RC TISSUE=Brain; RX PubMed=7654206; DOI=10.1042/bj3100643; RA de Vries K.J., Heinrichs A.A., Cunningham E., Brunink F., Westerman J., RA Somerharju P.J., Cockcroft S., Wirtz K.W., Snoek G.T.; RT "An isoform of the phosphatidylinositol-transfer protein transfers RT sphingomyelin and is associated with the Golgi system."; RL Biochem. J. 310:643-649(1995). CC -!- FUNCTION: Catalyzes the transfer of phosphatidylinositol (PI) and CC phosphatidylcholine (PC) between membranes (PubMed:7654206). Shows a CC preference for PI and PC containing shorter saturated or monosaturated CC acyl chains at the sn-1 and sn-2 positions (By similarity). Preference CC order for PC is C16:1 > C16:0 > C18:1 > C18:0 > C20:4 and for PI is CC C16:1 > C16:0 > C18:1 > C18:0 > C20:4 > C20:3 (By similarity). CC {ECO:0000250|UniProtKB:Q00169, ECO:0000269|PubMed:7654206}.
