a Ca(2 )/calmodulin-dependent protein kinase of the PHK family. Phosphorylase kinase is a polymer of 16 chains, four each of alpha, beta, gamma, and delta. Alpha and beta are regulatory chains, gamma is the catalytic chain, and delta is calmodulin. This isozyme may regulate glycogeneolysis in the testis.
