The Campylobacter major outer membrane protein Family [Function: Non-specific diffusion channels] Seed alignment | Full alignment | Pfam page | TC-DB page

Campylobacter jejuni Major Outer Membane Protein (MomP) is possibly a ß-barrel porin, which displays two folded structures: a classical oligomer and a monomer showing similar channel properties (conductance and cation selectivity). MomP is a multifunction surface protein, since it has a triple role: porin activity, it is involved in the structural organization of the outer membrane, and acts as an adhesin. The 2.1-Å resolution structure of recombinant MOMP showed that although the protein has timeric arrangement similar to OmpC, it is an 18-stranded, not 16-stranded, ß-barrel.
