Consequently the regulatory binding site acts as a transponder for the whole cascade of events leading to regulatory complex binding or activation, for example a study in yeast found that trans acting eQTL were not enriched for transcription factors and that a wide range of gene classes could cause trans differences in expression [ 1].
In PMap the expression of markers of strong activation, for example, CD62P (P-selectin) and phosphatidylserine (annexin A5 binding), were increased in comparison to resting platelets.
Mechanisms of action of BAG-1 that do not occur through direct HSC70/HSP70 binding, for example, the activation of Raf-1 by BAG-1 are also likely to be important (Song et al, 2001).
Oxidized derivatives of cholesterol with biological activity, for example, as binding partners for nuclear receptors.
Another possibility was that a feedback signal arose from an earlier step in the activation of IP3R by IP3, a conformational change in the IP3-binding site, for example.
We note that position 5.47 has been found to be involved in agonist binding in other receptors; for example, it plays a role in the binding and activation of β2-adrenergic receptor agonists.
As a possible consequence of the increased openness could be the acceleration of alkali-activation process resulting, for example, in the acceleration of the strength development of binding system based on the thermally treated bentonite.
For example, activation of Xtwn requires Smad3 binding to the Smad binding elements (SBEs); c-myc activation needs Smad4 binding to the Lef/Tcf binding elements 1 (TBE1).
This mode of activation provides another possible pathway for regulating myofibroblast activity by blocking integrin binding to latent TGF-β1, for example by blocking the integrin involved in latent TGF-β1 activation, αvβ5.
Alternatively, CD47-induced activation of a PTX sensitive G-protein can arise through a trans interaction i.e. by binding of a specific ligand, for example thrombospondin, directly to CD47 [23].
