CAP2

F-actin-capping protein subunit beta, L000000215, YIL034C
Beta subunit of the capping protein heterodimer (Cap1p and Cap2p); capping protein (CP) binds to the barbed ends of actin filaments preventing further polymerization; localized predominantly to cortical actin patches; protein increases in abundance and relocalizes from bud neck to plasma membrane upon DNA replication stress

AIP1

L000000069, YMR092C
Actin cortical patch component; interacts with the actin depolymerizing factor cofilin; inhibits elongation of aged ADP-actin filaments decorated with cofilin to maintain a high level of assembly-competent actin species; required to restrict cofilin localization to cortical patches; putative regulator of cytokinesis; contains WD repeats; protein increases in abundance and relocalizes from cytoplasm to plasma membrane upon DNA replication stress

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.

Actin filament elongation in Arp2/3-derived networks is controlled by three distinct mechanisms.

Michelot A, Grassart A, Okreglak V, Costanzo M, Boone C, Drubin DG

Spatial and temporal control of actin filament barbed end elongation is crucial for force generation by actin networks. In this study, genetics, cell biology, and biochemistry were used to reveal three complementary mechanisms that regulate actin filament barbed end elongation in Arp2/3-derived networks. Aip1 inhibits elongation of aged ADP-actin filaments decorated with cofilin and, together with capping protein (CP), maintains ... [more]

Throughput

  • Low Throughput

Ontology Terms

  • phenotype: synthetic growth defect (APO:0000182)

Additional Notes

  • Negative genetic interactions are defined by the intermediate cutoff in Costanzo et al 2010. Figure shows actin patch proteins that genetically interact with both cap1D and cap2D. Protein hits are grouped as actin alleles, aip1 and cof1-5
