Summary: This gene encodes a member of the oxysterol-binding protein (OSBP) family, a group of intracellular lipid receptors that play a key role in the maintenance of cholesterol balance in the body. Most members contain an N-terminal pleckstrin homology domain and a highly conserved C-terminal OSBP-like sterol-binding domain. This gene has been shown to be imprinted, with preferential expression from the maternal allele only in placenta. Transcript variants encoding different isoforms have been identified.

ORP5 promotes migration and invasion of cervical cancer cells by inhibiting endoplasmic reticulum stress.
Title: ORP5 promotes migration and invasion of cervical cancer cells by inhibiting endoplasmic reticulum stress.
ORP5 and ORP8: Sterol Sensors and Phospholipid Transfer Proteins at Membrane Contact Sites?
Title: ORP5 and ORP8: Sterol Sensors and Phospholipid Transfer Proteins at Membrane Contact Sites?
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.
Data suggest that ORP5/OSBPL5 promotes cell proliferation, cell motility, and invasiveness of neoplasm cells; this effect of ORP5/OSBPL5 depends on functional OSBP-related domain (ORD). ORP5/OSBPL5 is needed for activation of mTORC1 signaling and for transport of mTOR to lysosomes. (mTORC1 = mechanistic target of rapamycin complex-1; mTOR = mechanistic target of rapamycin)
Title: Oxysterol-binding protein-related protein 5 (ORP5) promotes cell proliferation by activation of mTORC1 signaling.
ORP5/8 regulate Ca(2+) signaling at specific membrane contact sites foci.
Title: Oxysterol-binding protein related-proteins (ORPs) 5 and 8 regulate calcium signaling at specific cell compartments.
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.
Title: ORP5 and ORP8 bind phosphatidylinositol-4, 5-biphosphate (PtdIns(4,5)P (2)) and regulate its level at the plasma membrane.
mammalian ORP5 and ORP8 proteins localize to ER-mitochondrial MCS, in addition to ER-PM contact sites.
Title: ORP5/ORP8 localize to endoplasmic reticulum-mitochondria contacts and are involved in mitochondrial function.
Results show that OSBPL5 and CALU were expressed at higher levels in the lung tissues of metastasis-positive cases than that in the metastasis-negative cases suggesting they can promote invasiveness of lung cancer cells.
Title: Identification and evaluation of metastasis-related proteins, oxysterol binding protein-like 5 and calumenin, in lung tumors.
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.
ORP5 may cooperate with NPC1 to mediate the exit of cholesterol from endosomes/lysosomes.
Title: A role for oxysterol-binding protein-related protein 5 in endosomal cholesterol trafficking.

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.
