Stat 5a (STAT5A) Antibody – Rabbit Polyclonal

STAT5A: transcription factor of the STAT family. Phosphorylated and activated by receptor-associated kinases downstream of many cytokines and growth-factor receptors. Activation of this protein in myeloma and lymphoma associated with a TEL/JAK2 fusion protein is essential for the tumorigenesis. Induces the expression of BCL2L1/BCL-X(L) in the mouse, suggesting an antiapoptotic function of this protein. Forms homo- or heterodimers that translocate into the nucleus where they regulate transcription. Two alternatively spliced isoforms have been described.
