Polyclonal Rabbit Affinity Purified E B IH
STATs were originally identified as DNA-binding proteins essential to interferon IFNa-and IFNg-regulated gene expression. Since then, several additional mammalian STATs, a Drosophila STAT (D-STAT or Marelle), and a STAT-like protein from Dictyostelium discoideum have been recognized. In unstimulated cells STAT proteins exist largely as latent cytoplasmic transcription factors. Treatment of cells with cytokines or certain growth factors results in the tyrosine phosphorylation (via Janus kinases for cytokines) of specific STATs causing them to form homodimers or heterodimers that enter the nucleus. In the nucleus, STAT dimers bind DNA and activate transcription of distinct target genes. Although several different STATs may be activated in response to a given ligand, there is often a striking specificity in the pattern of STAT activation. Mammalian STAT proteins share several conserved structural and functional domains as illustrated below.
