The Rap1 Myb domain adopts a canonical three-helix bundle tertiary structure, with the second and third helices forming a helix-turn-helix variant motif. The function of this domain is unclear: it may either interact with DNA via an adaptor protein or it may be only involved in protein-protein interactions [1].	Domain
