Recent analysis of MatK binding to intron substrates using RIPchip assays has identified the intron within trnK UUU) as a primary target for MatK maturase activity [ 2].
3D contour maps generated from the two models along with docking binding structures have identified several key structural requirements responsible for the activity.
The NPSR was found to display high-affinity saturable and displaceable binding of NPS in the subnanomolar range [1], [8], and structure-activity and conformation-activity studies have identified key residues for biological activity of the receptor [9], [10].
Recent work has identified eight cellular micro RNAs (miRNA) which are induced by interferon β and have potential binding sites in the HCV genome; some of these miRNAs have anti-viral activity against HCV in cell culture [17].
The present study has identified HDAC3 as an important carrier for the transport of TR2 phosphorylated specifically in its DNA-binding domain to PML NBs, a key step in the conversion of TR2's activity.
Initial studies focusing on the DNA binding and transcriptional activities of the ZAS proteins have identified several ZAS target genes involved in growth, immunity, and development, including interferon-β [5], collagen type II [6], somatostatin type II receptor [7], c-myc [8], and S100A4/mts 1 [4.
AnnA2, a cofactor for plasmin generation and cell-surface localization of fibrinolytic activity, has been identified as a receptor mediating β2GPI binding to ECs.
Multiple factors, among which we have identified decreased Sp1 binding, a local decrease in acetylation activity, and enhanced synthesis and recruitment of a repressor histone demethylase, alter the chromatin configuration over the promoter, ultimately blocking its activation by c-jun.
We have identified heparin binding domains that mediate the interaction of heparanase with its HS substrate and demonstrated that a peptide corresponding to Lys158-Asn171 (KKDC), inhibits heparanase enzymatic activity [29].
Now, we have identified a F3 binding motif in the BBK32 Fn-binding segment.
Our studies have identified several compounds with inhibitory activity (IC50) and binding affinity (KD) of ∼5 10 μM against the Zika NS2B-NS3 protease from testing 71 HCV NS3/NS4A inhibitors that were initially discovered by high-throughput screening of 40,967 compounds.
