STAT3

signal transducer and activator of transcription 3 (acute-phase response factor)

STAT3 is a member of the STAT protein family. 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 through phosphorylation in response to various cytokines and growth factors including IFNs, EGF, IL5, IL6, HGF, LIF and BMP2. This protein mediates the expression of a variety of genes in response to cell stimuli, and thus plays a key role in many cellular processes such as cell growth and apoptosis. The small GTPase Rac1 has been shown to bind and regulate the activity of this protein. PIAS3 protein is a specific inhibitor of this protein. Three alternatively spliced transcript variants encoding distinct isoforms have been described.

Gene Name: signal transducer and activator of transcription 3 (acute-phase response factor)
Synonyms: STAT3, Acute-phase response factor, APRF, DNA-binding protein APRF, HIES
Target Sequences: NM_003150 NP_003141.2 P40763
