In conclusion of this section, it is important to underline that the recruitment of nonhomologous crystallin genes occurred by independent changes in their promoters and enhancers, resulting in their gaining affinity for transcription factors that are members of the conserved developmental network used for eye and lens development in all species that have been studied.
These authors suggested that the MID domains of certain eukaryotic AGOs (that is, those involved in miRNA-mediated gene regulation) contain a second nucleotide-binding site in addition to the 5′-phosphate-binding pocket, which gains affinity for mGpppG cap analogues (or eventually for other ligands) only in the presence of the guide-strand RNA (and vice versa).
The target protein was gained by affinity chromatography on the column with Ni-NTA agarose, exploiting the interaction of Ni2+ ions and fusion histidine tag of the isolated protein.
Furthermore, SPR data revealed the conservation of antigenicity; if, on one hand, anti-BthTX-I/BPB loses affinity for immobilized BthTX-I, the same anti-BthTX-I/BPB gains affinity for immobilized BthTX-II.
Upon exposure to foreign antigens, precursor B cells undergo affinity-based selection and hypermutation of variable domains to gain in affinity and proliferate — a process termed affinity maturation.
Smads have low affinity for DNA and interact with DNA-binding cofactors to gain high affinity and selectivity for specific target genes [ 37].
However, the most encouraging results have been obtained with compounds that avoid targeting the zinc but gain their affinity from plunging deeper into the MMP S1′ cavity.
"The idea is to really gain an affinity not just with the print readers we have, but with a wider group of people who come to the site but are not making any kind of contribution".
It should be possible to gain additional affinity by accessing an additional local binding interaction or filling a local hydrophobic pocket by using a structure-based design approach.
In our data, the glycans at Asn276 could be relatively more flexible, and bnAbs might need special features to gain adequate affinity to different glycans at this glycosite.
