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: -Experimental evidence at protein leveli

Functioni

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

Miscellaneous

Present with 7110 molecules/cell in log phase SD medium.1 Publication

Caution

Was originally thought to originate from a rabbit cDNA library and was known as protein phosphatase 2Bw (PP2Bw).1 Publication

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 Fe3+ ion per subunit.By similarity
  • Zn2+By similarityNote: Binds 1 zinc ion per subunit.By similarity
