Anti-NFATC4 antibodies are used in the immunodetection of the protein nuclear factor of activated T cells 4. In humans, the canonical protein has a reported length of 902 amino acid residues and a mass of 95.4 kDa. Its subcellular localization is in the nucleus and cytoplasm. Alternative splicing is reported to yield 24 different isoforms for this protein. It is found to be widely expressed, with high levels in placenta, lung, kidney, testis and ovary. Among its functions, NFATC4 is involved with cardiac tissue development and inflammatory response pathways. Post-translational modifications have been described, including ubiquitination and phosphorylation. Synonyms for this target antigen include NFAT3, nuclear factor of activated T-cells, cytoplasmic 4, T-cell transcription factor NFAT3, nuclear factor of activated T-cells, cytoplasmic, calcineurin-dependent 4, and NF-AT3.
