The retinal waves were changed to activate neurons within a radius rR and the total retinal activity were normalized to maintain a constant level of activation for each wave.
The self-assembly between the effector and receptor site for either one of the input (A or B), might not be sufficient in triggering a conformational change to activate the ribozyme.
Many kinases are phosphorylated within this loop, which then undergoes a conformational change to activate the kinase and allow access to the substrate binding site.
Our findings also predict that there will be a ubiquitinPhospho−Ser65-binding pocket within the catalytic core of Parkin that would induce a conformational change to activate Parkin following the ubiquitinPhospho−Ser65 interaction.
When Sun and Chasin [2000] systematically studied the importance of various splicing regulatory elements (5′- and 3′-splice site strength in combination with splicing enhancer and silencer sequences) for their ability to cause inclusion of a pseudoexon from the human HPRT gene, they concluded that more than one element had to be changed to activate the pseudoexon.
The molecular architectures of several SMG1C-UPFs complexes, obtained by combining electron microscopy with in vivo and in vitro interaction analyses, competition experiments, and mutations, suggest that UPF2 can be transferred to UPF1 within SMG1C, inducing UPF2-dependent conformational changes required to activate UPF1 within an SMG1C-UPF1-UPF2 complex.
And, after all the country has been through over the last seven years, the times are definitely right for the message that the only way to get real change is to activate the American people to demand it".
In addition to the Bcl-xL checkpoint that prevents lethal levels of Bax accumulation on mitochondria, the composition of the outer membrane itself, namely cholesterol content may hamper the complete conformational change required to activate apoptosis.
These data indicate that 5-HT compounds are capable of overcoming components of age-related changes in physiology to activate POMC neurons and suppress feeding.
In many cases, only single base pair changes are required to activate, silence, or functionally alter critical genes (e.g., proto-oncogenes, tumor suppressor genes) in a cell type-, differentiation stage-, and carcinogen-specific manner.
