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 the 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. [provided by RefSeq, Jul 2008]

靶标
基因名
STAT5A
蛋白名
Signal transducer and activator of transcription 5A
亚基
Forms a homodimer or a heterodimer with a related family member. Binds NR3C1. Interacts with NCOA1 and SOCS7. Interacts with ERBB4.
亚细胞定位
Cytoplasm. Nucleus. Note=Mostly cytoplasmic during pregnancy, whereas it becomes predominantly nuclear during early lactation. It is translocated into the nucleus in response to phosphorylation.
组织特异性
Expressed in heart, lung, and weakly in muscle.
翻译后修饰
Tyrosine phosphorylated in response to IL2, IL3, IL7, IL15, KITLG/SCF, CSF2/GMCSF, GH1, PRL, EPO and THPO. Tyrosine phosphorylated in response to signaling via activated FLT3 and KIT, resulting in translocation to the nucleus. Tyrosine phosphorylated in response to constitutively activated FGFR1, FGFR2, FGFR3 and FGFR4. Alternatively, can be phosphorylated by JAK2 at Tyr-694. Tyrosine phosphorylation is required for DNA-binding activity and dimerization. Serine phosphorylation is also required for maximal transcriptional activity (By similarity).
相似性
Belongs to the transcription factor STAT family. Contains 1 SH2 domain.
功能
Carries out a dual function: signal transduction and activation of transcription. Mediates cellular responses to the cytokine KITLG/SCF and other growth factors. 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.
