scrm-1 encodes, by alternative splicing, two isoforms of a putativephospholipid scramblase required for phosphatidylserine exposure and thenormally rapid engulfment of apoptotic cells in the germline; SCRM-1 islocalized to plasma membranes of embryonic cells from earlyembryogenesis onward; SCRM-1 is specifically bound by residues 380-550of WAH-1 in vitro, and WAH-1 binding is required in liposomes for morethan residual SCRM-1 activity; in scrm-1(tm698) or scrm-1(tm805)embryos, apoptotic cells do eventually disappear, but their removal isdelayed; SCRM-1 is homologous to human PLSCR1-5, and paralogous toSCRM-2 through SCRM-8.
Enables phospholipid scramblase activity. Involved in phosphatidylserine exposure on apoptotic cell surface. Located in plasma membrane. Expressed in several structures, including germ line. Is an ortholog of several human genes including PLSCR2 (phospholipid scramblase 2); PLSCR3 (phospholipid scramblase 3); and PLSCR4 (phospholipid scramblase 4).
Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
