The pre-mRNA and SF3b155 are located in the head domain of the B complex. (A) Comparison of the mapped position of the three pre-mRNA positions and SF3b155, as indicated. The likely location of components of the A complex and the tri-snRNP (see Discussion) are indicated. (B) Interpretative model of the position of the pre-mRNA in the B complex head domain. SF3b155 and its binding partners, p14 and U2AF65, are shown schematically. GU sequence represents the 5′ splice site, AG the 3′ splice site and A the branch site.
