Protein attributes

Sequence length176 AA.
Sequence statusComplete.
Protein existenceEvidence at transcript level

General annotation (Comments)

Function

Regulatory subunit of calcineurin, a calcium-dependent, calmodulin stimulated protein phosphatase. Confers calcium sensitivity.

Subunit structure

Composed of a catalytic subunit (A) and a regulatory subunit (B).

Tissue specificity

Testis specific. Ref.1

Miscellaneous

This protein has four functional calcium-binding sites.

Sequence similarities

Belongs to the calcineurin regulatory subunit family.

Contains 4 EF-hand domains.

Sequence caution

The sequence AAB20281.1 differs from that shown. Reason: Erroneous initiation.
