About OSBPL8

Cytogenetic location: 12q21.2 Genomic coordinates (GRCh38): 12:76,351,797-76,559,771 (from NCBI)

This gene has 18 transcripts (splice variants), 214 orthologues and 11 paralogues. Ubiquitous expression in kidney (RPKM 16.1), lymph node (RPKM 15.4) and 25 other tissues.

Summary

This gene encodes a member of a family of proteins containing an N-terminal pleckstrin homology domain and a highly conserved C-terminal oxysterol-binding protein-like sterol-binding domain. It binds mutliple lipid-containing molecules, including phosphatidylserine, phosphatidylinositol 4-phosphate (PI4P) and oxysterol, and promotes their exchange between the endoplasmic reticulum and the plasma membrane. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2016]
