[Term] id: PR:000000907 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%. synonym: "hKCNQ2/var:S247W" EXACT PRO-short-label [PRO:DNx] synonym: "UniProtKB:O43526, Ser-247, CHEBI:29954" EXACT PRO-proteoform-std [PRO:DAN] synonym: "voltage-gated potassium channel subunit KCNQ2 sequence variant 1 (human)" EXACT [PRO:DNx] synonym: "UniProtKB:O43526-1, Ser-247, CHEBI:29954" NARROW PRO-proteoform-std [PRO:DAN] xref: UniProtKB_VAR:VAR_026991 is_a: PR:O43526 ! potassium voltage-gated channel subfamily KQT member 2 (human) relationship: only_in_taxon NCBITaxon:9606 !
