Protein
Signal transducer and activator of transcription 5A
Gene
STAT5A, MGF, STAT5
Organism
Ovis aries (Sheep)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

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.

Post-translational modificationi

Tyrosine phosphorylated in response to IL2, IL3, IL7, IL15, KITLG/SCF, CSF2/GMCSF, GH1, PRL, EPO and THPO. Tyrosine phosphorylated in response to constitutively activated FGFR1, FGFR2, FGFR3 and FGFR4. Tyrosine phosphorylated in response to signaling via activated FLT3 and KIT, resulting in translocation to the nucleus. 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. Dephosphorylation on tyrosine residues by PTPN2 negatively regulates prolactin signaling pathway By similarity.
ISGylated By similarity.
