|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.|
|Precautions||Stat-5 alpha Antibody (C-term) is for research use only and not for use in diagnostic or therapeutic procedures.|
|Function||Carries out a dual function: signal transduction and activation of transcription. Mediates cellular responses to the cytokine KITLG/SCF and other growth factors. Mediates cellular responses to ERBB4. May mediate cellular responses to activated FGFR1, FGFR2, FGFR3 and FGFR4. Binds to the GAS element and activates PRL-induced transcription. Regulates the expression of milk proteins during lactation.|

Signal transducer and activator of transcription 5 (Stat5) functions both in signal transduction and activation of transcription. It has been found that cytoplasmic Stat5 is translocated to the nucleus in response to phosphorylation. Stat5 is tyrosine phosphorylated in response to IL-2, IL-3, IL-7, IL-15, GM-CSF, growth hormone, prolactin, erythropoietin and thrombopoietin (1,2). Tyrosine phosphorylation is required for DNA-binding activity and dimerization. Serine phosphorylation is also required for maximal transcriptional activity. NCoA-1/SRC-1 acts as a coactivator for both the a- and b-isoforms of Stat5 (3).
