01

Overview

Protein kinase C epsilon (PKCε) is a member of the protein kinase C (PKC) family, which are serine/threonine kinases involved in a wide range of cellular signaling pathways. PKCε is classified as a "novel" PKC isoform due to its calcium-independent but diacylglycerol/phorbol ester-dependent activation. It plays a key role in cardiac function, immune responses, neuronal signaling, and metabolism. Dysregulation of PKCε is implicated in various diseases, including cancer, diabetes, and cardiovascular disorders.
