| Brg 1 , the ATP hydrolyzing component of the SWI / SNF complex , along with the BAF57 / p50 and Ini 1 subunits could be co immunoprecipitated from cells with ets 2 . ^^^ The pointed domain of ets 2 directly interacted in vitro with the C terminal region of Brg 1 in a phosphorylation dependent manner . ^^^ The combination of Brg 1 and ets 2 could repress the BRCA 1 promoter reporter in transfection assays . ^^^ |
