NCIt definition : A family of serine/threonine protein kinases that have a structurally conserved catalytic
subunit and a regulatory subunit that are connected by a hinge domain.;
Alternative definition : NCI-GLOSS: An enzyme found throughout the body's tissues and organs. Several forms
of PKC are involved in many cellular functions. PKC is being studied in the treatment
of cancer.;
NCIt note : There are 3 classes of protein kinase C isozymes based on the molecular requirement
for activation. Conventional isozymes need calcium ions, diacylglycerol and phospholipids
for activation. Novel isozymes require diacylglycerol and are not regulated by calcium
ions, while atypical isozymes require neither diacylglycerol nor calcium ions.;
