Regulation of maximal open probability is a separable function of Ca(v)beta subunit in L-type Ca2+ channel, dependent on NH2 terminus of alpha1C (Ca(v)1.2alpha).

The Journal of general physiology - 1 Jul 2006

Kanevsky Nataly, Dascal Nathan

Abstract excerpt

beta subunits (Ca(v)beta) increase macroscopic currents of voltage-dependent Ca2+ channels (VDCC) by increasing surface expression and modulating their gating, causing a leftward shift in conductance-voltage (G-V) curve and increasing the maximal open probability, P(o,max). In L-type Ca(v)1.2 channels, the Ca(v)beta-induced increase in macroscopic current crucially depends on the initial segment of the cytosolic...
