Highlights? hnRNP A1 displaces U2AF from uridine-rich RNAs not followed by a 3′ splice site AG ? A 3′ splice site AG allows formation of a ternary complex with hnRNP A1 and U2AF ? AG proofreading requires U2AF35 and the glycine-rich domain of hnRNP A1 ? hnRNP A1-mediated proofreading influences U2 snRNP recruitment
