Retrotransposons and Tandem Repeat Sequences in the Nuclear Genomes of Cryptomonad Algae

Journal of Molecular Evolution, 2007
The cryptomonads are an enigmatic group of unicellular eukaryotic algae that possess two nuclear genomes, having acquired photosynthesis by the uptake and retention of a eukaryotic algal endosymbiont. The endosymbiont nuclear genome, or nucleomorph, of the cryptomonad Guillardia theta has been completely sequenced: at only 551 kilobases (kb) and with a

Detection and visualization of tandem repeats in dna sequences

IEEE Transactions on Signal Processing, 2003
One conspicuous feature of DNA is the extent to which nucleotide subsequences repeat in the genome. Several strongly repetitive tandem (or contiguous) repeats are known to be associated with genetic diseases, while weaker repetitive structures are thought to be representative of historical events associated with sequence repetition.

Tandem sequence repeats in transmembrane channel proteins

Trends in Biochemical Sciences, 1991
The flow of ions and small molecules out of and between cells is mediated by various classes of transmembrane proteins. One group of putative channel proteins, including the abundant lens protein MIP, is widely distributed from prokaryotes to vertebrates.

Tandem repeats in proteins: From sequence to structure

Journal of Structural Biology, 2012
The bioinformatics analysis of proteins containing tandem repeats requires special computer programs and databases, since the conventional approaches predominantly developed for globular domains have limited success. Here, I survey bioinformatics tools which have been developed recently for identification and proteome-wide analysis of protein repeats ...

Sequencing and characterizing short tandem repeats in the human genome

Nature Reviews Genetics
Short tandem repeats (STRs) are highly polymorphic sequences throughout the human genome that are composed of repeated copies of a 1-6-bp motif. Over 1 million variable STR loci are known, some of which regulate gene expression and influence complex traits, such as height.

Greedily assemble tandem repeats for next generation sequences

International Journal of High Performance Computing and Networking, 2019
Eukaryotic genomes contain high volumes of intronic and intergenic regions in which repetitive sequences are abundant. These repetitive sequences represent challenges in genomic assignment of short read sequences generated through next generation sequencing and are often excluded in analysis losing invaluable genomic information.

Detecting fuzzy amino acid tandem repeats in protein sequences

Proceedings of the 2nd ACM Conference on Bioinformatics, Computational Biology and Biomedicine, 2011
Tandem repetitions within protein amino acid sequences often correspond to regular secondary structures and formmulti-repeat 3D assemblies of varied size and function. Developing internal repetitions is one of the evolutionary mechanisms that proteins employ to adapt their structure and function under evolutionary pressure. While there is keen interest

Locating Tandem Repeats in Weighted Biological Sequences

2012
A weighted biological sequence is a string in which a set of characters may appear at each position with respective probabilities of occurrence. We attempt to locate all the tandem repeats in a weighted sequence. By introducing the idea of equivalence classes in weighted sequences, we identify the tandem repeats of every possible length using an ...

Short tandem repeat sequencing on the 454 platform

Forensic Science International: Genetics Supplement Series, 2011
Abstract To investigate the feasibility of next generation sequencing (NGS) technology for the multiplex detection and sequence production of short tandem repeats (STRs), thirteen STR markers (CSF1PO, D2S441, D3S1358, D5S818, D7S820, D8S1179, D10S1248, D13S317, D16S539, D21S11, D22S1045, TPOX, and vWA) were amplified using an optimized multiplex ...

Sequence variation of a hypervariable short tandem repeat at the D1S1656 locus

International Journal of Legal Medicine, 1998
A short tandem repeat at the D1S1656 locus was sequenced in 45 selected alleles and 13 different alleles were found which were designated according to the total number of repeats. This STR is a compound hypervariable STR consisting of blocks of (TAGR) repeats with a basic sequence structure (TAGA)4(TGA)0-1(TAGA)6-16(TAGG)0-1(TG)5. The presence of a TGA,
