Once all AOTEMPO is consumed, oligomerization of pendant acrylate groups generates crosslinks by a kinetic chain process that requires relatively few initiating radical species, owing to the efficiency of acrylate polymerizations.
52,53) By binding to BCL2, BCL-XL, and BCL-W with high affinity, these compounds competitively displace the sequestered BH3 domain-containing activator proteins and allow them to catalyze the oligomerization and activation of the proapoptotic effector proteins BAX and BAK and induce cell death (Figure).
The rare form seems to be the one that is regulated, and it seems to act like a seed for the initial oligomerization, which pulls in copies of the more abundant form," Si says.
In addition to the core cytolysin domain involved in assembly and membrane-spanning, VCC has an N-terminal pro-domain that locks the oligomerization domain in an inactive conformation and two contiguous lectin domains at the C-terminus (13).
It would then be possible to take the butanol and turn it into hydrocarbon jet fuel through oligomerization, a chemical process which strings together multiple butanol units to form molecules of the fuel.
N-Truncated A[beta] has been described in 35% of AD patients, based on immunoreactivity toward specific monoclonal antibodies (mAbs) (9); these truncated forms represent more than 60% of all A[beta] species and function as a nucleus for A[beta] oligomerization and deposition into neuritic plaques (8).
Hemosol's first technology involves the cross-linking and oligomerization of human hemoglobin with oxidized raffinose, a complex sugar molecule.
The goal of the funded study is to develop pharmaceuticals that can inhibit alpha-synuclein oligomerization and thus Lewy body formation and neurodegeneration.
Previous authors have emphasized the difficulty of measuring clones of FLCs, as their structures are heterogeneous and can be modified through pH, polymerization, and oligomerization (5-8).
Whatever the case, human synthetic NT-proBNP is a monomer, and the potential confounding issue of analyte oligomerization is not a problem for this analyte.
This may be related to the fact that the sequences of proANP and proBNP contain leucine zipper-like motifs, which might induce oligomerization (15).
Another study demonstrated that the N-terminal region of proBNP contains a leucine zipper-like sequence motif that may induce peptide oligomerization in plasma under physiologic conditions, producing either a trimer or tetramer of proBNP and a trimer of NT-proBNP (2).
