Expression of an active form of Ras , Ras(G12V) , suppressed the IL-2 -induced beta-casein and OSM gene expression , and the negative effect of Ras is mediated by the region between -105 and -193 in the beta-casein promoter .
 DNA: beta-casein promoter; protein: beta-casein; protein: beta-casein; protein: OSM; protein: Ras(G12V); DNA: -105 and -193; protein: Ras; protein: Ras; protein: IL-2
