Large conductance calcium- and voltage- gated potassium (BK) channels are important regulators of physiological homeostasis and their function is potently modulated by protein kinase A (PKA) phosphorylation. PKA regulates the channel through phosphorylation of residues within the intracellular C-terminus of the pore-forming α-subunits. However, how PKA phosphorylation of the α-subunit effects changes in channel activity are unknown...
