Phenotypic Suppression
A genetic interaction is inferred when mutation or over expression of one gene results in suppression of any phenotype (other than lethality/growth defect) associated with mutation or over expression of another gene.

Pat1 protects centromere-specific histone H3 variant Cse4 from Psh1-mediated ubiquitination.
Evolutionarily conserved histone H3 variant Cse4 and its homologues are essential components of specialized centromere (CEN)-specific nucleosomes and serve as an epigenetic mark for CEN identity and propagation. Cse4 is a critical determinant for the structure and function of the kinetochore and is required to ensure faithful chromosome segregation. The kinetochore protein Pat1 regulates the levels and spatial distribution of ... [more]
Throughput
- Low Throughput

Additional Notes
- The increased ubiquitination of Cse4 observed in pat1 mutant strains was also diminished in the pat1/psh1 mutant strain

| PSH1 PAT1 | Affinity Capture-Western Affinity Capture-Western An interaction is inferred when a bait protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag and the associated interaction partner identified by Western blot with a specific polyclonal antibody or second epitope tag. This category is also used if an interacting protein is visualized directly by dye stain or radioactivity. Note that this differs from any co-purification experiment involving affinity capture in that the co-purification experiment involves at least one extra purification step to get rid of potential contaminating proteins. | Low | - | BioGRID | - | |
