Calmodulin was isolated as an electrophoretically homogeneous protein from bovine posterior pituitary glands. The yield indicated that this gland is a particularly rich source. Purified bovine posterior pituitary calmodulin and bovine brain calmodulin had identical electrophoretic mobilities on 10% and 12% polyacrylamide gels. The protein was further identified by molecular weight determination and by amino acid analysis which showed that it contained trimethyllysine, one residue per molecule. Bovine posterior pituitary calmodulin was found to activate a preparation of calmodulin-deficient phosphodiesterase from bovine heart. In addition, pituitary calmodulin stimulated Ca+ + Mg2+-ATPase activity associated with a purified nerve ending plasma membrane fraction. This dependence could only be demonstrated after successive washing of the membranes with EGTA buffers, a procedure designed to remove endogenous calmodulin.
