The C48A and C139A mutants of hPNMT, which are incapable of forming the disulfide bond observed in the crystal structure, have a decreased propensity to form dimer in solution.
These chelating ligands are based on the 1,4,7-triazacyclononane (TACN) structure and have been chosen to allow enhanced efficiency in protein capture and decreased propensity for metal ion leakage in the immobilized metal ion affinity chromatographic (IMAC) purification of recombinant proteins.
iPSCs derived from mouse neural progenitors, for example, contained methylomic signatures at loci important for hematopoietic differentiation, resulting in a decreased propensity for differentiating into hematopoietic cell types.
Therefore, it is conceivable that evolution would select for an overall decreased aggregation propensity in operons performing essential cellular functions.
Mutants 23G5 (V210I and A281E) and 195F1 (derived from 23G5 with one additional mutation, V221D) showed over a 20-fold increase in half-life at 70°C in comparison to the wild-type CalB, by decreasing mutants propensity to aggregate in the unfolded state.
Four other mutations also impaired the β-strand propensity but moderately: F3 triggering a stronger random coil propensity for A1; S8, S8 and K14 slightly decreasing the β-strand propensity in the YMVH region.
While one of these edges is to dampen ER signaling, the other three will lead to a decreased apoptosis propensity and increased proliferation propensity.
"Bolstering positive religious coping strategies may decrease students' propensity to engage in maladaptive coping such as addictive behaviors," the researchers noted.
Overexpression of Snail increased the motility of MCF-7, T-47D and MDA-MB-231 cells, whereas silencing of the protein resulted in decreased migratory propensity of MCF-7, MDA-MB-468 and MDA-MB-231 cells.
Inhibition of SEG neuronal activity could therefore, in principle, decrease the propensity for expression of spontaneously initiated walking-related behaviors.
Lesions of the PLC, in contrast, decreased the propensity to relapse when abstinent rats were returned to the drug-seeking environment.
