Abstract. 7S RNA sequences from the hagfish (Myxiniformes) and lamprey (Petromyzontiformes) were cloned and analyzed. In both species, 7S L RNA (also designated SRP RNA, since it represents the RNA constituent of the signal recognition particle) was clearly detectable. The sequence similarity between the two species was 86%, compared with about 75% similarity between either of these species and mammals. 7S K RNA was also cloned from the lamprey. The similarity between the 7S K RNA of the… 

An alternative D. melanogaster 7SK snRNP

It is proposed that two distinct 7SK genes might contribute to the formation of the 7SK snRNP complex in D. melanogaster and it is shown that, like dm7SK, this alternative 7SK interacts in vivo with the different partners of the P-TEFb complex.

Evolution of 7SK RNA and its protein partners in metazoa.

An improved secondary structure model of 7SK RNA is derived, which shows that the structure is quite well-conserved across animal phyla despite the extreme divergence at sequence level.

Arthropod 7SK RNA.

This work reports on the discovery of arthropod 7SK RNAs using a novel search strategy based on pol III promoters, as well as the subsequent verification of its expression.

Invertebrate 7SK snRNAs

A combined experimental and computational survey succeeded in discovering 7SK RNAs in most of the major deuterostome clades and in two protostome phyla: mollusks and annelids, and confirming the evolutionary conservation and hence functional importance of the previously described 3′ and 5′ stem-loop motifs.

Family ties: molecular phylogenetics, evolution and radiation of flatworm parasites (Monogenea: capsalidae).

The Capsalidae is shown to be monophyletic, with the sister group remaining unresolved, and the Monopisthocotylea and the evolution of diet across the Neodermata are hypothesised to represent the first shift to parasitism in the NeODermata from a free living ancestor.

Evolution of the Neuropeptide Y System in Vertebrates with Focus on Fishes

It is concluded that the Hox cluster duplications involved a large number of adjacent gene families, supporting expansion of these families in the 2R, as well as in the teleost 3R tetraploidization.

Molecular phylogeny of early vertebrates: monophyly of the agnathans as revealed by sequences of 35 genes.

This work uses the sequences of 35 nuclear protein-encoding genes to provide definitive evidence for the monophyly of the Agnatha (jawless vertebrates, a group encompassing the hagfishes and lampreys).

Identification à l'échelle génomique de gènes transcrits par deux isoformes de l'ARN polymérase III humaine

Genome wide localization of RPC32α and RPC32β subunits of Pol III revealed the presence of bothsubunits on many of the known Pol III-transcribed genes, suggesting redundant activities of bothisoform-specific target genes in transcription of these genes, and led to the identification of novel Pol III candidategenes in HeLa cells.

Detailed secondary structure models of invertebrate 7SK RNAs

A systematic homology search extended the collection of 7SK genes in both Arthropods and Lophotrochozoa making use of the large number of recently published invertebrates genomes to infer complete consensus structures for invertebrate 7SK RNAs.



Evidence from 18S ribosomal RNA sequences that lampreys and hagfishes form a natural group.

Phylogenetic comparisons of 18S ribosomal RNA sequences from two hagfishes, two lampreys, a tunicate, a lancelet, and a number of gnathostomes support the monophyly of the cyclostomes, forcing a reassessment of several features of early vertebrate evolution.

Complete sequence of the amphioxus (Branchiostoma lanceolatum) mitochondrial genome: relations to vertebrates

The complete nucleotide sequence of the mitochondrial DNA of the amphioxus Branchiostoma lanceolatum has been determined, and the notion that prochordates may be viewed as the brother group of vertebrates is reinforced.

Structural analyses of the 7SK ribonucleoprotein (RNP), the most abundant human small RNP of unknown function

The human 7SK ribonucleoprotein (RNP) has been analyzed to determine its RNA secondary structure and protein constituents, and the possibility that the 7SK RNP is an unrecognized component of the pre-mRNA processing machinery is discussed.

Primary and secondary structure of 7-3 (K) RNA of Novikoff hepatoma.

The complete nucleotide sequence of 7-3 RNA was determined by RNA-sequencing methods, and the sequence is compared with several small RNAs and repetitive DNA sequences for homology.

Faithful in vitro transcription by fission yeast RNA polymerase III reveals unique alpha-amanitin sensitivity.

Results demonstrate that in contrast to the yeast Saccharomyces cerevisiae, pol III from S. pombe is sensitive to high concentrations of alpha-amanitin, yet with a clearly different dose response than that observed with the corresponding RNA polymerase of higher eukaryotes.

A subset of yeast snRNA's contains functional binding sites for the highly conserved Sm antigen.

The hypothesis was tested that yeast also contains functional analogues of Sm snRNA's, but that the Sm binding site in the RNA is more strictly conserved than the Sm antigenic determinant.

7SL RNA from Schizosaccharomyces pombe is encoded by a single copy essential gene

We have identified an abundant ribonucleoprotein particle from Schizosaccharomyces pombe with properties related to those of the vertebrate signal recognition particle (SRP), including cytoplasmic

Among the major players in the functioning of present-day eukaryotic cells are small complexes consisting of RNA and protein. Small ribonucleoprotein (RNP) particles, defined as tight complexes

Saccharomyces cerevisiae has a U1-like small nuclear RNA with unexpected properties.

Several regions of significant homology to U1 have now been found in cloned and sequenced snR19, and ten out of ten matches to the 5' end of U1, the site known to interact with the5' splice site of mammalian introns, are found.
