Function: Plays a role in phagocytosis by macrophages of apoptotic cells. Binds APOA1 and may function in apolipoprotein-mediated phospholipid efflux from cells. May also mediate cholesterol efflux. May regulate cellular ceramide homeostasis during keratinocytes differentiation.
Cellular location: Cell membrane; Multi-pass membrane protein. Golgi apparatus membrane; Multi-pass membrane protein. Endosome membrane; Multi-pass membrane protein. Note=Localizes to cell membrane ruffles and phagocytic cups of macrophages stimulated with C1q or apoptotic cells. Localizes to the cytoplasm of resting macrophages, probably in Golgi and endosomes. Localizes to the apical brush border of cells in the proximal tubules of kidney. Isoform 2 may localize to the endoplasmic reticulum.
Tissue specificity: Expressed in leukocytes (at protein level). Widely expressed. Highly expressed in myelo-lymphatic tissues including peripheral leukocytes, thymus, spleen and bone marrow. Isoform 2 is more abundant in lymph node, spleen, thymus and trachea than isoform 1 which is more strongly expressed in brain and bone marrow.
