Protein Name:
Membrane-associated phosphatidylinositol transfer protein 1
|
UniprotKB/SwissProt ID: Q5U2N3 (Q5U2N3)
Gene Name:
Pitpnm1
Organism: Rattus norvegicus (Rat)
Function: Catalyzes the transfer of phosphatidylinositol (PI) between membranes (By similarity). Binds PI, phosphatidylcholine (PC) and phosphatidic acid (PA) with the binding affinity order of PI > PA > PC (By similarity). Regulates RHOA activity, and plays a role in cytoskeleton remodeling (By similarity). Necessary for normal completion of cytokinesis (By similarity). Plays a role in maintaining normal diacylglycerol levels in the Golgi apparatus (By similarity). Necessary for maintaining the normal structure of the endoplasmic reticulum and the Golgi apparatus (By similarity). Required for protein export from the endoplasmic reticulum and the Golgi (By similarity). Binds calcium ions (By similarity)
