While sequencing a region of chromosome IV adjacent to the checkpoint gene MEC3, we identified a gene we call GUF1 (GTPase of Unknown Function), which predicts a 586 amino acid GTPase of the elongation factor‐type class. The predicted Guf1p protein bears striking sequence similarity to both LepA from Escherichia coli (43% identical) and LK1236·1 from Caenorhabditis elegans (42% identical). Analysis of both a guf1δ deletion and a putative constitutive‐activating mutant (GUF1HG) revealed that GUF1 is not essential nor did mutant cells reveal any marked phenotype. The GenBank Accession Number for the GUF1 sequence is U22360.
