Definitions for "Protein kinase C"
Enzyme that phosphorylates certain intracellular proteins when activated by diacylglycerol.
Enzyme that catalyzes the transfer of high-energy phosphate group from ATP to an acceptor protein. This phosphorylation converts an inactive protein (enzyme) to the active form.
A family of a few different proteins that catalyze the phosphorylation of tyrosine residues in proteins, effectively activating some and inactivating others. In this paper, "an increase in PKC" specifically means an increase not just in PKCa, but also the PKC?, PKC? isoforms. All three PKCs require calcium for activation, and PKCa plays a role in controlling infection by intracellular parasites such as Legionella pneumophila.
