Taxonomic lineageEukaryotaFungiDikaryaBasidiomycotaAgaricomycotinaTremellomycetesTremellalesTremellaceaeFilobasidiellaFilobasidiella/Cryptococcus neoformans species complex

Protein attributes

Sequence length639 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 By similarity.

Catalytic activity

[a protein]-serine/threonine phosphate + H2O = [a protein]-serine/threonine + 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.

Sequence similarities

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