The protein encoded by this gene is a member of the STAT family of transcription factors. In response to cytokines and growth factors, STAT family members are phosphorylated by the receptor associated kinases, and then form homo- or heterodimers that translocate to the cell nucleus where they act as transcription activators. This protein is activated by, and mediates the responses of many cell ligands, such as IL2, IL3, IL7 GM-CSF, erythropoietin, thrombopoietin, and different growth hormones. Activation of this protein in myeloma and lymphoma associated with a TEL/JAK2 gene fusion is independent of cell stimulus and has been shown to be essential for tumorigenesis. The mouse counterpart of this gene is found to induce the expression of BCL2L1/BCL-X(L), which suggests the antiapoptotic function of this gene in cells. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Dec 2013]
GeneCards Summary for STAT5A Gene
STAT5A (Signal Transducer And Activator Of Transcription 5A) is a Protein Coding gene. Diseases associated with STAT5A include aggressive systemic mastocytosis and human t-cell leukemia virus type 2. Among its related pathways are PI-3K cascade and PI-3K cascade. GO annotations related to this gene include sequence-specific DNA binding transcription factor activity and signal transducer activity. An important paralog of this gene is STAT1.
UniProtKB/Swiss-Prot for STAT5A Gene
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.
