Engelsk definition
A monomeric calcium-calmodulin-dependent protein kinase subtype that specifically phosphorylates PEPTIDE ELONGATION FACTOR 2. The enzyme lacks a phosphorylatable activation domain that can respond to CALCIUM-CALMODULIN-DEPENDENT PROTEIN KINASE KINASE, however it is regulated by phosphorylation by PROTEIN KINASE A and through intramolecular autophosphorylation.
