Serine/threonine-protein phosphatase 2B catalytic subunit beta isoform (PP2BB) is an enzyme that in humans is encoded by the PPP3CB gene.

Function and Location

Enables different functions, including calmodulin dependent protein phosphatase: calmodulin binding; and binding protein phosphatase 2B.

Calcinuerin-NFAT signaling; lysosome organization; protein regulation to nucleaus.

Location

Found in the cytoplasm, and is a part of the calcinuerin complex.

Can be related with biomarkers of focal segments of schizophrenia.
