Nonconsensus branch-site sequences in the in vitro splicing of transcripts of mutant rabbit beta-globin genes

R A Padgett et al. Proc Natl Acad Sci U S A. 1985 Dec.

Abstract

Mutants of the rabbit beta-globin gene lacking the natural site of branch formation in the second intervening sequence have been analyzed for in vitro splicing activity. RNAs transcribed from these mutants were spliced, via lariat formation, at a reduced rate compared to wild-type RNA. The sites of branch formation were mapped by direct RNA analysis and primer-extension analysis. The sequences at the branch sites in the three mutants examined did not conform to the previously determined consensus sequence, nor were the 5' splice sites and branch sites complementary.
