Interaction between human tRNA synthetases involves repeated sequence elements.

Seung-Bae Rho, K H Lee, J W Kim et al. · Proceedings of the National Academy of Sciences · 1996

Aminoacyl-tRNA synthetases (tRNA synthetases) of higher eukaryotes form a multiprotein complex. Sequence elements that are responsible for the protein assembly were searched by using a yeast two-hybrid system. Human cytoplasmic isoleucyl-tRNA synthetase is a component of the multi-tRNA synthetase complex and it contains a unique C-terminal appendix. This part of the protein was used as bait to identify an interacting protein from a HeLa cDNA library. The selected sequence represented the internal 317 amino acids of human bifunctional (glutamyl- and prolyl-) tRNA synthetase, which is also known to be a component of the complex. Both the C-terminal appendix of the isoleucyl-tRNA synthetase and the internal region of bifunctional tRNA synthetase comprise repeating sequence units, two repeats of about 90 amino acids, and three repeats of 57 amino acids, respectively. Each repeated motif of the two proteins was responsible for the interaction, but the stronger interaction was shown by the native structures containing multiple motifs. Interestingly, the N-terminal extension of human glycyl-tRNA synthetase containing a single motif homologous to those in the bifunctional tRNA synthetase also interacted with the C-terminal motif of the isoleucyl-tRNA synthetase although the enzyme is not a component of the complex. The data indicate that the multiplicity of the binding motif in the tRNA synthetases is necessary for enhancing the interaction strength and may be one of the determining factors for the tRNA synthetases to be involved in the formation of the multi-tRNA synthetase complex.

Sequence conservation of an avian centromeric repeated DNA component

Cort S. Madsen, Jonah C. Brooks, Edwin de Kloet et al. · Genome · 1994

The approximately 190-bp centromeric repeat monomers of the spur-winged lapwing (Vanellus spinosus, Charadriidae), the Chilean flamingo (Phoenicopterus chilensis, Phoenicopteridae), the sarus crane (Grus antigone, Gruidae), parrots (Psittacidae), waterfowl (Anatidae), and the merlin (Falco columbarius, Falconidae) contain elements that are interspecifically highly variable, as well as elements (trinucleotides and higher order oligonucleotides) that are highly conserved in sequence and relative location within the repeat. Such conservation suggests that the centromeric repeats of these avian species have evolved from a common ancestral sequence that may date from very early stages of avian radiation.

Repeated sequence markers in pea (<i>Pisum sativum</i>)

Lynda Turner, Noel Ellis · New Phytologist · 1997

summary Multiple‐marker techniques based on PCR are highly informative in genetic analysis. The bulk of many genomes is comprised of repeated sequences, and thus anonymous markers derived from genomic DNA are likely to correspond to repeated DNA sequences. Here we show that repeated‐sequence‐derived markers can provide information similar in quality to that of other PCR‐based markers. Presumably this reflects the abundance of this repeat type in anonymous PCR markers such as RAPDs or AFLPs.

Learning of a single chunk repeated in random sequence.

&lt;p&gt;&lt;b&gt;(a)&lt;/b&gt; Input sequence repeating a single chunk. In this example, the chunk is composed of four alphabets (a, b, c, d). The components and lengths of random sequences varied during the repetition of chunks. &lt;b&gt;(b)&lt;/b&gt; Example responses are shown for input neurons. &lt;b&gt;(c)&lt;/b&gt; In the dual RC model, two non-identical reservoirs are activated by the same set of input neurons. Readout weights of each RC system undergo supervised learning with a teaching signal given by the output of the partner network. &lt;b&gt;(d)&lt;/b&gt; and &lt;b&gt;(e)&lt;/b&gt; Pre- and post-learning trial averaged activities of a readout unit are shown, respectively. Shaded intervals designate the presentation periods of the chunk. The other readout unit exhibited a similar activity pattern. (&lt;b&gt;f&lt;/b&gt;) Readout activity was trained with many-to-one input projections. The fraction of input neurons projecting to a reservoir neuron was 10% (red), 40% (green) and 70% (black).&lt;/p&gt;

Isolation of a Repeated DNA Sequence from Bordetella pertussis

William L. McPheat, Teresa McNally · Microbiology · 1987

A repeated DNA sequence in the genome of Bordetella pertussis has been demonstrated. At least 20 copies of this sequence could be observed in either BamHI or EcoRI restriction enzyme digests of chromosomal DNA; fragments carrying the repeated DNA sequence ranged in size from about 1.5 to 20 kbp. The repeated DNA sequence was cloned from two separate regions of the B. pertussis genome, as shown by restriction enzyme site maps of the two clones and by hybridization studies. A small number of differences in the pattern of hybridization of the repeated DNA sequence to chromosomal DNA from several strains of B. pertussis was observed. No repeated DNA sequences were observed in one strain each of B. parapertussis and B. bronchiseptica, and there was no hybridization of B. pertussis DNA to Escherichia coli chromosomal DNA. The repeated DNA sequence was subcloned on a 2.54 kbp BamHI fragment from one of the two original clones. Restriction enzyme digests and hybridization studies showed that the repeated DNA sequence was about 1 kbp in size and had a single, internal ClaI site.
