OSBPL2 - oxysterol binding protein like 2 Gene
Also Known as ORP2; ORP-2; DFNA67; DNFA67
Species: Homo sapiens
About OSBPL2
This gene has 28 transcripts (splice variants), 272 orthologues, 11 paralogues and is associated with 2 phenotypes. Ubiquitous expression in skin (RPKM 12.0), esophagus (RPKM 9.6) and 25 other tissues.
Summary
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, although the encoded protein contains only the sterol-binding domain. In vitro studies have shown that the encoded protein can bind strongly to phosphatic acid and weakly to phosphatidylinositol 3-phosphate, but cannot bind to 25-hydroxycholesterol. The protein associates with the Golgi apparatus. Transcript variants encoding different isoforms have been described. [provided by RefSeq, Sep 2014]
