corepressor

9.5
A protein that attaches to another protein to help switch off certain genes
  • noun
  • /ˌkɔːrɪˈprɛsər/

translation icon : corepresor
  • Many corepressors are involved in gene regulation.

Examples

  • Without a corepressor, the repressor cannot effectively block gene expression.

  • The corepressor binds to the regulatory protein.

  • A corepressor attaches to the repressor protein, preventing the gene from being transcribed.

  • Researchers discovered a new corepressor involved in regulating metabolic genes.

  • The role of corepressor proteins is crucial in regulating gene expression by inhibiting certain pathways.

  • Researchers discovered that a specific corepressor can help decrease the activity of genes linked to cancer.

  • Geneticists often study how corepressors like RIP140 interact with other proteins to modulate gene expression.

Surface Forms

corepressor singular
corepressors plural

Morphology

corepressor = repressor (transparent) = co + repress + or

The meaning follows directly from 'co-' (together/with) + 'repressor' (a protein that inhibits gene expression), so learners who know these parts can infer the sense.

Etymology

Corepressor combines co- meaning 'together' and repressor, which comes from the idea of press meaning 'push down'. So, a corepressor is something that works 'with' a repressor to 'push down' or turn off gene activity.
