- Background
- StAR-related lipid transfer protein 10 (STARD10) or PCTP-like protein is a lipid transfer protein that in humans is encoded by the STARD10 gene. StarD10 is a dual-specificity lipid transfer protein capable of shuttling phosphatidylcholine (PC) and phosphatidylethanolamine (PE) between membranes in vitro; changes in membrane composition of PC and PE occur before the morphological tumorigenic events. Interestingly, STARD10 has been described to be highly expressed in 35-40% of ERBB2-positive breast cancers. StarD10 was initially discovered based on its cross-reactivity with a phosphoserine-specific antibody in mammary tumors from Neu/ErbB2 transgenic mice and subsequently isolated from SKBR3 human breast carcinoma cells using a multistep biochemical purification strategy. StarD10 contains a steroidogenic acute regulatory protein (StAR/StarD1)-related lipid transfer (START) domain that is thought to mediate binding of lipids. STARD10 is highly expressed in the liver and has been shown to transfer phosphatidylcholine.
