Detection of Human NFATC3 by Western Blot. Western blot shows lysates of 293T human embryonic kidney cell line, HeLa human cervical epithelial carcinoma cell line, and Jurkat human acute T cell leukemia cell line. PVDF Membrane was probed with 1 µg/mL of Human NFATC3 Monoclonal Antibody (Catalog # MAB5834) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for NFATC3 at approximately 140 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

NFATC3 (Nuclear factor of activated T cells C3; also NFAT4 and NFATx) is a 145-150 kDa member of the NFAT family of transcription factors. NFATC3 is widely expressed being found in DP thymocytes, CD4+ T cells, smooth muscle cells, Schwann cells and mast cells. NFATC3 regulates gene transcription as part of a NFATC transcription complex. It is normally cytoplasmic and phosphorylated. Upon a rise in intracellular Ca+2, dephosphorylation occurs via calcineurin, and NFATC3 enters the nucleus. Human NFATC3 is 1075 amino acids (aa) in length. It contains a calcineurin binding site (aa 109-114), two NLSs (aa 273-275 and 686‑688), one NES (aa 1032-1041) and an RHD that binds DNA (aa 433-592). There are multiple isoforms. Thirty amino acid, 33 aa and 10 aa substitutions for aa 1036‑1075 are known that may be accompanied by an alternate start site at Met480. Over aa 900-1035, human NFATC3 shares 93% aa identity with mouse NFATC3.
