Gene Gene information from NCBI Gene database.
Entrez ID 3736
Gene name Potassium voltage-gated channel subfamily A member 1
Gene symbol KCNA1
Synonyms (NCBI Gene)
AEMKEA1HBK1HUK1KV1.1MBK1MK1RBK1
Chromosome 12
Chromosome location 12p13.32
Summary This gene encodes a voltage-gated delayed potassium channel that is phylogenetically related to the Drosophila Shaker channel. The encoded protein has six putative transmembrane segments (S1-S6), and the loop between S5 and S6 forms the pore and contains
