An in vitro reconstitution/splicing complementation system has been developed which has allowed the investigation of the role of mammalian U2 and U5 snRNP components in splicing. U2 or U5 snRNP cores are first reconstituted from purified native snRNP core proteins and snRNA in the absence of cellular extract and are subsequently added to splicing extracts depleted of either U2 or U5 snRNP. When snRNPs reconstituted with HeLa U2 or U5 snRNA were added to U2- or U5-depleted nuclear extract… CONTINUE READING
