	'''Potassium channels''' (KCh) are subdivided into voltage-gated KCh and calcium-dependent KCh. The latter are subdivided into high- (BK, LKCa), intermediate- and small-conductance KCh (human SK1, rat SK2, SKCa). The T1 domain is a highly conserved N-terminal domain which is responsible for driving the tetramerization of the KCh α subunit. The inward rectifier KCh (IRK) passes current more easily in the inward direction. MthK is a calcium-dependent KCh from ''Methanobacterium thermoautrophicum''.
