Abstract
A complementary DNA clone encoding the large subunit of the essential mammalian pre-messenger RNA splicing component U2 snRNP auxiliary factor (U2AF65) has been isolated and expressed in vitro. It contains two functional domains: a sequence-specific RNA-binding region composed of three ribonucleoprotein-consensus sequence domains, and an arginine/serine-rich motif necessary for splicing but not for binding to pre-mRNA.
