The helicase associated domain (HA2) has an all alpha-helical fold and consists of a N-terminal winged-helix (WH) domain and a C-terminal degenerate helical-bundle domain, referred to as the ratchet-like domain [1,2,3]. These domains collaborate with RecA domains at the N-terminal in completing an RNA binding channel to allow the helicases to keep a stable grip on the RNA [3] and assure its correct function. This entry represents the WH domain, which connects the N- (RecA domains) and C-terminal domains (ratchet-like and OB-fold) of helicases.	Domain

This family is found towards the C-terminus of the DEAD-box helicases (Pfam:PF00270). In these helicases it is apparently always found in association with Pfam:PF04408. There do seem to be a couple of instances where it occurs by itself - e.g. Swiss:Q84VZ2. The structure PDB:3i4u adopts an OB-fold. helicases (Pfam:PF00270). In these helicases it is apparently always found in association with Pfam:PF04408. This C-terminal domain of the yeast helicase contains an oligonucleotide/oligosaccharide-binding (OB)-fold which seems to be placed at the entrance of the putative nucleic acid cavity. It also constitutes the binding site for the G-patch-containing domain of Pfa1p. When found on DEAH/RHA helicases, this domain is central to the regulation of the helicase activity through its binding of both RNA and G-patch domain proteins [1].	Domain

Members of this family include the DEAD and DEAH box helicases. Helicases are involved in unwinding nucleic acids.
