The ability of KCNQ (Kv7) channels to form hetero-oligomers is of high physiological importance, because heteromers of KCNQ3 with KCNQ2 or KCNQ5 underlie the neuronal M-current, which modulates neuronal excitability. In KCNQ channels, we recently identified a C-terminal subunit interaction (si) domain that determines their subunit-specific assembly. Within this si domain, there are two motifs that comprise approximately 30 amino acid residues each and that exhibit a high probability for coiled… CONTINUE READING
