摘要: Genome sequencing projects have dramatically increased the amount of sequence data available in public databases, providing an opportunity to identify new protein families. The definition families allows knowledge from studies one or a few members family be applied many other proteins family. analysis presented here defines actin-binding module, actin-depolymerizing factor homology (ADF-H) domain, which is present each member newly identified, extensive This consists three phylogenetically distinct classes: ADF/cofilins, twinfilins, and drebrin/Abp1s. Each class has been used by eukaryotic organisms for more than 1 billion years, since before divergence fungi animals. ADF-H domain can considered functional building block that arranged differently classes In addition being evolutionarily distinguishable, seem possess biochemical properties. Thus, ancient duplication allowed development diversity.
