Protein

Serine/threonine-protein phosphatase 2B catalytic subunit

Gene

cnaA

Organism
Emericella nidulans (strain FGSC A4 / ATCC 38163 / CBS 112.46 / NRRL 194 / M139) (Aspergillus nidulans)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Protein inferred from homologyi

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