英文摘要
We performed genetic biochemical screenings with shiga toxin to look for new factors that affect glycosphingolipid (GSL) metabolism and its intracellular traffic. As a molecule to reduce Gb3, the shiga toxin receptor, we isolated the COOH-terminus region of GRINA, a member of TMBIM family, which was named GRINA-C. Overexpression of GRINA-C and FAIM2, another TMBIM family member, affected the amount of Gb3 synthase and its intracellular localization, suggesting a new type of regulation of glycosyltransferases in GSL metabolism.
