Enables DNA binding activity. Acts upstream of or within positive regulation of gene expression; positive regulation of transcription by RNA polymerase II; and regulation of calcineurin-NFAT signaling cascade. Located in cytoplasm and nucleus. Is expressed in several structures, including alimentary system; cardiovascular system; endocrine gland; genitourinary system; and midbrain roof plate. Orthologous to human NFAT5 (nuclear factor of activated T cells 5). [provided by Alliance of Genome Resources, Apr 2022]
