The magnitude of inhibition was neither voltage-dependent nor influenced by the nature of permeant ion.
2
By using a membrane-permeant fluorescent calcium probe, we observed that the acrosome actually behaves as a calcium store.
3
Anions and divalent cations did not pass the channel, but Na+ and K+ were equally permeant.
4
Vacuoles originate from this compartment in a rab7-dependent process and swell because they are acidic and accumulate membrane-permeant amines.
5
It was linked to frequency of DNA strand breaks and increased markedly during apoptosis induced by a cell-permeant glyoxalase I inhibitor.
6
Here, we use the gap junction-permeant tracer Neurobiotin to determine the architecture and coupling pattern of alpha cells in the mouse retina.
7
We found that injection of serotonin revealed significantly more intercellular communication than that injection of the most permeant synthetic tracer currently in use, neurobiotin.
8
The inhibition appears specific for Ca ions over other permeant divalent cations, and favors a possible physiologic role for the recently cloned Ca-inhibited adenylyl cyclase.
9
Moreover, because of its effects on open probabilities, the F380A mutant can be used for detailed voltage sensor experiments in the presence of permeant cations.
