Rabbit Anti-phospho-NFAT5 (Ser1197)/FITC Conjugated antibody
background:
Members of the NFAT (nuclear factor of activated T cells) family of transcription factors are related to NFkB/Rel proteins and form cooperative complexes with the AP-1 proteins, Fos and Jun, on DNA to regulate cytokine expression in T cells. NFAT proteins are widely expressed and alternatively modified to generate splice variants, and they are localized to both the cytosol (NFATc) and to the nucleus (NFATn). NFAT1, NFAT2, and NFAT4 are predominantly expressed in immune cells, and NFAT2 and NFAT3 are expressed at high levels in cardiac tissues. In addition to activating cytokine gene transcription, NFAT2 is also implicated in cardiac valve development, and NFAT3 is involved in cardiac hypertrophy. NFAT5 is detected in both immune and nonimmune cells and, like other NFAT proteins, contains a highly conserved Rel-like binding domain that mediates NFAT proteins associating with specific consensus sequences on DNA. NFAT proteins are activated by increases in intracellular calcium, which leads to the calmodulin-dependent phosphatase, calcineurin, dephosphorylating NFAT proteins. This activating event induces a conformational change in the protein structure that exposes the nuclear localization signal and facilitates the translocation of NFAT proteins from the cytosol into the nucleus.
Function:
Plays a role in the inducible expression of genes.Regulates hypertonicity-induced cellular accumulation of osmolytes.
Subunit:
Homodimer when bound to DNA, completely encircles its DNAtarget. Does not bind with Fos and Jun transcription factors.
Subcellular Location:
Nucleus.
Tissue Specificity:
Highest levels in skeletal muscle, brain, heart and peripheral blood leukocytes. Also expressed in placenta, lung, liver, kidney, pancreas, spleen, thymus, prostate, testis, ovary, small intestine and colon.
Post-translational modifications:
Phosphorylated at Thr-135 by CDK5 in response to osmoticstress; this phosphorylation mediates its rapid nuclearlocalization.
Similarity:
Contains 1 RHD (Rel-like) domain.
