The authors suggested that the S267E mutant altered the charge of the Fc, potentially increasing ionic interactions with the C1q subunit B. Among the four human IgG subclasses, IgG3 has the most potent CDC activity (Tao et al., 1993).
In contrast, co-expression of Ostm1 with the G213R mutant altered the ClC-7 localization significantly.
Surprisingly, we found that none of the mutations, including the full KKEKGKK deletion mutant, altered the spatial distribution of the receptor or frequency of cells expressing the receptor on the nuclear membrane (as assessed by lamin A/C colocalization) relative to the non-mutated receptor (Fig. 3B, data shown for the full putative NLS deletion mutant only).
We have previously shown that the β3-[C24A]-EGFP mutalteredered the voltage-dependency of inactivation for Nav1.5 (20).
Having characterized VN1203-WT dynamics, we were now able to determine how each specific VN1203 mutant altered the kinetics of the host responses.
As illustrated in Figure 1C-i and ii, the ectopic expression of RhoC and its mutant altered the tumour growth properties of CaSki and SiHa cells.
Indeed, the replacement of the neutral side chain by the negatively charged one in PpcAM58D mutant altered the reduction potential of haem III in a way that this haem is no longer the last one to oxidize.
However, the role of the Toll pathway as a antiviral response remains uncertain because previous studies have shown that Toll pathway genes are not up-regulated by DCV infection [11], and not all Toll pathway mutants alter the flies' susceptibility to DXV [13].
Although their expression does not change the total levels of peripherin (Fig. 7), CMT2B-causative RAB7A mutants alter the peripherin soluble/insoluble ratio (Fig. 8), suggesting that the process of peripherin filament assembly is at least in part compromised.
To assess whether differences in the total OMC composition of ppk mutants alter the invasion of INT-407 cells by the C. jejuni WT strain, INT-407 cells were exposed to total OMC extracts from WT, Δppk1, or Δppk2 prior to challenge with C. jejuni WT.
