DNA replication

  1. PAF15-PCNA exhaustion limits strand-specific DNA replication control
    Study reveals PAF15-PCNA interaction as a strand-specific constraint that couples lagging-strand synthesis capacity to global DNA replication control through dosage-sensitive mechanism.
  2. Mycobacterial gyrase inhibition depends on DNA topology
    Study reveals that antibacterial drugs inhibit different gyrase-mediated catalytic activities at varying concentrations, with DNA topology modulating drug potency beyond DNA cleavage mechanisms.
  3. Mitotic repair pathway drives chromoanasynthesis
    Study reveals mitotic microhomology-mediated break-induced replication drives chromoanasynthesis, a complex chromosomal rearrangement mechanism in cancer and congenital disorders.
  4. SFPQ helps protect repeat DNA from R-loop damage
    SFPQ directs histone H3.3 deposition to R-loops in repetitive DNA elements through DAXX recruitment, suppressing replication stress and genome instability while activating innate immune responses.
