Probably a component of the fimbrium tip. Fimbriae are filamentous appendages on the cell surface that mediate cell adhesion and biofilm formation. May be part of the fimbrial tip. Probably synthesized as a palmitoylated precursor. Efficient export to the outer membrane and integration into fimbriae requires lipidation and subsequent proteolytic removal of the lipidated propeptide. Probably part of the fimbrium tip. Belongs to the bacteroidetes fimbrillin superfamily. Mfa-like family.
