If the above model of the involvement of the ABCC2 transporter in the mode of action of Cry1 toxins is correct, we should not expect any decrease in toxin binding since the extracellular domains of the protein are not altered, and the intracellular deletion does not seem to appreciably affect the conformation of the rest of the protein.
However, the most direct evidence of the involvement of ABCC transporters in the mode of action of B. thuringiensis toxins in S. exigua is that resistant insects, but not susceptible controls, carried a mutated allele of the ABCC2 gene.
The transporter, now in robot mode, began moving around the stage and responding to the speakers' commands, like a good robot butler should.
In the rice genome, transporter families are grouped by mode of transport and energy-coupling mechanism into four types: ATP-dependent transporters, secondary transporters, ion channels, and unclassified transporters with unknown mechanisms of action.
Scharinger, C. et al. Platelet serotonin transporter function predicts default-mode network activity.
Transporters are divided into TC families based on their mode of transport, energy coupling mechanism, molecular phylogeny and substrate specificity (Saier, 2000).
This site cannot be occupied by the cognate substrate but only by amphetamines, which were proposed to induce a long-lasting channel-like mode in the transporter.
We investigated the participation of NCX in ATP-mediated MUC5AC secretion and Ca2+ signaling using KB-R9743, aNCXCX inhibitor that preferentially blocks the reverse Ca2+ influx mode of the transporter (Iwamoto et al., 1996).
Citrate release, which is the normal activity of pmCiC, from HEK cells transfected with pmCiC was also electrogenic and K+-dependent as measured electrophysiologically. Surprisingly, however, citrate uptake, which occurs against the normal working mode of the transporter, in pmCiC-transfected HEK cells was Na+-dependent.
Subsequent blockade of the GAT-2/3 transporters by SNAP-5114 in the presence of t-PDC further increased the intracellular [Na+] indicating that GABA transporters work in the reversed mode following EAAT activation.
