STARD10, STAR-related lipid transfer protein 10 or PCTP-like (33 kDa) is a transporter for lipids which specifically shuttles phosphatidylcholine and phosphatidylethanolamine between membranes. Mammalian STARD10 belongs to a family of fifteen START-domain proteins. In these family members, the carboxy terminal START-domain is conserved and functions in lipid binding or as a lipid sensing domain. The specificity for the type of lipid bound differs among family members (e.g., STARD1,3,5 binds Cholesterol, STARD5 binds 25-hydroxycholesterol, STARD2 binds phosphatidylcholine, and STARD11 binds ceramides). STARD proteins have been associated with various cellular processes such as lipid trafficking, lipid metabolism, and cell signaling (1, 2).
STARD10 is broadly expressed in different organs and tissues such as the brain, endocrine tissues, liver, and gastrointestinal tract. STARD10 is regulated by Casein kinase II, which phosphorylates STARD10 at serine 284 leading to decreased lipid transfer activity and reduced membrane association. STARD10 is overexpressed in breast carcinoma cell lines and in primary breast cancers (3). STARD10 has been implicated in the regulation of bile acid homeostasis and more recently in the regulation of insulin secretion from beta-cells (1, 2, 4).
