Application Abreviews Notes
WB 1/500 - 1/3000. Predicted molecular weight: 32 kDa.

  • Function

    Forms a channel through the mitochondrial outer membrane that allows diffusion of 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 open state has a weak anion selectivity whereas the closed state is cation-selective.
  • Tissue specificity

    Expressed in all tissues examined.
  • Sequence similarities

    Belongs to the eukaryotic mitochondrial porin family.
  • Domain

    Consists mainly of a membrane-spanning beta-barrel formed by 19 beta-strands.
  • Cellular localization

    Mitochondrion outer membrane.
