| Description | STAT2 is a member of the STAT protein family. In response to interferon, STAT2 forms a complex with STAT1 and IFN regulatory factor family protein p48 (ISGF3G), in which this protein acts as a transactivator, but lacks the ability to bind DNA directly [ ]. Transcription adaptor P300/CBP (EP300/CREBBP) has been shown to interact specifically with STAT2, which is thought to be involved in the process of blocking IFN-alpha response by adenovirus [].STAT proteins have a dual function: signal transduction and activation of transcription. When cytokines are bound to cell surface receptors, the associated Janus kinases (JAKs) are activated, leading to tyrosine phosphorylation of the given STAT proteins []. Phosphorylated STATs form dimers, translocate to the nucleus, and bind specific response elements to activate transcription of target genes []. STAT proteins contain an N-terminal domain (NTD), a coiled-coil domain (CCD), a DNA-binding domain (DBD), an α-helical linker domain (LD), an SH2 domain, and a transactivation domain (TAD). The SH2 domain is necessary for receptor association and tyrosine phosphodimer formation. There are seven mammalian STAT family members which have been identified: STAT1, STAT2, STAT3, STAT4, STAT5 (STAT5A and STAT5B), and STAT6 []. | Name | STAT2, SH2 domain |
