interchromosomal interactions involving MYO1C are
required to achieve enhanced transcription of specific estrogen-receptor
target genes was retracted.
