<p>(K<sub>V</sub>): This family contains almost 40 members, which are further divided into 12 subfamilies. These channels are known mainly for their role in repolarizing the cell membrane following <a href="page.php?w=action_potential">action potential</a>s.  The ? subunits have six transmembrane segments, homologous to a single domain of the sodium channels.  Correspondingly, they assemble as <a href="page.php?w=tetramer_protein">tetramer</a>s to produce a functioning channel.<br/>
