Gene names: PRKACB
Protein names and data: KAPCB_HUMAN , cAMP-dependent protein kinase catalytic subunit beta; PKA C-beta; 2.7.11.11 Lenght: 351 a.a.
Mass: 40623 Da
fasta formatted sequence
Function: Mediates cAMP-dependent signaling triggered by receptor binding to GPCRs. PKA activation regulates diverse cellular processes such as cell proliferation, the cell cycle, differentiation and regulation of microtubule dynamics, chromatin condensation and decondensation, nuclear envelope disassembly and reassembly, as well as regulation of intracellular transport mechanisms and ion flux. Regulates the abundance of compartmentalized pools of its regulatory subunits through phosphorylation of PJA2 which binds and ubiquitinates these subunits, leading to their subsequent proteolysis.
Catalytic activity: ATP + a protein = ADP + a phosphoprotein.
Cellular location: Cytoplasm. Cell membrane. Nucleus (By similarity). Note=Translocates into the nucleus (monomeric catalytic subunit) (By similarity). The inactive holoenzyme is found in the cytoplasm (By similarity).
Tissue specificity: Isoform 1 is most abundant in the brain, with low level expression in kidney. Isoform 2 is predominantly expressed in thymus, spleen and kidney. Isoform 3 and isoform 4 are only expressed in the brain.
