Peptide phosphorylation by purified wild-type and mutant cytoplasmic domains. The preautophosphorylated proteins (800 nM) were incubated with 1 mM peptide (KKEEEEYMMMMG) and 1 mM ATP, and activity was measured using the phosphocellulose paper binding assay. Reactions proceeded for 20 minutes at 30°C. Assays were conducted in triplicate, and the results are presented as mean ± standard deviation
