Jonski kanal

Šematski prikaz jonskog kanala. 1 - kanalni domeni (tipično četiri po kanalu), 2 - spoljašnja pretkomora, 3 - filter selektivnosti, 4 - dijametar filtera selektivnosti, 5 - mesto fosforilacije, 6 - ćelijska membrana.

Jonski kanali su proteini koji formiraju pore koje pomažu u uspostavljanju i kontroli naponskog gradijenta preko ćelijske membrane (vidi ćelijski potencijal) putem omogućavanja protoka jona niz njihov elektrohemijski gradijent.^[1]^[2] Oni su prisutni u membranama koje okružuju sve biološke ćelije. Studiranje jonskih kanala obuhvata mnoge naučne tehnike kao što su elektrofiziologija naponske spone (posebno slojna spona), imunohistohemija, i RT-PCR.
