Primary Identifier | IPR001925 | Type | Family |
Short Name | Porin_Euk |
description | Eukaryotic mitochondrial porins are voltage-dependent anion-selective channels (VDAC) that behave as general diffusion pores for small hydrophilic molecules [, , , ]. The channel adopts an open conformation at low or zero membrane potential and a closed conformation at potentials above 30-40 mV.The proteins are composed of between 12 to 16 β-strands that span the mitochondrial outer membrane. Yeast contains two members of this family (genes POR1 and POR2); vertebrates have at least three members (genes VDAC1, VDAC2 and VDAC3) [, ]. |
