This entry includes calcium-activated potassium channels, known as BK channels or Slowpoke homologues (Slo1-3) which includes calcium-activated potassium channel slowpoke from Drosophila (Slo) and its homologues from vertebrates KCMA1, KCNT1/2 and KCNU1. This entry represents the C-terminal regulator of K+ conductance (RCK) domains which appear as tandem domains in these proteins [1-5]. The RCK domain has a Rossmann-fold topology with unique positions that compose a well-conserved salt bridge and a hydrophobic dimer interface. This domain is also presents in prokaryotic K+ channels.
