Weba functional channel complex in which the b2 intracellular domain is in close contact with Na v1.5, we attached this b2 sequence to b11D resulting in b112. We expected that pos-sible functional effects of the b2 intracellular domain may become visible when the spatial requirements for an a/b2 interactionarefulfilled.Inthisstudy,weusedsucha b ... WebSep 12, 2024 · The intracellular PAS domains and CNBHDs interact directly and regulate some of the characteristic gating properties of each type of KCNH channel. The PAS-CNBHD interaction regulates slow closing (deactivation) of hERG channels, the kinetics of activation and pre-pulse dependent population of closed states (the Cole-Moore shift) in …
