High impact information on GCV1

  • This protein protected a 17-base pair CATCN7CTTCTT region of GCV2 that is conserved between GCV1 and GCV2 [1].
  • GCV1 and GCV3 have an homologous region in their promoters [1].
  • The GCV1 region conferred a glycine response on an heterologous promoter acting as a repressor or activator depending on promoter context [1].
  • A protein was identified that bound to the glycine regulatory regions of GCV1 and GCV2 only if the CTTCTT motif was intact [1].
  • Growth of shm1 shm2 mutants was stimulated by glycine, whereas glycine could not supplement the growth of the isogenic gcv1 strain [2].

Biological context of GCV1

  • A DNA fragment encoding the GCV1 gene was cloned by PCR amplification using degenerate oligodeoxyribonucleotides, and the cloned fragment was used as a probe to isolate the complete gene from a yeast genomic library [2].
  • The URA3 gene was inserted into the coding sequence of GCV1 and the resulting construct was used to disrupt the chromosomal GCV1 gene in a diploid strain of yeast. gcv1::URA3 haploid derivatives grew normally or only slightly more slowly than the isogenic wild-type haploids [2].
