Conversion of an apparent 100 kDa folate binding protein from human milk, choroid plexus and semen to a 25 kDa molecular species by phosphatidylinositol-specific phospholipase C
Abstract : Gel filtration studies in the presence of Triton X-100 showed that treatment with phosphatidylinositol-specific phospholipase C reduced the apparent molecular size of the 100 kDa folate binding protein from human milk, choroid plexus and semen to 25 kDa. Cleavage of a hydrophobic glycosly phosphatidylinositol domain (a membrane anchor) inserting the protein into Triton X-100 micelles could account for this phenomenon.
