Putative 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. Belongs to the bacteroidetes fimbrillin superfamily. FimA/Mfa1 family. A propeptide cleavage site can be predicted based on structural similarity with other family members. Still, this protein lacks the lipidation signal found in other family members, suggesting it may not be exported to the cell surface, and may not be part of the fimbriae.
