PKCs
Definition: PKCs are members of the protein kinase C (PKC) family, a superfamily of serine/threonine kinases. They function in many extracellular receptor-mediated signal transduction pathways.
Protein kinase C (PKC) comprises a family of serine/threonine kinases that are involved in the transduction of signals for cell proliferation, differentiation, apoptosis and angiogenesis.
Disruption of PKC regulation is implicated in tumorigenesis and drug resistance.
PKC function is complex in this context owing to the differing roles of individual isozymes within the cell and across tumour types. PKC isozymes, effectors of diacylglycerol (DAG) and the main targets of phorbol-ester tumour promoters, have important roles in cell-cycle regulation, cellular survival, malignant transformation and apoptosis.
