    Molecular characterisation of GTP1, a Saccharomyces cerevisiae gene encoding a small GTP-binding protein (1994)
    Springer
    Current genetics 26 (1994), S. 564-566

    Notizen: Abstract DNA sequence analysis upstream of the yeast DNA repair gene SNM1 revealed gene GTP1 with an ORF of 573 bp on chromosome XIII. The putative amino-acid sequence of the encoded protein shows homology to proteins of the ARF-class of small GTP-binding proteins. Homology within GTP-binding motifs is highly conserved. Gene disruption showed that GTP1 is not an essential gene and that it has no influence on the expression of the DNA repair gene SNM1 with which it shares a 191-bp promoter region.

    Regulation of SNM1, an inducible Saccharomyces cerevisiae gene required for repair of DNA cross-links (1996)

    Notizen: Abstract  The interstrand cross-link repair gene SNM1 of Saccharomyces cerevisiae was examined for regulation in response to DNA-damaging agents. Induction of SNM1-lacZ fusions was detected in response to nitrogen mustard, cis-platinum (II) diamine dichloride, UV light, and 8-methoxypsoralen +UVA, but not after heat-shock treatment or incubation with 2-dimethylaminoethylchloride, methylmethane sulfonate or 4-nitroquinoline-N-oxide. The promoter of SNM1 contains a 15 bp motif, which shows homology to the DRE2 box of the RAD2 promoter. Similar motifs have been found in promoter regions of other damage-inducible DNA repair genes. Deletion of this motif results in loss of inducibility of SNM1. Also, a putative negative upstream regulation sequence was found to be responsible for repression of constitutive transcription of SNM1. Surprisingly, no inducibility of SNM1 was found after treatment with DNA-damaging agents in strains without an intact DUN1 gene, while regulation seems unchanged in sad1 mutants.

Surprisingly, no inducibility ofSNM1 was found after treatment with DNA-damaging agents in strains without an intactDUN1 gene, while regulation seems unchanged insad1 mutants.

    Sequence analysis of a 5·6 kb fragment of chromosome II from Saccharomyces cerevisiae reveals two new open reading frames next to CDC28 (1995)

    Notizen: The sequence of a 5653 bp DNA fragment of the right arm of chromosome II of Saccharomyces cerevisiae contains two unknown open reading frames (YBR1212 and YBR1213) next to gene CDC28. Gene disruption reveals both putative genes as non-essential. ORF YBR1212 encodes a predicted protein with 71% similarity and 65% identity (total polypeptide of 376 aa) with the 378 aa Sur1 protein of S. cerevisiae, while the putative product of ORF YBR1213, which is strongly expressed, has 28% identity with a Lactococcus lactis-secreted 45 kDa protein and 24% identity with the Saccharomyces cerevisiae AGA1 gene product. The total sequence of the fragment has been submitted to the EMBL databank (accession number X80224).
