Ca channel inactivation is a key element in controlling the level of Ca entry through voltage-gated Ca channels. Interaction between the pore-forming a1 subunit and the auxiliary b subunit is known to be a strong modulator of voltage-dependent inactivation. Here, we demonstrate that an N-terminal membrane anchoring site (MAS) of the b2a subunit strongly reduces a1A (CaV2.1) Ca 21 channel inactivation. This effect can be mimicked by the addition of a transmembrane segment to the N terminus of… CONTINUE READING
