Disease relevance of SYG1


High impact information on SYG1

  • Consistent with these genetic observations, the suppressing form of Syg1p can interact with the STE4 gene product, as determined by a two-hybrid assay [2].
  • Deletion mutants of SYG1 indicate that complete gpa1 suppression requires removal of all of these hydrophobic regions [2].
  • Interestingly, this truncated protein localizes to the same plasma membrane-enriched subcellular fraction as does full-length Syg1p [2].

Biological context of SYG1

  • One deletion mutant (SYG1 delta 340) can suppress the cell cycle arrest associated with gpa1, but the cells retain a differentiated morphology [2].
