specificity of phosphorylation of the retinoid-binding proteins was confirmed by polyacrylamide gel electrophoresis and subsequent autoradiography of the assay mixture as well as by a concentration-dependent , ca+2 , and phosphatidylserine sensitivity of the phosphorylation of both apo-crbp and apo-crabp .
