Signal transducer and activator of transcription 2, 113kDa

STAT2
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. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2010] (from NCBI)

Reyes-Leyva et al., Metepec, Mexico. In Viral Immunol, 28 Jan 2016
Complete loss of phosphorylated-signal transducer and activator of transcription (p-STAT)2 and reduced nuclear importation of p-STAT1 were observed in DENV-infected cells compared to IFN-α treatment that induced p-STAT1 and p-STAT2.
The immune evasion function of J and Beilong virus V proteins is distinct from that of other paramyxoviruses, consistent with a separate "Jeilongvirus" genus.

However, in contrast to most other paramyxoviruses, the JPV and BeiPV V proteins did not interact with nor inhibit signalling by STAT1 or STAT2, suggesting that JPV/BeiPV use an atypical V protein-independent strategy to target STATs, consistent with their inclusion in a separate genus.

Immune evasion by the lethal henipaviruses, Hendra (HeV) and Nipah virus, is mediated by its interferon (IFN) antagonist P gene products, phosphoprotein (P), and the related V and W proteins, which can target the signal transducer and activator of transcription 1 (STAT1) and STAT2 proteins to inhibit IFN/STAT signaling.
