WebHuman phospholipid scramblases (hPLSCRs) are a family of four homologous single pass transmembrane proteins (hPLSCR1-4) initially identified as the proteins responsible for Ca2+mediated bidirectional phospholipid translocation in plasma membrane. WebPhospholipid Scramblase 1, an interferon-regulated gene located at 3q23, is regulated by SnoN/SkiL in ovarian cancer cells. The C-terminal helix of human PLSCR1 is required for membrane insertion and calcium binding. Phospholipid scramblase 1 expression is enhanced in patients with antiphospholipid syndrome.
