Polyclonal Rabbit Affinity Purified B IH
STATs (signal transducers and activators of transcription) are a family of cytoplasmic latent transcription factors that are activated to regulate gene expression in response to a large number of extracellular signaling polypeptides including cytokines, interferons, and growth factors. STAT4 is activated when cells are treated with interleukin-12, a key cytokine regulator of cell-mediated immunity. Human STAT4 gene is mapped to chromosome 2q32.2-q32.3.
