Protein Information (annotations from UniProt)

Database IDHIV0002059
UniProt IDQ9H0X9
Primary gene name(s)OSBPL5
Synonym gene name(s)KIAA1534, OBPH1, ORP5
Protein nameOxysterol-binding protein-related protein 5
Protein functionLipid transporter involved in lipid countertransport between the endoplasmic reticulum and the plasma membrane: specifically exchanges phosphatidylserine with phosphatidylinositol 4-phosphate, PI4P, delivering phosphatidylserine to the plasma membrane in exchange for PI4P, which is degraded by the SAC1/SACM1L phosphatase in the endoplasmic reticulum. Binds phosphatidylserine and PI4P in a mutually exclusive manner, PubMed:23934110, PubMed:26206935. May cooperate with NPC1 to mediate the exit of cholesterol from endosomes/lysosomes, PubMed:21220512. Binds 25-hydroxycholesterol and cholesterol, PubMed:17428193. {ECO:0000269|PubMed:17428193, ECO:0000269|PubMed:21220512, ECO:0000269|PubMed:23934110, ECO:0000269|PubMed:26206935}.
Subcellular locationEndoplasmic reticulum membrane {ECO:0000269|PubMed:21220512, ECO:0000269|PubMed:26206935};
Single-pass membrane protein {ECO:0000269|PubMed:21220512}. Note=Localizes to the cortical endoplasmic reticulum at the endoplasmic reticulum-plasma membrane contact sites. {ECO:0000269|PubMed:26206935}.
