| Type: | Family | Name: | Nuclear factor of activated T-cells 1 |
| Description: | The protein is a member of the nuclear factors of activated T (NFAT) cells family of transcription factors. Proteins belonging to this group of transcription factors play a central role in inducible gene transcription during the immune response. The product of this gene is a pre-existing cytosolic component. It is present in the cytosolic fraction of un-stimulated T cells. After T-cell activation it is found in the nucleus as a part of the DNA-binding transcription complex. Two transcript variants encoding distinct isoforms have been identified for this gene, [] Mus musculus(Mouse) and Homo sapiens(Human).NFAT proteins appear to be regulated primarily at the level of their subcellular localisation []. They are found exclusively in the cytoplasm of resting T cells, and consist of 2 components: a pre-existing cytoplasmic component that translocates into the nucleus on calcium mobilisation, and an inducible nuclear component comprising members of the activating protein-1 (AP-1) family of transcription factors. In response to antigen receptor signalling, the calcium-regulated phosphatase calcineurin acts directly to dephosphorylate NFAT proteins, causing their rapid translocation from the cytoplasm to the nucleus, where they cooperatively bind their target.Synonym(s): NFATp,NFATC2 | Short Name: | NFAT1 |
