Research progress on a new multifunction protein family-DABB class proteins.

Abstract

DABB class protein contains one to two (Dimeric α+β barrel domains, DABB). DABB domain was first discovered at the Cterminus of fructose 1,6-bisphosphate aldolase from Hydrogenophilus thermoluteolus and in heat shock protein (Hsp90) and hydroxyproline glycoprotein (HRGP) from salt stressed Populus euphratica. As reported, DABB class proteins at present were mainly from plants, bacteria and fungi, and no DABB class proteins have yet been reported in animals. In plants, DABB class proteins are related to the resistance to invasions of various pathogenic fungi as well as to abiotic stresses, while in bacteria DABB class proteins mainly involve in metabolic processes that relate to oxidation-reduction reactions. Nowadays, the specific function of DABB domain was still unclear, and there was no review literature about DABB class proteins. This paper summarized the research advanced on DABB class proteins in plants and bacteria in terms of origin of species that contain DABB class proteins, the features of DABB structure domain and its conserved amino acids, as well as phyletic evolution of DABB class proteins. Finally, the functional study in future and the application foreground about DABB class proteins might be prospected.
