Identification of porin as a binding site for MAP2.
Porin or VDAC, the pore forming protein in the outer mitochondrial membrane, was identified as a binding site for microtubule-associated protein 2 (MAP2). By affinity chromatography using covalently bound MAP2, two proteins were selectively purified with molecular weights 63 and 70 KD. The 63 KD protein was identified to be the dimer of porin using affinity purified porin antibodies.
