Forms a complex composed of a calmodulin-dependent catalytic subunit (also known as calcineurin A) and a regulatory Ca(2+)-binding subunit (also known as calcineurin B) (PubMed:8524402, 12218175, 12357034, 17498738, 22343722, 23468591, 27974827). 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 Ca(2+) intracellular levels, forms a complex composed of PPP3CA/calcineurin A, calcineurin B and calmodulin (By similarity). Interacts (via calcineurin B binding domain) with regulatory subunit PPP3R1/calcineurin B (PubMed:8524402, 12218175, 12357034, 17498738, 22343722, 23468591, 27974827). Interacts (via calmodulin-binding domain) with CALM1/calmodulin; the interaction depends on calmodulin binding to Ca(2+) (PubMed:18384083, Ref. 33, PubMed:19404396, PubMed:25144868). Forms a complex composed of MYOZ2 and ACTN1 (By similarity). Within the complex interacts with MYOZ2 (PubMed:11114196). Interacts with MYOZ1 (PubMed:11114196). Interacts with MYOZ3 (PubMed:11842093). Interacts with CIB1; the interaction increases upon cardiomyocyte hypertrophy (By similarity). Interacts with CHP1 and CHP2 (By similarity). Interacts with CRTC1 (PubMed:30611118). Interacts with CRTC2 (PubMed:15454081, 30611118). Interacts with DNM1L; the interaction dephosphorylates DNM1L and promotes its translocation to mitochondria (PubMed:18838687). Interacts with CMYA5; this interaction represses calcineurin activity in muscle (By similarity). Interacts (constitutively active form) with SYNPO2 (PubMed:17923693). Interacts with scaffold protein AKAP5 (via IAIIIT motif); the interaction recruits PPP3CA to the plasma membrane following L-type Ca(2+)-channel activation (PubMed:22343722). Interacts with NFATC2 (PubMed:26248042). Interacts with RCAN3 (PubMed:26248042). Interacts with PPIA (PubMed:12218175, 12357034). Interacts with RCAN1 (PubMed:12809556). Interacts with UNC119 (By similarity). Interacts with C16orf74 (via PxIxIT motif, when phosphorylated on 'Thr-44') (PubMed:28881575). Interacts (via N-terminus) with MAP3K14/NIK (via C-terminus and kinase domain) (By similarity). Interacts with TRAF3 (By similarity). Interacts with SPATA33 (via PQIIIT motif) (PubMed:34446558).
