Oxysterol-binding protein-related protein 3 is a protein that in humans is encoded by the OSBPL3 gene.

Function

This gene encodes a member of the oxysterol-binding protein (OSBP) family, a group of intracellular lipid receptors. Most members contain an N-terminal pleckstrin homology domain and a highly conserved C-terminal OSBP-like sterol-binding domain. Several transcript variants encoding different isoforms have been identified.
