UniprotKB/SwissProt ID: Q91V24 (Q91V24)
Gene Name:
Abca7
Organism: Mus musculus (Mouse)
Function: Probable ATP-binding cassette (ABC) transporter that plays a role in lipid homeostasis and macrophage-mediated phagocytosis (PubMed:12917409, PubMed:15550377, PubMed:16908670, PubMed:20495215, PubMed:27030769, PubMed:27472885). Binds APOA1 and may function in apolipoprotein-mediated phospholipid efflux from cells (PubMed:12917409). May also mediate cholesterol efflux (By similarity). May regulate cellular ceramide homeostasis during keratinocyte differentiation (By similarity). Involved in lipid raft organization and CD1D localization on thymocytes and antigen-presenting cells, which plays an important role in natural killer T-cell development and activation (PubMed:28091533). Plays a role in phagocytosis of apoptotic cells by macrophages (PubMed:16908670). Macrophage phagocytosis is stimulated by APOA1 or APOA2, probably by stabilization of ABCA7 (PubMed:20495215). Also involved in phagocytic clearance of amyloid-beta by microglia cells and macrophages (PubMed:27472885). Further limits amyloid-beta production by playing a role in the regulation of amyloid-beta A4 precursor protein (APP) endocytosis and/or processing (PubMed:26260791, PubMed:27030769)
