摘要：Protein kinase C (PKC) isoforms, , {beta}I, and {gamma} of cPKC subgroup, {delta} and {varepsilon} of nPKC subgroup, and {zeta} of aPKC subgroup, were tyrosine phosphorylated in COS-7 cells in response to H2O2. These isoforms isolated from the H2O2-treated cells showed enhanced enzyme activity to various extents. The enzymes, PKC and {delta
