Regulation of Kvα1.5 and Kvα1.5ΔC currents by Kvβ3

		Vh act (mV)	Time to peak act (ms)	Act time constant	Vh inact (mV)
Kvα1.5WT	alone	−6.5 ± 0.26	62 ± 14	1.7 ± 0.3	--a
	+β3	−19.7 ± 0.6*	7.1 ± 0.5*	1.5 ± 0.4	−22.2 ± 0.9
Kvα1.5ΔC56	alone	−3.2 ± 0.6†	22 ± 4.4†	1.1 ± 0.2	--a

^aDue to minimal inactivation, the kinetics and the voltage-dependence of inactivation of Kvα currents could not be reliably estimated
