Members of this family are found in Rio2, and are structurally homologous to the winged helix (wHTH) domain. They adopt a structure consisting of four alpha helices followed by two beta strands and a fifth alpha helix. The domain confers DNA binding properties to the protein, as per other winged helix domains [1].	Domain

This is the atypical serine kinase domain found in RIO family of proteins and related sequences, which is conserved in archaea, bacteria and eukaryotes [5,6]. Activity of Rio1 is vital in Saccharomyces cerevisiae for the processing of ribosomal RNA, as well as for proper cell cycle progression and chromosome maintenance. The structure of RIO1 has been determined [4]. This domain is also found at the C-terminal of EKC/KEOPS complex subunit BUD32 from Fungi and Kae1/Bud32 from archaea [6].	Domain
