Protein

Serine/threonine-protein phosphatase 2B catalytic subunit A2

Gene

CMP2

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Calcium-dependent, calmodulin-stimulated protein phosphatase. This subunit may have a role in the calmodulin activation of calcineurin.

Catalytic activityi

[a protein]-serine/threonine phosphate + H2O = [a protein]-serine/threonine + phosphate.

Cofactori

Protein has several cofactor binding sites:
  • Fe3+By similarityNote: Binds 1 Fe(3+) ion per subunit.By similarity
  • Zn2+By similarityNote: Binds 1 zinc ion per subunit.By similarity
