Organism
Xenopus laevis (African clawed frog)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at protein leveli

Functioni

Calmodulin mediates the control of a large number of enzymes, ion channels and other proteins by Ca2+. Among the enzymes to be stimulated by the calmodulin-Ca2+ complex are a number of protein kinases and phosphatases.
