Using statistical mechanics, a random-binder model without fitting parameters, with genomic DNA sequence being the only input, we further validate that the nonconsensus nucleotide triplet code constitutes a key signature providing PIC binding specificity in the human genome.
Each of the aligned overlapping nonamer (9-mer) positions represent a possible antigenic core binding domain for human leukocyte antigen (HLA; human MHC) molecules and T-cell receptors [ 16, 17]; this assumption is based on the fact that there are large array of HLAs with different binding specificities in the human population [ 17].
The analysis by Tonikian et al. [7] established a predictive correlation between the domain sequence and binding specificity in organisms from worm to human.
Consistent with these findings, a designed "humanized" mutant of ecDHFR switches binding specificity in the cell.
Thus, a simple but reasonable prediction based solely on protein sequence would be that there should be significant divergence in binding specificity between human and Drosophila TFs.
Furthermore, although large systematic datasets exist for in vitro binding specificity of human and mouse TFs determined using protein-binding microarrays (Badis et al., 2009) and high throughput SELEX (HT-SELEX; Jolma et al., 2013), these methods have not been previously used to systematically analyze specificities of many TF families from more distantly related organisms.
Representing transcription factor binding specificities in this form means that no data is stored on the interaction of binding specificity between different base positions in the binding sites.
Competition study was designed to evaluate the amyloid plaque binding specificity using human brain tissues.
One major barrier limiting cross-species transmission into humans (and vice versa) is the evolution of differences in sialic acid linkage binding specificity between humans and birds and humans and primates (Rich et al. 2009).
The similarity in the binding specificities of human and mouse LSECtin suggested that, like the human protein, mouse LSECtin might be a target for binding to the surface glycoprotein of Ebola virus.
