Maintenance of heterochromatin by RNA interference of tandem repeats

, 2003
Tandem repeats are prone to epigenetic silencing regulated by RNA interference. This may be because siRNAs from tandem array transcripts are regenerated by RNA-dependent RNA polymerase (RdRP) and Dicer, but siRNAs from single-copy sequences are exhausted

Analysis of the largest tandemly repeated DNA families in the human genome

BMC Genomics, 2008
Background Tandemly Repeated DNA represents a large portion of the human genome, and accounts for a significant amount of copy number variation. Here we present a genome wide analysis of the largest tandem repeats found in the human genome sequence ...

De novo assembly of bacterial genomes with repetitive DNA regions by dnaasm application

BMC Bioinformatics, 2018
Background Many organisms, in particular bacteria, contain repetitive DNA fragments called tandem repeats. These structures are restored by DNA assemblers by mapping paired-end tags to unitigs, estimating the distance between them and filling the gap ...

Comparative genomics of amino acid tandem repeats [PDF]

, 2009
Tandem amino acid repeats, also known as homopolimeric tract or homopeptides, are very common features of eukaryotic genomes and are present in nearly one-fifth of human encoded proteins.

TReaDS: Tandem Repeats Discovery Service [PDF]

, 2008
Tandem repeats (TRs) are multiple duplications of substrings in the DNA that occur contiguously, or at a short distance, and may involve some mutations (such as substitutions, insertions, and deletions).

Protein tandem repeats - the more perfect, the less structured

, 2010
International audienceWe analysed the structural properties of protein regions containing arrays of perfect and nearly perfect tandem repeats. Naturally occurring proteins with perfect repeats are practically absent among the proteins with known 3D ...

Exactly periodic subspace decomposition based approach for identifying tandem repeats

, 2006
The identification and analysis of tandem repeats is an ac-tive area of biological and computational research. Tandem repetitive structures in telomeres plays a role in cancer and hyper-variable, trinucleotide tandem repeats are linked to over a dozen ...

Expansion and Function of Repeat Domain Proteins During Stress and Development in Plants

Frontiers in Plant Science, 2016
The recurrent repeats having conserved stretches of amino acids exists across all domains of life. Subsequent repetition of single sequence motif and the number and length of the minimal repeating motifs are essential characteristics innate to these ...

Filtering Tandem Repeats in DNA Sequences

, 2008
A tandem repeat is a sequence of two or more contiguous, approximate copies of a pattern. Tandem repeats occur in the genomes of both eukaryotic and prokaryotic organisms. They are important in numerous fields including disease diagnosis, mapping studies,

Tandem repeats as sources of variation

, 2014
Tandem repeats make up a small fraction of the human genome, but due to their high rates of expansion and contraction, they are predicted to be highly polymorphic.
