Serine/threonine-protein phosphatase 2B catalytic subunit beta isoform

Gene

PPP3CB

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Calcium-dependent, calmodulin-stimulated protein phosphatase which plays an essential role in the transduction of intracellular Ca2+-mediated signals (PubMed:19154138, PubMed:26794871). Dephosphorylates and activates transcription factor NFATC1 (PubMed:19154138). Dephosphorylates and inactivates transcription factor ELK1 (PubMed:19154138). Dephosphorylates DARPP32 (PubMed:19154138).2 Publications

Miscellaneous

Unlike for protein substrates, PPP3CB activity towards synthetic phosphatase substrate p-nitrophenyl phosphate (pNPP) is increased in presence of the immunosuppressant complex FKBP12-FK506.1 Publication

Catalytic activityi

[a protein]-serine/threonine phosphate + H2O = [a protein]-serine/threonine + phosphate.2 Publications

Cofactori

Protein has several cofactor binding sites:
  • Fe3+1 PublicationNote: Binds 1 Fe3+ ion per subunit.1 Publication
  • Zn2+1 PublicationNote: Binds 1 zinc ion per subunit.1 Publication

Activity regulationi

Activated by Ca2+-bound calmodulin following an increase in intracellular Ca2+. At low Ca2+ concentrations, the catalytic subunit (also known as calcineurin A) is inactive and is bound to the regulatory subunit (also known as calcineurin B) in which only two high-affinity binding sites are occupied by Ca2+. In response to elevated calcium levels, the occupancy of the low-affinity sites on calcineurin B by Ca2+ causes a conformational change of the C-terminal regulatory domain of calcineurin A, resulting in the exposure of the calmodulin-binding domain and in the partial activation of calcineurin A. The subsequent binding of Ca2+-bound calmodulin leads to the displacement of the autoinhibitory domain from the active site and possibly of the autoinhibitory segment from the substrate binding site which fully activates calcineurin A.2 Publications

    Subunit structurei

    Forms a complex composed of a calmodulin-dependent catalytic subunit (also known as calcineurin A) and a regulatory Ca2+-binding subunit (also known as calcineurin B). There are three catalytic subunits, each encoded by a separate gene (PPP3CA, PPP3CB, and PPP3CC) and two regulatory subunits which are also encoded by separate genes (PPP3R1 and PPP3R2). In response to an increase in Ca2+ intracellular levels, forms a complex composed of PPP3CB/calcineurin A, calcineurin B and calmodulin. Interacts (via calcineurin B binding domain) with regulatory subunit PPP3R1/calcineurin B. Interacts (via calmodulin-binding domain) with calmodulin; the interaction depends on calmodulin binding to Ca2+.1 Publication

    The poly-Pro domain may confer substrate specificity.1 Publication
    The autoinhibitory domain prevents access to the catalytic site.1 Publication
    The autoinhibitory segment prevents access to the substrate binding site.1 Publication
    Possible isomerization of Pro-318 within the SAPNY motif triggers a conformation switch which affects the organization and thus accessibility of the active site and the substrate binding region (PxIxIF motif). The trans- to cis-transition may favor calcineurin A activation and substrate binding. The reverse cis- to trans-transition may be enhanced by peptidyl-prolyl isomerases such as PPIA.By similarity
