These probes can be designed for high affinity binding to specific molecular targets and be used as tools in the early development of drugs, particularly for neuropsychiatric disorders.
Interestingly, optimization of zinc finger protein amino acid sequences for high-affinity binding to specific DNA sequences results in proteins with little or no predicted specificity, suggesting that naturally occurring DNA-binding proteins are optimized for specificity rather than affinity.
Immunoscopy is performed with the use of injected probes consisting of small molecules (enzyme substrates, receptor ligands, monoclonal antibodies, peptides) tagged to a fluorescent dye to achieve high-affinity binding to specific biochemical and molecular markers of disease [ 16].
The binding of ligand induces an activating conformational change within the ER, promoting dimerization and high-affinity binding to specific EREs (oestrogen-response elements) located within the regulatory regions of target genes [ 6].
In so far as osmotic regulation of TonEBP/OREBP by MDC1 depends on their physical association and the transcriptional activity of TonEBP/OREBP depends on its binding to specific DNA elements [3], [4] the high NaCl-induced reduction of the fraction of MDC1 that is bound to chromatin (Figure 3) appears paradoxical.
Leukocyte chemotaxis is initiated by the binding of chemotactic factors to specific, high-affinity receptors.
Since it is known that IFN γ mediates its effects by binding to a specific high-affinity receptor (Boehm et al, 1997), we asked whether the unresponsiveness of TGCT to the endogenous IFN γ is due to the lack or dysfunction of IFN γR on neoplastic germ cells.
Vitamin D is a steroid hormone that exerts most of its biological activities by binding to a specific high-affinity receptor, the vitamin D receptor (VDR).
Vitamin D exerts most of its biological activities by binding to a specific high-affinity receptor, the Vitamin D Receptor (VDR), that was first identified in a breast cancer cell line in 1979 [ 10].
Thus, these other modifications provide the framework in which Glu112 is able to mediate specific high affinity binding to xyloglucan.
