General description
A macrocyclic lactone that exhibits anti-tumor properties. Potently activates protein kinase C and exhibits high binding affinity (Ki = 1.35 nM). Effectively translocates protein kinase C (PKC) isozymes α, β, and ε and induces a biphasic, concentration-dependent, down-regulation of PKC δ. Reported to compete with phorbol esters in binding to PKC. Stimulates protein kinase D (PKD) activity in a biphasic, PKC-dependent manner in intact cells. Also activates Ras in Jurkat T cells and in rat2 cells.
