As inferred from mouse (Okamura et al. 2000), calcineurin dephosphorylates NFATC2 at 13 serine residues (Batiuk et al. 1997, Kim et al. 2000). B lymphocytes also contain NFATC2 and NFATC3 which are inferred to undergo dephosphorylation at homologous serines. Dephosphorylation of NFATs exposes a nuclear localization signal which cause NFATs to be imported into the nucleus (Kim et al. 2000). In mouse, Calcineurin is observed to also transit into the nucleus in a complex with NFATs and may remain associated (Shibasaki et al. 1996).
