"Since slo1 proteins often associate with various β subunits to form BK channels in vivo ( xref ; xref ; xref ; xref ; xref ; xref ; xref ; xref ; xref ) and it is known that β1 and β2 subunits affect apparent Ca 2+ sensitivity of the channel ( xref ; xref , xref ; xref ; xref ; xref ; xref ; xref , xref ; xref ; xref ; xref ), it will be interesting to examine if Mg 2+ -dependent activation is also affected by β subunits."

"To determine whether BK β1 TM1, TM2 or both are critical to provide the characteristic ion current phenotype of BK β1-containing BK channels, we combined surface protein biotinylation assays with patch-clamp studies under wide voltage and Ca 2+ i ranges (which included the values found in the SM myocyte under physiological conditions) on heteromeric BK complexes resulting from the association of rat cerebral artery SM slo1 (“cbv1”) with engineered BK β1."

"(5) While the authors have improved the definition of hetero-clusters etc it is still not clear in superesolution analysis, how they separate a BK tetramer from a cluster of BK tetramers with the monoclonal antibody employed ie each BK channel will have 4 binding sites (4 subunits in tetramer) whereas Cav1.3 has one binding site per channel."
