The partial sequence analysis showed that this gene,called SUVi (S-phase UV inducible, DDBJ/EMBL/GenBank accession no. Y11338), contains a domain conserved among different helicases. The protein showed a high homology with the domain I of CHLR1 and the yeast CHL1, the latter being a helicase involved in normal cell cycle progression in G2/M
phase and in chromosome stability [6].
