Abstract
We have purified a 38 kDa protein from bovine brain which is cross-reactive with an affinity purified antibody against the 35 kDa phosphatidylino-sitol transfer protein from the same source. Controlled trypsinization of the 38 kDa protein yielded an immunoreactive protein of 35 kDa which displayed a 6-fold increase in phosphatidylinositol transfer activity and a IO-fold higher affinity for this phospholipid. The possibility that the 38 kDa protein is a precursor of the phosphatidylinositol transfer protein is discussed.(C) 1990 Elsevier Science B.V. All rights reserved.
