name: voltage-gated potassium channel subunit KCNQ2 sequence variant S247W (human)
def: "A potassium voltage-gated channel subfamily KQT member 2 (human) that has a Trp residue at the position equivalent to Ser-247 of the amino acid sequence represented by UniProtKB:O43526-1. Example: UniProtKB:O43526-1, Ser-247, CHEBI:29954." [PRO:CNA, PRO:DAN, PMID:12742592]
comment: Category=organism-sequence. Note: This residue is located within the transmembrane S5. This form reduces the current amplitude of KCNQ2 homomeric channels in a dominant-negative manner whereas the amplitude of KCNQ2/KCNQ3 heteromers is only reduced by about 40%.
