A base-pairing interaction between U2 and U6 small nuclear RNAs occurs in > 150S complexes in HeLa cell extracts: implications for the spliceosome assembly pathway.

In mammalian cells, base pairing between the U2 and U6 small nuclear RNAs is required during pre-RNA splicing. We show by psoralen crosslinking of HeLa nuclear extract that U2.U6 base pairing occurs within abundant ribonucleoprotein complexes that sediment at > 150 S in glycerol gradients. All of...
