STAT5A Protein, Human, Recombinant (His)

Signal transducer and activator of transcription 5A is a protein that in humans is encoded by the STAT5A gene. Many studies have indicated a key role of STAT5a in leukemia, breast, colon, head and neck, and prostate cancer. Until recently, the unique characteristics and function of STAT5a in these cancers have not been delineated from STAT5b, and more research into their differential behavior is warranted. Because of its integral role in immune cell development, STAT5a may contribute to tumor development by compromising immune surveillance.
