In response to cytokines and growth factors, STAT family members are Background Information phosphorylated by the receptor associated kinases, and then form homo- or heterodimers that translocate to the cell nucleus where they act as transcription activators. STAT5A is activated by, and mediates the responses of many cell ligands, such as IL2, IL3, IL7 GM-CSF, erythropoietin, thrombopoietin, and different GHs. Activation of STAT5A in myeloma and lymphoma associated with a TEL/JAK2 gene fusion is independent of cell stimulus and has been shown to be essential for the tumorigenesis. The mouse counterpart of human STAT5A is found to induce the expression of BCL2L1/BCL-X(L), which suggests the antiapoptotic function of STAT5A in cells. Storage: Storage Store at -20ºC.

Recently, the involvement of STAT5 signalling in the pathology of cancer has been shown to be of increasing importance. STAT5 plays a crucial role in the development of the mammary gland and the homeostasis of the immune system. However, in various cancers, aberrant STAT5 signalling promotes the expression of target genes, such as cyclin D, Bcl-2 and MMP-2, that result in increased cell proliferation, survival and metastasis. To target constitutive STAT5 signalling in cancers, there are several STAT5 inhibitors that can prevent STAT5 phosphorylation, dimerisation, or its transcriptional activity. Tyrosine kinase inhibitors (TKIs) that target molecules upstream of STAT5 could also be utilised. Consequently, since STAT5 contributes to tumour aggressiveness and cancer progression, inhibiting STAT5 constitutive activation in cancers that rely on its signalling makes for a promising targeted treatment option.

Activation Domain of Stat5 Trans
The IL-2 Receptor Promotes Lymphocyte Proliferation and Induction of the c-myc, bcl-2, and bcl-x Genes Through the trans-Activation Domain of Stat51 James D. Lord,*†‡ Bryan C. McIntosh,* Philip D. Greenberg,†‡§ and Brad H. Nelson2*‡ Studies assessing the role of Stat5 in the IL-2 proliferative signal have produced contradictory, and thus inconclusive, results. One factor confounding many of these studies is the ability of IL-2R to deliver redundant mitogenic signals from different cytoplasmic tyrosines on the IL-2R ␤-chain (IL-2R␤). Therefore, to assess the role of Stat5 in mitogenic signaling independent of any redun- dant signals, all cytoplasmic tyrosines were deleted from IL-2R␤ except for Tyr510, the most potent Stat5-activating site. This deletion mutant retained the ability to induce Stat5 activation and proliferation in the T cell line CTLL-2 and the pro-B cell line BA/F3. A set of point mutations at or near Tyr510 that variably compromised Stat5 activation also compromised the proliferative signal and revealed a quantitative correlation between the magnitude of Stat5 activation and proliferation. Proliferative signaling by a receptor mutant with a weak Stat5 activating site could be rescued by overexpression of wt Stat5a or b. Additionally, the ability of this receptor mutant to induce c-myc, bcl-x, and bcl-2 was enhanced by overexpression of wt Stat5. By contrast, overexpression of a version of Stat5a lacking the C-terminal trans-activation domain inhibited the induction of these genes and cell proliferation. Thus, Stat5 is a critical component of the proliferative signal from Tyr510 of the IL-2R and regulates expression of both mitogenic and survival genes through its trans-activation domain.
