Definition
corepressors
noun
- Proteins that bind to repressor proteins and enable them to block gene transcription by preventing RNA polymerase from accessing DNA.
Usage: biology; molecular biology; plural form of corepressor
Examples
- Corepressors work together with repressor proteins to silence specific genes.
- The lac operon uses corepressors to regulate the production of lactose-digesting enzymes.
- In eukaryotes, corepressors are often part of larger protein complexes that modify chromatin structure.
- Researchers study corepressors to understand how cells control gene expression.
- Mutations affecting corepressors can lead to improper gene regulation and disease.
