UniprotKB/SwissProt ID: A2A8Z1 (A2A8Z1)
Gene Name:
Osbpl9
Organism: Mus musculus (Mouse)
Function: Interacts with OSBPL11 to function as lipid transfer proteins. 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
Other Modifications: View all modification sites in dbPTM
Protein Subcellular Localization: Late endosome membrane. Golgi apparatus, trans-Golgi network membrane
