OverviewNCBI Gene
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 neuron channel activation, apoptosis, cardioprotection from ischemia, heat shock response, as well as insulin exocytosis. Knockout studies in mice suggest that this kinase is important for lipopolysaccharide (LPS)-mediated signaling in activated macrophages and may also play a role in controlling anxiety-like behavior.

Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads PRKCE as an antibody target. Whether an autoantibody or antibody against PRKCE could matter depends on whether native PRKCE is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
PRKCE is annotated at the cell surface, where native PRKCE is exposed to circulating antibodies and is a prime autoantibody target that could block, deplete, or overstimulate it.
Annotation status
The present source text does not explicitly label PRKCE as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
