Abstract excerpt
The functional diversity of large conductance Ca(2+)- and voltage-dependent K(+) (BK) channels arises mainly from co-assembly of the pore-forming mSlo alpha subunits with four tissue-enriched auxiliary beta subunits. The structural basis of the interaction between alpha subunits with beta subunits is not well understood. Using computational and experimental methods, we demonstrated that four mSlo turrets...
