Anti-Rt PLSCR1 Ascites Monoclonal Antibody

PLSCR1 (phospholipid scramblase 1) is a multiply palmitoylated endofacial plasma membrane protein containing several SH3 and WW domain binding motives. In the plasma membrane, PLSCR1 plays a role in transbilayer lipid redistributions and signal transduction. Nonpalmitoylated PLSCR1, however, is able to be transported into the nucleus and bind DNA. PLSCR1 potentiates the antiviral activity of interferon and its expression is highly induced by interferons and growth factors.

Pooled lipid raft fraction isolated from RBL-2H3 cells. The antibody 13A6 [TEC-23] binds to an intracellular epitope of rat Phospholipid Scramblase 1 (PLSCR1), an 37-49 kDa protein, accelerating bidirectional movement of plasma membrane phospholipids under conditions of elevated calcium.

May mediate accelerated ATP-independent bidirectional transbilayer migration of phospholipids upon binding calcium ions that results in a loss of phospholipid asymmetry in the plasma membrane. May play a central role in the initiation of fibrin clot formation, in the activation of mast cells and in the recognition of apoptotic and injured cells by the reticuloendothelial system.
