Protein Name:
Oxysterol-binding protein-related protein 9
|
UniprotKB/SwissProt ID: Q96SU4 (Q96SU4)
Gene Name:
OSBPL9
Organism: Homo sapiens (Human)
Function: Interacts with OSBPL11 to function as lipid transfer proteins (PubMed:39106189). Together they form a heterodimer that localizes at the ER-trans-Golgi membrane contact sites, and exchanges phosphatidylserine (1,2-diacyl-sn-glycero-3-phospho-L-serine, PS) for phosphatidylinositol-4-phosphate (1,2-diacyl-sn-glycero-3-phospho-(1D-myo-inositol 4-phosphate), PI(4)P) between the two organelles, a step that is critical for sphingomyelin synthesis in the Golgi complex (PubMed:39106189)
