Clone Host Grade Applications
Polyclonal Rabbit Affinity Purified E B
A variety of cytokines and growth factors act through an induction of gene expression mediated by a family of latent transcription factors called STAT (Signal Transducers and Activators of Transcription) proteins. Cytokines, hormones and growth factors proceed through a sequence of steps that includes binding to receptors in the cytokine receptor superfamily followed by the activation of the JAK family of tyrosine kinases, which results in the activation of STAT proteins. STAT3, a 86kD protein, serves as a signaling molecule for many cytokines, such as IL-6, and growth-factor receptors, such as EGF. Necessary for murine fetal development, STAT3 is also expressed in a number of human tumors. STAT3 is activated by JAK1 via phosphorylation at its Tyr705, which induces dimerization, nuclear translocation and DNA binding. Transcriptional activation of STAT3 is regulated by the MAPK or mTOR pathway via phosphorylation at its Ser727.
