ASC-1 homology domain, subfamily similar to Enterococcus faecalis Ef3133. The ASCH domain, a small beta-barrel domain found in all three kingdoms of life, resembles the RNA-binding PUA domain and may also interact with RNA. ASCH has been proposed to function as an RNA-binding domain during coactivation, RNA-processing and the regulation of prokaryotic translation.
