These results suggest that there is sign epistasis between the two alleles and that the high frequency TT haplotype represents a refining/fine-tuning adaptation, since recruitment of MSL complex to the adjacent MSL recognition motif is increased.
The restriction-site associated DNA (RAD) technique is capable of sequencing the regions adjacent to recognition site of a chosen restriction enzyme and widely applied to detecting single nucleotide polymorphisms (SNPs), even insertions/deletions (InDels), for quantitative trait locus (QTL) or evolutional analysis [ 5– 8].
Moreover, the genome-targeting scope has been increased by using staphylococcus aureus CRISPR/Cas9 (SaCas9) with modified protospacer adjacent motif (PAM) recognition (Kim et al., 2017b).
The Cas9 proteins are type II CRISPR-associated, RNA-guided DNA endonucleases that identify double-stranded DNA targets by sequence complementarity and protospacer adjacent motif (PAM) recognition.
Using an efficient computational model, we provide an extensive library of possible linker molecules between individual zinc finger motifs in the construct that can skip up to 10 base pairs between adjacent zinc finger recognition sites in the DNA sequence, which increases the number of genes that can be efficiently targeted by more than an order of magnitude.
Since the sequence-specificity of Tcf/Lef is relatively low, it generally binds its target sites in cooperation with other transcription factors that bind near or adjacent the Tcf/Lef recognition sequence [24], [38].
Additionally, they have identified an important surface in substrate recognition, adjacent to the conjugation active site on a SUMO E2 enzyme, UBC9, which has also high flexibility in the picosecond to nanosecond and microsecond to milisecond time scales [ 28].
Correspondingly, as illustrated in Figure 1A, a typical approach to construct a directionally cloned cDNA library leaves an adapter/linker sequence immediately adjacent to specific recognition site(s) for restriction endonuclease.
I've based my informational scheme of the cell on this thinking of "distinction on the adjacent" -- where molecular recognition is the essential phenomenon over which biological complexity has been developed.
