Table 1.

Residues relevant to gating ring function reported in the literature

Equivalent amino acid numbers are shown for A. californica (Aplysia Slo1), mouse (mBK), and human BK (hBK). Table rows are color coded according to residue location: S6 (red), Mg²⁺-binding site (orange), RCK1 Ca²⁺-binding site (gray), and Ca²⁺ bowl (blue). Sequence alignment was performed using the Clustal Omega tool from EMBL-EBI and the following protein sequences: A. californica high conductance calcium-activated potassium channel (GenBank accession no. AAR27959 .1), Mus musculus mbr5 mslo (GenBank accession no. AAA39746 .1), and Homo sapiens calcium-activated potassium channel subunit α-1 isoform b (GenBank accession no. NP_002238 .2).
