defects including multipolar spindle formation, fragmentation of pericentriolar materials, and centrosome amplification were found. Cholesterol/oxysterol binding StarD1/D3 subfamily These proteins are primarily concerned with cholesterol transport StAR (STARD1) MLN64 (STARD3) StarD4 subfamily These proteins are involved in cholesterol and oxysterol transport STARD4 STARD5 STARD6 Phospholipid/sphingolipid binding StarD2 subfamily Phosphatidylcholine transfer protein (PCTP/STARD2) STARD7 STARD10 Collagen type IV alpha-3-binding protein (COL4A3BP/Ceramide transfer protein (CERT)/STARD11) SAM-RhoGAP-START subfamily These proteins contain both the START domain and Rho-GTPase signaling activity STARD8 (DLC-3) DLC1 (STARD12) STARD13 (DLC-2) Acyl-CoA thioesterase subfamily The members of this subfamily possess the START domain and thioesterase activity ACOT11 (STARD14) ACOT12 (STARD15) See also Sterol carrier protein References Peripheral membrane proteins Protein domains Water-soluble transporters
