Intron Dynamics in Ribosomal Protein Genes
The role of spliceosomal introns in eukaryotic genomes remains obscure. A large scale analysis of intron presence/absence patterns in many gene families and species is a necessary step to clarify the role of these introns. In this analysis, we used a maximum likelihood method to reconstruct the evolution of 2,961 introns in a dataset of 76 ribosomal protein genes from 22 eukaryotes and validate...
متن کاملA multigene family of intron lacking and containing genes, encoding for mouse ribosomal protein L7.
Mouse ribosomal protein L7 is encoded by a multigene family. Screening of two mouse genomic libraries with cloned L7 cDNA, has resulted in the isolation of nine independent lambda Charon 4A recombinant phages which include seven different L7 genes. Restriction enzyme mapping of six of these genes (L7-1, L7-16, L7-18, L7-28, L7-35 and L7- 16b ) reveals dissimilarity in sites within the L7 sequen...
متن کاملAnalysis of Ribosomal Protein Gene Structures: Implications for Intron Evolution
Many spliceosomal introns exist in the eukaryotic nuclear genome. Despite much research, the evolution of spliceosomal introns remains poorly understood. In this paper, we tried to gain insights into intron evolution from a novel perspective by comparing the gene structures of cytoplasmic ribosomal proteins (CRPs) and mitochondrial ribosomal proteins (MRPs), which are held to be of archaeal and...
متن کاملTranscriptional regulation in eukaryotic ribosomal protein genes.
Understanding ribosomal protein gene regulation provides a good avenue for understanding gene regulatory networks. Even after 5 decades of research on ribosomal protein gene regulation, little is known about how higher eukaryotic ribosomal protein genes are coordinately regulated at the transcriptional level. However, a few recent papers shed some light on this complicated problem.
متن کاملMany Ribosomal Protein Genes Are Cancer Genes in Zebrafish
We have generated several hundred lines of zebrafish (Danio rerio), each heterozygous for a recessive embryonic lethal mutation. Since many tumor suppressor genes are recessive lethals, we screened our colony for lines that display early mortality and/or gross evidence of tumors. We identified 12 lines with elevated cancer incidence. Fish from these lines develop malignant peripheral nerve shea...
