The β1 and β3 subunits are noncovalently linked to the α subunit, whereas the β2 and β4 subunits are capable of forming a covalent disulfide linkage (not shown). For the family of Na+ channel α subunits, the current terminology (Table 2) indicates the permeant ionic species (Na) ...
A second alternative to explain the functional integrity of the splits is that the end of S4 and/or the beginning of the S4–S5 loop are used to transmit a conformational non-covalent coupling of the voltage sensor movement to opening and closing of the gate at the bundle crossing of S6 ...
