| Endogenous DRIP 150 and STAT 2 were able to interact in solution , and DNA affinity chromatography and chromatin immunoprecipitation assays demonstrated that DRIP 150 binds to the mature , activated ISGF 3 DNA complex and is recruited to target gene promoters in an IFN dependent fashion . 1.2314702^^^ The site of STAT 2 interaction was mapped to DRIP 150 residues 188 to 566 , which are necessary and sufficient for interaction with STAT 2 . 0.66423787^^^ |
