Abstract

Protein kinase C is a family of isozymes that are activated by hormone-stimulated phosphoinositide hydrolysis and participate in the signalling process by phosphorylating certain target proteins. In glomerular mesangial cells protein kinase C fulfills two major functions: it contributes to hormone-induced prostaglandin formation, and it acts as a negative feedback regulator of the inositol lipid signalling cascade. Furthermore, protein kinase C activates a phosphatidylcholine-degrading phospholipase D activity with as-yet-unknown cellular function.
