Phorbol 12-myristate 13-acetate is a potent tumor promoter and activates protein kinase C
in vivo and
in vitro. It is a phorbol ester that is associated with many cellular responses including gene transcription, cell division and differentiation, apoptosis and immune response. It is also involved in protein kinase C (PKC) mediated receptor desensitization.
[4] Phorbol 12-myristate 13-acetate induces PKC localization from the cytosol,
[5] enabling the enzyme association with the cell membrane.
