Protein attributes

Sequence length534 AA.
Sequence statusComplete.
Protein existenceInferred from homology

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 + H2O = a protein + phosphate.

Cofactor

Binds 1 Fe3+ 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 By similarity.

Sequence similarities

Belongs to the PPP phosphatase family. PP-2B subfamily.

Sequence caution

The sequence EAL91665.1 differs from that shown. Reason: Erroneous initiation.
