Recombinant Human Membrane-associated phosphatidylinositol transfer protein 1 (PITPNM1), Truncated

Uniprot Id

O00562

Target Species

Human

Target Name

PITPNM1

Target Full Name

Membrane-associated phosphatidylinositol transfer protein 1

Target Function

Catalyzes the transfer of phosphatidylinositol (PI) between membranes. Binds PI, phosphatidylcholine (PC) and phosphatidic acid (PA) with the binding affinity order of PI > PA > PC. Regulates RHOA activity, and plays a role in cytoskeleton remodeling. Necessary for normal completion of cytokinesis. Plays a role in maintaining normal diacylglycerol levels in the Golgi apparatus. Necessary for maintaining the normal structure of the endoplasmic reticulum and the Golgi apparatus. Required for protein export from the endoplasmic reticulum and the Golgi. Binds calcium ions.

Target Subcellular Location

Target Background

PITPNM1 belongs to a family of membrane-associated phosphatidylinositol transfer domain-containing proteins that share homology with the Drosophila retinal degeneration B (rdgB) protein (Ocaka et al., 2005 [PubMed 15627748]).
