Calcium-dependent, calmodulin-stimulated protein phosphatase which plays an essential role in the transduction of intracellular Ca2+-mediated signals (PubMed:1322410, PubMed:24018048).

Many of the substrates contain a PxIxIT motif and/or a LxVP motif (By similarity).

In response to increased Ca2+ levels, dephosphorylates and activates phosphatase SSH1 which results in cofilin dephosphorylation (By similarity).

In response to increased Ca2+ levels following mitochondrial depolarization, dephosphorylates DNM1L inducing DNM1L translocation to the mitochondrion (By similarity).

Dephosphorylates heat shock protein HSPB1 (By similarity).

Dephosphorylates and activates transcription factor NFATC1 (By similarity).

Dephosphorylates and inactivates transcription factor ELK1 (By similarity).

Dephosphorylates DARPP32 (By similarity).

May dephosphorylate CRTC2 at 'Ser-171' resulting in CRTC2 dissociation from 14-3-3 proteins (By similarity).

<p>This subsection of the <a href="http://www.uniprot.org/help/function%5Fsection">Function</a> section describes the catalytic activity of an enzyme, i.e. a chemical reaction that the enzyme catalyzes.<p><a href='/help/catalytic_activity' target='_top'>More...</a></p>Catalytic activityi

<p>This subsection of the 'Function' section provides information relevant to cofactors. A cofactor is any non-protein substance required for a protein to be catalytically active. Some cofactors are inorganic, such as the metal atoms zinc, iron, and copper in various oxidation states. Others, such as most vitamins, are organic.<p><a href='/help/cofactor' target='_top'>More...</a></p>Cofactori

Protein has several cofactor binding sites:

<p>This subsection of the <a href="http://www.uniprot.org/help/function%5Fsection">Function</a> section describes regulatory mechanisms for enzymes, transporters or microbial transcription factors, and reports the components which regulate (by activation or inhibition) the reaction.<p><a href='/help/activity_regulation' target='_top'>More...</a></p>Activity regulationi

Activated by Ca2+-bound calmodulin following an increase in intracellular Ca2+ (PubMed:1322410, PubMed:24018048). 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+ (PubMed:1322410, PubMed:24018048). 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 (PubMed:1322410, PubMed:24018048). 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 (PubMed:1322410, PubMed:24018048). 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 (By similarity).By similarity2 Publications

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).
