Sentence examples for mutations on channel from inspiring English sources

Here we report the channel opening (ko) and closing (kc) rate constants for 64 different mutations of nine αM2-cap residues in the mouse neuromuscular AChR (αI260-αS268), as well as the effects of these mutations on channel conductance, channel blockade and an approximate rate constant for entry into long-lived desensitized states.

The effects of many of these mutations on channel function have been characterized both in vitro and in vivo.

Schematic representation of detected changes is illustrated in Figure 4. To evaluate the possible influence of new missense mutations on channel function, bioinformatics analysis has been conducted.

Studying the effects of such mutations on channel function and relating these changes to clinical manifestations offers ample opportunities to study 'human biology'.

In contrast to E698, E701, E730, and D734 that display features consistent with their direct interaction with calcium and strontium ions, the effects of the E650 mutations on channel activation by strontium further support the notion that E650 is not directly involved in metal ion binding, as indicated by their effects on calcium sensitivity.

We thus speculate that the bacterial members of this superfamily of Mg2+ transporters act as channels, first because Mrs2 and Alr1 proteins apparently share structural features of their core sequences with CorA proteins (4) and second, because effects of mrs2 mutations on channel activity match very well predictions based on the crystal structure of CorA.

To characterize the effects of the novel mutation on channel function, mutant p.Gly263Asp was introduced into wild type human Kv3.3 [12].

The impact of the mutation on channel activity is most apparent in the high gain recordings, which reveal a marked increase in Na+ channel activity that has failed to inactivate completely over the duration of the 200 ms test pulse.

To estimate the effect of the Bdel1 mutation on channel Po, we used the method of Yue and coworkers that relies on the ratio of ionic to gating currents [28].

We therefore used a rat mutant construct to explore the effect of the novel mutation on channel function, in the same way we described previously for the MMPSI-linked R428Q and A934T mutations (31).

Our homology modeling raises an additional possibility for the influence of the L532P mutation on channel gating and drug binding to side chains that line the permeation pathway (e.g. residues on S6).
