In molecular biology the haemagglutination activity domain is a conserved protein domain found near the N terminus of a number of large repetitive bacterial proteins including many proteins of over 2500 amino acids. A number of the members of this family have been designated adhesins filamentous haemagglutinins haem/haemopexin-binding protein etc. Members generally have a signal sequence then an intervening region then the region described in this entry.
