cAMP-dependent phosphorylation of bovine lens alpha-crystallin.


This communication reports that the A1 and B1 chains of bovine lens alpha-crystallin are phosphorylated. The conclusion is based on the following evidence: (i) When soluble preparations from lens cortex are incubated with [gamma-32P]ATP, a cAMP-dependent labeling of a high molecular weight protein is obtained. (ii) After NaDodSO4/PAGE, the label is found in… (More)
