title: A rapid purification method for neurogranin, a brain specific calmodulin-binding protein kinase C substrate.
abstract: A rapid purification method is reported for bovine brain neurogranin, a calmodulin-binding protein kinase C (PKC) substrate. This method takes advantage of the fact that the protein remains soluble in 2.5% perchloric acid (PCA) and that it binds to a calmodulin-Sepharose column in the absence of calcium: Other PKC substrate proteins that remain to be identified were also found to share these two properties, suggesting that a class of calmodulin-binding PKC substrates may exist in the brain.
