DESCRIPTION

Also known as OSH6_YEAST, OSH6. Lipid 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 phosphatase in the endoplasmic reticulum (PubMed:23934110, PubMed:26206936). Binds phosphatidylserine and PI4P in a mutually exclusive manner (PubMed:26206936).
