PLSCR1 polyclonal antibody

Phospholipid scramblase 1 (PLSCR1) is 1 of 4 scramblases encoded in the human genome. Phospholipid scramblases function to catalyze calcium-mediated ATP-independent mobilization of phospholipids between the inner and outer leaflet of plasma membrane in activated, injured, or apoptotic cells. PLSCR1 is a type-II transmembrane protein with a short 9 amino acid C-terminal domain and a long N-terminal extracellular domain. Although PLSCR1 is part of a family of proteins that function to catalyze phospholipid mobilization, PLSCR1 may have alternative functions. Rather, PLSCR1 may function to activate cell signaling pathways, particularly in phagocytic cells of monocyte/macrophage lineage. Microglia, resident macrophages of the brain, play a key role in clearance of cellular and pathologic debris where altered phagocytosis may contribute to neurodegenerative diseases like Alzheimer’s disease. PLSCR1 may regulate microglia phagocytosis, representing a potential therapeutic target to modulate microglia phagocytosis.
