Anti-nuclear factor of activated T-cells 1 antibodies are protein reagents that detect specific antigens. The nuclear factor of activated T-cells 1 antigen is another term for the human protein nuclear factor of activated T cells 1, encoded by the NFATC1 gene. The protein is reported to play a role in the inducible expression of cytokine genes in T-cells, especially in the induction of the IL-2 or IL-4 gene transcription. Canonically, it has an amino acid length of 943 residues and a mass of 101.2 kilodaltons. Its subcellular localization is in the nucleus and cytoplasm and it is reported to be expressed in thymus, peripheral leukocytes as T-cells and spleen.
