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]

ORP8 induces apoptosis by releasing cytochrome c from mitochondria in nonsmall cell lung cancer.
Title: ORP8 induces apoptosis by releasing cytochrome c from mitochondria in non‑small cell lung cancer.
ORP5/8 recruitment to the plasma membrane occurs through interactions with the N-terminal Pleckstrin homology domains and adjacent basic residues of ORP5/8 with both phosphatidylinositol 4-phosphate and Phosphatidylinositol 4,5-bisphosphate.
Title: PI(4,5)P(2) controls plasma membrane PI4P and PS levels via ORP5/8 recruitment to ER-PM contact sites.

Title: Both the PH domain and N-terminal region of oxysterol-binding protein related protein 8S are required for localization to PM-ER contact sites.
ORP5/8 are endoplasmic reticulum (ER) membrane proteins implicated in lipid trafficking that localize to ER-plasma membrane (PM) contacts and maintain membrane homeostasis. Here the authors show that PtdIns(4,5)P 2 plays a critical role in the targeting and function of ORP5/8 at the PM.

we found that overexpression of ORP8 significantly inhibits GC cell proliferation and implanted tumor growth in vivo. Induction of ER stress, inhibition of Wnt signaling, and apoptotic cell death are involved in ORP8-induced inhibition of GC cell proliferation.

ORP5 and ORP8 could mediate PI4P/phosphatidylserine (PS) countertransport between the endoplasmic reticulum (ER) and the plasma membrane (PM), thus delivering PI4P to the ER-localized PI4P phosphatase Sac1 for degradation and PS from the ER to the PM.
Title: INTRACELLULAR TRANSPORT. PI4P/phosphatidylserine countertransport at ORP5- and ORP8-mediated ER-plasma membrane contacts.
role of ORP8 in Fas translocation to the plasma membrane and its down-regulation by miR-143 offer a putative mechanistic explanation for HCC resistance to apoptosis

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
