Target Information
STAT5 alpha is a member of the STAT family of transcription factors. In response to cytokines and growth factors, STAT family members are phosphorylated by receptor-associated kinases, forming homo- or heterodimers that translocate to the nucleus and act as transcription activators. STAT5 alpha mediates responses to ligands such as IL2, IL3, IL7, GM-CSF, erythropoietin, thrombopoietin, and growth hormones. Activation of STAT5 alpha in myeloma and lymphoma associated with TEL/JAK2 gene fusion is independent of cell stimulus and essential for tumorigenesis.
In mice, STAT5 alpha induces expression of BCL2L1/BCL-X(L), suggesting an antiapoptotic role. STAT5 alpha and STAT5 beta share 96% sequence similarity and are co-expressed in most tissues, with differential mRNA accumulation in muscle and mammary tissue. STAT5 alpha is critically involved in reproduction, lactation, immune function, and somatic growth.
