This led to the assumption that ACA may either obstruct site-specific phosphorylation through a direct interaction with IKK, or modulate further upstream signalling kinases such as MEKK3, TAK1 and NIK [ 40, 41].
Outcome measures: Immediate, short term, intermediate and long term relief of respiratory symptoms, feeding difficulties, effect of associated anomalies on outcome, effect of specific anatomic obstructing site and surgical procedure performed on outcome, and the incidence of complications inherent to the procedure.
[Metroblogging NYC] Concern that the landscaping planned for the new F.D.R. memorial on Roosevelt Island will obstruct the site's panoramic views.
Therefore, a major mechanism in the dimerization-induced activation of plexin appears to be the outward shift of the activation segment, which opens the otherwise obstructed active site to allow Rap binding and catalysis of GTP hydrolysis.
Drugs that induce protein degradation are likely to have different pharmacological effects from those that simply obstruct a binding site, as kinase-independent signalling will also be eliminated.
For example, the tomato (Solanum lycopersicum) SISBT3 possesses a potentially auto-inhibitory beta-hairpin domain that may obstruct the active site of the monomeric enzyme.
In addition to binding to the surface of the protease, the N-terminal region in TbMCA2 was found to obstruct the active site by forming hydrogen bonds with residues in the S1-binding pocket.
This endoproteolytic event in presenilin is thought to cut and remove a helix that otherwise obstructs the active site in the immature enzyme [33].
The latter orientation obstructs the binding site for Cc, because of the barrier imposed by the lipid bilayer.
After clipping of the coat and placement of the sheep head in the C-clamp, the fiducial marker post was fixed on the frontal bones caudal to one of the zygomatic processes to ensure that the registration markers were in different planes and not obstructing the surgical site.
The exclusion criteria were as follows: age younger than 20 years, separated bile duct due to hilar obstruction, bile duct obstructed at multiple sites, liver failure, contrast medium allergy, previous Billroth II gastrectomy or Roux-en-Y reconstruction, pregnancy, or refusal to provide informed consent.
