Signal transducer and activator of transcription 2 is a protein that in humans is encoded by the STAT2 gene.[1][2]

The protein encoded by this gene 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. In response to interferon (IFN), this protein 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 this protein, which is thought to be involved in the process of blocking IFN-alpha response by adenovirus.[2]


STAT2 has been shown to interact with MED14,[3] CREB-binding protein,[4] SMARCA4,[5] STAT1,[6][7][8] IFNAR2,[9][10] IFNAR1[9][11][12] and ISGF3G.[13][14]
