"Intracellular calcium at nanomolar concentrations inhibits eag1 currents through calmodulin binding to the eag1 C-terminus [46] , the binding is calcium dependent with an apparent K D of 480 nM."

"HEAG1 Channels Lacking the PAS-cap Are Potentiated Rather than Inhibited by Ca 2+ i."

reach
"Within the channels discussed here, Ca -CaM inhibits Eag1 (Kv10) and TRPV5/6 channels, activates SK channels, and inhibits or activates Kv7 channels depending on other factors.Among ion channels, those that selectively allow the passage K ions display the largest diversity."

reach
"XREF_BIBR reported that the inhibition of hEAG1 by Ca 2+ was mediated by the direct binding of Ca 2+ / CaM to the C-terminus (AA 707-726) of the channel."

reach
"Kv10.1 channels are strongly inhibited by Ca /calmodulin , reactive oxygen species , and the phospholipid PIP , and there exists the possibility that more potent endogenous modulators remain to be discovered."

reach
"Consistently, by visualizing the interaction between YFP labeled CaM and Cerulean labeled hEAG1 in mammalian cells by Forster resonance energy transfer (FRET), Goncalves et al. [XREF_BIBR] found that the high affinity BD-N binding domain and the second C-terminal binding domain BD-C2 are predominantly involved in EAG1 channel inhibition by Ca 2+."

"In conclusion, Procyanidin B1 is a small molecule inhibitor of the Kv10.1 channel, with a potent inhibitory effect on the Kv10.1 channel in a concentration-dependent manner.Studies have shown that the[MISSING/INVALID CREDENTIALS: limited to 200 char for Elsevier]"
