Funkcija

Porodica šejker gena u Drosophila kodira komponente naponski-vođeni kalijski kanal i sastoji se od četiri potporodice. Na osnovu sličnosti sekvenci, ovaj gen je sličan jednoj od ovih potporodica, odnosno podporodici šou. Protein kodiran ovim genom pripada klasi kanalnih proteina sa odloženim ispravljačem i integralni je membranski protein koji posreduje u naponsko zavisnoj permeabilnosti kalijevih jona ekscitabilnih membrana.^[6]^[7]^[8]

Klinički značaj

KCNC3 je povezan sa spinocerebelumskom ataksijom tipa 13.^[9]
