title: Structural basis for autogenous regulation of Xenopus laevis ribosomal protein L1 synthesis at the splicing level.
abstract: It is known that the injection of the Xenopus laevis ribosomal protein L1 gene into oocytes causes the accumulation of immature L1 transcripts due to a specific block of splicing of the second and third introns. In this paper the secondary structures of these introns in pre-mRNA have been constructed. It has been shown that they share homology with 28 S rRNA. The putative RNA-binding segment of L1 has also been predicted. These results are interpreted as the structural basis for autogenous regulation of X. laevis ribosomal protein L1 synthesis at the splicing level.
