Membrane-associated phosphatidylinositol transfer protein 1 is a protein that in humans is encoded by the PITPNM1 gene.

Function

PITPNM1 belongs to a family of proteins that share homology with the Drosophila retinal degeneration B (rdgB) protein.[supplied by OMIM]

Interactions

PITPNM1 has been shown to interact with PTK2B.
