What are flanking sequences.

Beyond transcripts. Current HGVS recommendations state (see Reference Sequences): “5’ and 3’ flanking sequences are considered to be outside the boundaries of a transcript reference sequence and can not be used to describe variants”.As a consequence, variants removing an entire gene or the 5’ or 3’ end of a transcript can only be described using …Here, we examine two flanking sequences bordering a site in the γ-fibrinogen gene regulatory region that binds a heterodimer of the Xenopus glucocorticoid receptor accessory factor (XGRAF) and the glucocorticoid receptor (GR). Mutation of the upstream flank results in a decrease in XGRAF binding, but little change in hormone induction.In the process of comparing the read sequence and single motif, it is not needed for a priori assumptions on the repeat number, which is STRsearch’s advantage over the existing tool named STRScan. The actual STR region is determined by comparing the position of repeat patterns with the best matching location of flanking sequences in reads.Seamlessly parsing both FASTA and FASTQ formats.

Meslet-Cladière and Vallon (2012) determined the flanking sequences of 38 randomly selected insertion mutants in a transposon insertion mutation library of the model organism C. reinhardtii. These authors used the 3′ end of the RACE technique. Twenty-seven (71%) were valid flanking sequences, and 23 could be accurately localized in the genome.By using restriction enzymes specific for sites flanking the VNTR, fragments of variable lengths in different individuals can be obtained because each subject has a different number of repeats. Fragments can also be obtained and multiplied by PCR using primers complementary to the VNTR flanking sequences.Meslet-Cladière and Vallon (2012) determined the flanking sequences of 38 randomly selected insertion mutants in a transposon insertion mutation library of the model organism C. reinhardtii.

Furthermore, the putative insertion loci and flanking sequences were confirmed by PCR amplification and Sanger ...

Knowledge about the inserted sequences is an advantage over other mutagenesis methods, because localization of the insertion within the mutagenized genome based on the generation of flanking sequence tags (FSTs) is possible [5, 6].flanking sequence The untranscribed regions at the 5′ or 3′ ends of a transcribed gene. Source for information on flanking sequence: A Dictionary of Ecology dictionary. The term ‘flanking region’ usually refers to regions of the genome up to 103–104 bases on either side of the terminal exons of a gene, and which especially contain promoter and other regulatory sequences [99,100].

Exon circularization has been identified from many loci in mammals, but the detailed mechanism of its biogenesis has remained elusive. By using genome-wide approaches and circular RNA recapitulation, we demonstrate that exon circularization is dependent on flanking intronic complementary sequences. Such sequences and their …The observed upstream sequence motif and the patterns of sequence conservation flanking the stem–loop portion of the miRNA genes motivated us to develop an improved miRNA gene-finding algorithm, which we call MiRscanII.

The small directly repeated flanking sequences generated by insertion are shown as red arrows. The target sequence destined to become the new flanking repeat is indicated by white arrows. Transposition is initiated by cleavage at both terminal inverted repeats (marked 1 and 2) of the IS to generate 3’OH ends (small green circles) that attack ...The flanking sequences provided by dbSNP of NCBI are usually short and fixed length without further extension, thus making the design of appropriate PCR primers difficult. Here, we introduce a tool named “SNP-Flankplus” to provide a web environment for retrieval of SNP flanking sequences from both the dbSNP and the nucleotide databases of NCBI.
