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.
Publication
53BP1 deficiency combined with telomere dysfunction activates ATR-dependent DNA damage response.
TRF1 protects mammalian telomeres from fusion and fragility. Depletion of TRF1 leads to telomere fusions as well as accumulation of γ-H2AX foci and activation of both the ataxia telangiectasia mutated (ATM)- and the ataxia telangiectasia and Rad3 related (ATR)-mediated deoxyribonucleic acid (DNA) damage response (DDR) pathways. 53BP1, which is also present at dysfunctional telomeres, is a target of ATM that ...

- Low Throughput
Additional Notes
- figure 1. MEFs doubly deficient for TRF1 and 53BP1 show decreased chromosome-type end to end fusions but increased telomere recombination.
