Protein attributes

Sequence length	502 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at transcript level.

General annotation (Comments)

Function	Calcium-dependent, calmodulin-stimulated protein phosphatase. This subunit may have a role in the calmodulin activation of calcineurin.
Catalytic activity	A phosphoprotein + H(2)O = a protein + phosphate.
Cofactor	Binds 1 Fe(3+) ion per subunit By similarity. Binds 1 zinc ion per subunit By similarity.
Subunit structure	Composed of two components (A and B), the A component is the catalytic subunit and the B component confers calcium sensitivity.
Tissue specificity	Testis.
Sequence similarities	Belongs to the PPP phosphatase family. PP-2B subfamily.
