Differential effects of CaMKII inhibitors on PKCα and PKCγ. AKAP79(31–52) was incubated with PKCα and KN-93 (n = 3–4), KN-92 (n = 3–4), or CaMKIINtide (n = 8) as indicated (A) or PKCγ and KN-93 (n = 4–5; 100 nm, p < 0.01), KN-92 (n = 3; 1 μm, p < 0.05), or CaMKIINtide (n = 3–4; 100 nm, p < 0.05) (B). Left panels, representative blots for each condition. Right panels, summary data normalized to respective controls. All graphs depict mean ± S.E.
