KCNMB4 Products

KCNMB4, also known as Calcium-activated potassium channel subunit beta-4, is a 210 amino acid protein that is 34 kDa; predominantly expressed in brain; regulatory subunit of the calcium activated potassium KCNMA1 (maxiK) channels which are fundamental to the control of smooth muscle tone and neuronal excitability; is an auxiliary beta subunit which slows activation kinetics, leads to steeper calcium sensitivity, and shifts the voltage range of current activation to more negative potentials than ...
