Positive control of pre-mRNA splicing in vitro

M Tian and T Maniatis

Department of Biochemistry and Molecular Biology, Harvard University, Cambridge, MA 02138.

Positive control of the sex-specific alternative splicing of doublesex (dsx) precursor messenger RNA (pre-mRNA) in Drosophila melanogaster involves the activation of a female-specific 3' splice site by the products of the transformer (tra) and transformer-2 (tra-2) genes. The mechanisms of this process were investigated in an in vitro system in which the female-specific 3' splice site could be activated by recombinant Tra or Tra-2 (or both). An exon sequence essential for regulation in vivo was shown to be both necessary and sufficient for activation in vitro. Nuclear proteins in addition to Tra and Tra-2 were found to bind specifically to this exon sequence. Therefore, Tra and Tra-2 may act by promoting the assembly of a multiprotein complex on the exon sequence. This complex may facilitate recognition of the adjacent 3' splice site by the splicing machinery.
