UniProtKB - C8ZI10 (RSB1_YEAS8)
Protein
Sphingoid long-chain base transporter RSB1
Gene
RSB1
Organism
Saccharomyces cerevisiae (strain Lalvin EC1118 / Prise de mousse) (Baker's yeast)
Status
Functioni
Catalyzes the ATP-dependent translocation of sphingoid long-chain bases (LCBs) from the cytoplasmic site toward the extracytoplasmic side of the membrane (flip-flop). Involved in the establishment of the functional lipid asymmetry of the plasma membrane. Regulates intracellular levels of LCBs, sphingolipid precursors that are growth inhibitory at increased levels (By similarity).
