title: [Low molecular channel-former protein from the mitochondrial membrane].
abstract: Individual low molecular weight protein component was isolated by gel-filtration method from the inner mitochondrial membrane. This membrane component increases the conductivity of bilayer lipid membranes (BLM) in the presence of K+ and Ca2+-ions. This phenomenon may be explained by the formation of single conductivity channels. The voltage - current characteristics of this channel is nonlinear, which may be the result of asymmetrical operation of the channel - former in the polarized membrane, in spite of equal concentration of protein on both sides of the membrane.
