Negative Genetic

Mutations/deletions in separate genes, each of which alone causes a minimal phenotype, but when combined in the same cell results in a more severe fitness defect or lethality under a given condition. This term is reserved for high or low throughput studies with scores.


Reconstitution and protein composition analysis of endocytic actin patches.

Michelot A, Costanzo M, Sarkeshik A, Boone C, Yates JR, Drubin DG

Clathrin-actin-mediated endocytosis in yeast involves the progressive assembly of at least 60 different proteins at cortical sites. More than half of these proteins are involved in the assembly of a branched network of actin filaments to provide the forces required for plasma membrane invagination.To gain insights into the regulation of endocytic actin patch dynamics, we developed an in vitro actin ...

Ontology Terms

  • phenotype: colony size (APO:0000063)

Additional Notes

  • A Synthetic Genetic Array (SGA) analysis was carried out to quantitatively score genetic interactions based on fitness defects that were estimated from the colony size of double versus single mutants. Genetic interactions were considered significant if they had an SGA score of epsilon > 0.08 for positive interactions and epsilon < -0.08 for negative interactions, and a p-value < 0.05.
