Status
Functioni
Calcium-dependent, calmodulin-stimulated protein phosphatase which plays an essential role in the transduction of intracellular Ca2+-mediated signals (PubMed:15671020, PubMed:18838687, PubMed:19154138, PubMed:23468591). Many of the substrates contain a PxIxIT motif and/or a LxVP motif (PubMed:17498738, PubMed:17502104, PubMed:23468591, PubMed:27974827, PubMed:22343722). In response to increased Ca2+ levels, dephosphorylates and activates phosphatase SSH1 which results in cofilin dephosphorylation (PubMed:15671020). In response to increased Ca2+ levels following mitochondrial depolarization, dephosphorylates DNM1L inducing DNM1L translocation to the mitochondrion (PubMed:18838687). Dephosphorylates heat shock protein HSPB1 (By similarity). Dephosphorylates and activates transcription factor NFATC1 (PubMed:19154138). In response to increased Ca2+ levels, regulates NFAT-mediated transcription probably by dephosphorylating NFAT and promoting its nuclear translocation (PubMed:26248042). Dephosphorylates and inactivates transcription factor ELK1 (PubMed:19154138). Dephosphorylates DARPP32 (PubMed:19154138).By similarity9 Publications
Miscellaneous
Although African swine fever virus infects pigs and not humans, human PPP3CA has been used for the crystallization. PPP3CA interacts with African swine fever virus Mal-047/A238L (via PKIIIT and FLCVK motifs); the interaction does not block catalytic activity per se but inhibits PPP3CA function by blocking the access to the two substrate recognition sites.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. Inhibited by immunosuppressant drug FK506 (tacrolimus) in complex with FKBP12 and also by immunosuppressant drug cyclosporin A (CsA) in complex with PPIA/cyclophilin A; the inhibition is Ca2+-dependent (PubMed:26248042).By similarity1 Publication

The autoinhibitory domain prevents access to the catalytic site.By similarity
The autoinhibitory segment prevents access to the substrate binding site.By similarity
Possible isomerization of Pro-309 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.1 Publication
