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

CGI-121 has been shown to bind to the p53-related protein kinase (PRPK) [1]. PRPK is a novel protein kinase which binds to and induces phosphorylation of the tumour suppressor protein p53. CGI-121 is part of a conserved protein complex, KEOPS. The KEOPS complex is involved in telomere uncapping and telomere elongation [2]. Interestingly this family also include archaeal homologues, formerly in the DUF509 family. A structure for these proteins has been solved by structural genomics.	Domain
