Protein kinase C epsilon type is an enzyme that in humans is encoded by the PRKCE gene.[1][2]


Protein kinase C (PKC) is a family of serine- and threonine-specific protein kinases that can be activated by calcium and the second messenger diacylglycerol. PKC family members phosphorylate a wide variety of protein targets and are known to be involved in diverse cellular signaling pathways. PKC family members also serve as major receptors for phorbol esters, a class of tumor promoters. Each member of the PKC family has a specific expression profile and is believed to play a distinct role in cells. The protein encoded by this gene is one of the PKC family members. This kinase has been shown to be involved in many different cellular functions, such as apoptosis, cardioprotection from ischemia, heat shock response, as well as insulin exocytosis.

Clinical significance

Knockout and molecular studies in mice suggest that this kinase is important for regulating behavioural response to morphine[3] and alcohol.[4][5] It also plays a role lipopolysaccharide (LPS)-mediated signaling in activated macrophages and in controlling anxiety-like behavior.[6]

Substrates and interactions

PKC-epsilon has a wide variety of substrates, including ion channels, other signalling molecules and cytoskeletal proteins.[7]

PKC-epsilon has been shown to interact with:
