CC   -!- FUNCTION: Calcium-dependent, calmodulin-stimulated protein phosphatase
CC       which plays an essential role in the transduction of intracellular
CC       Ca(2+)-mediated signals (PubMed:7791792, PubMed:26794871). Many of the
CC       substrates contain a PxIxIT motif and/or a LxVP motif (By similarity).
CC       In response to increased Ca(2+) levels, dephosphorylates and activates
CC       phosphatase SSH1 which results in cofilin dephosphorylation (By
CC       similarity). In response to increased Ca(2+) levels following
CC       mitochondrial depolarization, dephosphorylates DNM1L inducing DNM1L
CC       translocation to the mitochondrion (By similarity). Positively
CC       regulates the CACNA1B/CAV2.2-mediated Ca(2+) release probability at
CC       hippocampal neuronal soma and synaptic terminals (By similarity).
CC       Dephosphorylates heat shock protein HSPB1 (By similarity).
CC       Dephosphorylates and activates transcription factor NFATC1 (By
CC       similarity). Dephosphorylates and inactivates transcription factor ELK1
CC       (By similarity). Dephosphorylates DARPP32 (By similarity). May
CC       dephosphorylate CRTC2 at 'Ser-171' resulting in CRTC2 dissociation from
CC       14-3-3 proteins (By similarity). Required for postnatal development of
CC       the nephrogenic zone and superficial glomeruli in the kidneys, cell
CC       cycle homeostasis in the nephrogenic zone, and ultimately normal kidney
CC       function (PubMed:15509543). Plays a role in intracellular AQP2
CC       processing and localization to the apical membrane in the kidney, may
CC       thereby be required for efficient kidney filtration (PubMed:16735444).
CC       Required for secretion of salivary enzymes amylase, peroxidase,
CC       lysozyme and sialic acid via formation of secretory vesicles in the
CC       submandibular glands (PubMed:21435446). Required for calcineurin
CC       activity and homosynaptic depotentiation in the hippocampus
CC       (PubMed:10200317). Required for normal differentiation and survival of
CC       keratinocytes and therefore required for epidermis superstructure
CC       formation (PubMed:19626032). Positively regulates osteoblastic bone
CC       formation, via promotion of osteoblast differentiation
CC       (PubMed:16286645). Positively regulates osteoclast differentiation,
CC       potentially via NFATC1 signaling (PubMed:16968888). May play a role in
CC       skeletal muscle fiber type specification, potentially via NFATC1
CC       signaling (PubMed:12773574). Negatively regulates MAP3K14/NIK signaling
CC       via inhibition of nuclear translocation of the transcription factors
CC       RELA and RELB (PubMed:26029823). Required for antigen-specific T-cell
CC       proliferation response (PubMed:8627154). Dephosphorylates KLHL3,
CC       promoting the interaction between KLHL3 and WNK4 and subsequent
CC       degradation of WNK4 (By similarity). Negatively regulates SLC9A1
CC       activity (By similarity). {ECO:0000250|UniProtKB:P48452,

CC         Evidence={ECO:0000269|PubMed:26794871};
CC       Note=Binds 1 zinc ion per subunit. {ECO:0000269|PubMed:26794871};
CC   -!- ACTIVITY REGULATION: Activated by Ca(2+)-bound calmodulin following an
CC       increase in intracellular Ca(2+) (PubMed:26794871). At low Ca(2+)
CC       concentrations, the catalytic subunit (also known as calcineurin A) is
CC       inactive and is bound to the regulatory subunit (also known as
CC       calcineurin B) in which only two high-affinity binding sites are
CC       occupied by Ca(2+) (PubMed:26794871). In response to elevated calcium
CC       levels, the occupancy of the low-affinity sites on calcineurin B by
CC       Ca(2+) causes a conformational change of the C-terminal regulatory
CC       domain of calcineurin A, resulting in the exposure of the calmodulin-
CC       binding domain and in the partial activation of calcineurin A
CC       (PubMed:26794871). The subsequent binding of Ca(2+)-bound calmodulin
CC       leads to the displacement of the autoinhibitory domain from the active
CC       site and possibly of the autoinhibitory segment from the substrate
CC       binding site which fully activates calcineurin A (PubMed:26794871).
CC       Inhibited by immunosuppressant drug FK506 (tacrolimus) in complex with
CC       FKBP12 and also by immunosuppressant drug cyclosporin A (CsA) in
CC       complex with PPIA/cyclophilin A; the inhibition is Ca(2+)-dependent (By
CC       similarity). {ECO:0000250|UniProtKB:P48452,
CC       ECO:0000269|PubMed:26794871}.
CC   -!- SUBUNIT: Forms a complex composed of a calmodulin-dependent catalytic
CC       subunit (also known as calcineurin A) and a regulatory Ca(2+)-binding
CC       subunit (also known as calcineurin B) (PubMed:26794871). There are
CC       three catalytic subunits, each encoded by a separate gene (PPP3CA,
CC       PPP3CB, and PPP3CC) and two regulatory subunits which are also encoded
CC       by separate genes (PPP3R1 and PPP3R2). In response to an increase in
CC       Ca(2+) intracellular levels, forms a complex composed of
CC       PPP3CA/calcineurin A, calcineurin B and calmodulin (By similarity).
CC       Interacts (via calcineurin B binding domain) with regulatory subunit
CC       PPP3R1/calcineurin B (PubMed:26794871). Interacts (via calmodulin-
CC       binding domain) with calmodulin; the interaction depends on calmodulin
CC       binding to Ca(2+) (By similarity). Forms a complex composed of MYOZ2
CC       and ACTN1 (PubMed:11114196). Within the complex interacts with MYOZ2
CC       (PubMed:11114196). Interacts with MYOZ1 (PubMed:11114196). Interacts
CC       with MYOZ3 (By similarity). Interacts with CIB1; the interaction
CC       increases upon cardiomyocyte hypertrophy (PubMed:20639889). Interacts
CC       with CHP1 and CHP2 (By similarity). Interacts with CRTC1
CC       (PubMed:30611118). Interacts with CRTC2 (PubMed:30611118). Interacts
CC       with DNM1L; the interaction dephosphorylates DNM1L and promotes its
CC       translocation to mitochondria (By similarity). Interacts with CMYA5;
CC       this interaction represses calcineurin activity in muscle
CC       (PubMed:21427212). Interacts (constitutively active form) with SYNPO2
CC       (By similarity). Interacts with scaffold protein AKAP5 (via IAIIIT
CC       motif); the interaction recruits PPP3CA to the plasma membrane
CC       following L-type Ca(2+)-channel activation (By similarity). Interacts
CC       with NFATC2 (By similarity). Interacts with RCAN3 (By similarity).
CC       Interacts with PPIA (By similarity). Interacts with RCAN1

CC   -!- DISRUPTION PHENOTYPE: Knockout mice are significantly smaller at
CC       postnatal day 18 (P18), including significantly reduced weights of the
CC       liver and kidneys (PubMed:15509543, PubMed:16735444). Decreased blood
CC       glucose levels (PubMed:16735444). Decreased lumber spine, tibia, and
CC       total body bone mass density evident at 6 weeks of age, evidence of
CC       decreased density in the lumber spine as early as 3 weeks of age
CC       (PubMed:16286645). No change in overall muscle weight
CC       (PubMed:12773574). Decreased femur length, reduced cortical trabecular
CC       bone thickness (PubMed:16286645). Significantly reduced number of
CC       differentiated osteoclasts (PubMed:16968888). Reduced mitochondrial
CC       oxidative capacity in slow and intermediate muscle fiber types
CC       (PubMed:12773574). Reduced slow and intermediate program type muscle
CC       fibers in the biceps and triceps (PubMed:12773574). Decreased number of
CC       slow program type muscle fibers and NFAT activity in the soleus
CC       (PubMed:12773574). Kidney size and development is normal at P4, however
CC       by P18 kidneys show an obvious delay in maturation, displaying a
CC       decreased overall mass, poorly defined medullary rays and decreased

CC       the medulla and cortical regions of the kidneys are significantly
CC       decreased (PubMed:15509543). In the cortex there is a persistence of
CC       poorly developed surface glomeruli due to attenuation of mesangial
CC       cells numbers and a lack of maturation of tubules in the nephrogenic
CC       zone (PubMed:15509543). Reduced proliferation and increased apoptosis
CC       of cells within the nephrogenic zone at P18, potentially as a result of
CC       increased p27 expression (PubMed:15509543). Impaired kidney function
CC       evident by increased kidney collagen deposition, serum creatinine
CC       levels and decreased urine creatinine concentration from P4 onwards
CC       (PubMed:15509543, PubMed:16735444). Loss of AQP2 phosphorylation in
CC       response to vasopressin and decreased localization to the apical

CC       failure (PubMed:15509543). Increased salivary osmolality despite normal
CC       electrolyte composition and protein content (PubMed:21435446).
CC       Decreased activity of amylase, peroxidase, lysozyme and sialic acid in
CC       the saliva (PubMed:21435446). Decreased number of secretory vesicles,

CC       thickness of the epidermal stratum spinosum, a thickened corneum and
CC       increased sloughing-off of keratinocytes in newborn mice
CC       (PubMed:19626032). Decreased thickness of the stratum spinosum is still
CC       evident at 4 weeks of age along with decreased skin elasticity
CC       (PubMed:19626032). Increased apoptosis in the supra-basal layers and
CC       the stratum spinosum of the epidermis (PubMed:19626032). Decrease in
CC       NFATc activity in basal epidermal cells and impaired differentiation of
CC       epidermal keratinocytes as shown by aberrant expression of the
CC       differentiation markers KRT14, KRT10 and IVL (PubMed:19626032).
CC       Decreased calcineurin activity in the brain and significant reduction
CC       in homosynaptic depotentiation (PubMed:10200317). Decreased calcineurin
