Taken together, the biochemical binding data and the functional data strongly suggest that NF90 is a specific dengue 3' SL binding protein that is a positive regulator of the dengue virus life cycle.
GAL4 is an 881-amino-acid protein with a Zn-Cys binuclear cluster type DNA-binding domain which is a positive regulator for galactose-induced gene expression [ 36].
Rabconnectin contributes to activation and deactivation of RAB3A, a small GTP-binding protein that is a positive regulator of vesicle mobilization and Ca2+ dependent exocytosis of neurotransmitter release at synaptic vesicles.
Three elements make up the PC binding site: the first is a positive patch located along the helix-turn-helix N-terminal domain of PsaF (Hippler et al., 1997, 1998; Ben-Shem et al., 2003).
In this study, the tumorigenic effects were strongly gene dose dependent, which would be expected if they depended on self-binding and clustering, which would be a positive power function (at least a square function) of cell surface molecular concentration.
DAP3, a proposed nucleotide binding protein, is a major positive regulator of apoptosis and has been shown to be critical for anoikis [ 68].
Similar positive binding was observed for positive control mAb hE16), but not for equivalent antisera from mice that were immunized with PBS).
Moreover, the idea that some DSX regions involved in dimerization and DNA binding are under positive selection [ 99], suggests that the evolution of the DSX binding domains and the DSX binding sites may even go hand-in-hand.
This result indicates that the predicted binding site one is a false positive due to the lack of a conserved Watson-Crick match at the eighth nucleotide of the miRNA and is in total agreement with previous studies reporting that the presence of m8M decreased the possibility of false positive compared to the sole presence of the "seed" and of the anchoring adenosine [16], [53].
Vascular segments with high radiotracer binding were positive by lipid staining, while additional large lipid-rich vascular areas were not identified by SPECT.
