DDRM3/HZE11 forms the E3 ubiquitin ligase CRL4DDRM3 with DDB1 and mediates CDT1 polyubiquitination and degradation to facilitate homologous recombination in Arabidopsis thaliana.
- Why it matters: Plant homologous recombination is accurate but its regulatory control is not well defined, especially how replication licensing factors are managed after DNA double-strand breaks.
- What they did: The study used Arabidopsis thaliana ddrm3 mutants and biochemical interaction assays to show CRL4DDRM3 targets CDT1, with genetic tests using CDT1 silencing and CDT1 overexpression.
- The result: ddrm3 mutants show reduced HR efficiency and hypersensitivity to multiple DSB-inducing agents, while CDT1 silencing partially rescues this phenotype and CDT1 overexpression reduces HR efficiency.
