Effects of Coding Flank Sequence. As shown before, recombination in cells with a mutant form of RAG1 (called D32) displays a strong preference for certain coding flank sequences over others (Sadofsky et al. 1995). Surprisingly, a very similar coding flank preference has been observed in cleavage at a single RSS by nonmutant RAG1 …The observed diversity of flanking sequences is likely to continue to increase and manual curation of naming schemes will be arduous to maintain. MEFinder, however, is a quick screening tool that can search a large library of known mobile elements but lacks sequence-level resolution.

The influence of flanking sequences on DNA-binding affinity was analyzed one flank at a time. Thus, to assess the influence of the 5′-flank, the position of the consensus sequence in the k-mer was fixed and all possible combinations (A, C, G or T) of 5′ flanks were considered.

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.
