OnCo

A checkpoint kinase that gives cells time to fix DNA before dividing. Removing it forces damaged cancer cells into a fatal division. This dossier gathers the 0 products (0 approved), 0 trials, 5 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.

Pathways where it is a node

Pathway-to-drug matrix →
  • Circadian control
    Node: Cell-cycle gating (WEE1, MYC) · 1 druggable nodes

    Cells run on a 24-hour clock that gates cell division, DNA repair, and drug metabolism. Cancers often break their clocks, and the time of day a drug or immunotherapy is given can change how well it works.

    Which nodes have drugs →
  • DNA replication stress
    Node: WEE1 / PKMYT1 restrain CDK1 · 4 druggable nodes

    Cancers copy their DNA too fast and with broken checkpoints, so replication forks stall and collapse. They survive only by leaning on emergency repair kinases such as ATR, CHK1, and WEE1, which is why blocking those kinases can be selectively lethal.

    Which nodes have drugs →
  • p53 / RB / cell-cycle checkpoint
    Node: WEE1 (G2/M) · 4 druggable nodes

    The p53 and RB checkpoints are the cell's brakes. p53 senses damage and stops the cell from copying itself; RB holds the cell at the G1 gate until CDK4/6 unlocks it. Cancers cut these brakes.

  • Synthetic lethality: paired dependencies
    Node: → WEE1, PKMYT1, ATR · 7 druggable nodes

    Two genes are synthetically lethal when losing either alone is fine but losing both kills the cell. Cancers that have already lost one (a tumour suppressor you cannot put back) become uniquely dependent on the other, which you can drug. BRCA and PARP was the first proof; a dozen more pairs are now in trials.

    Which nodes have drugs →
  • The cell-cycle engine (cyclins & CDKs)
    Node: WEE1 / PKMYT1 · 4 druggable nodes

    Cell division runs on a clock made of cyclins and their kinases (CDKs), each pair firing in order: D-CDK4/6 to leave rest, E-CDK2 to start copying DNA, A-CDK2 to finish, B-CDK1 to divide. Cancers speed the clock; CDK inhibitors slow it.
