Regulon
Regulon
Regulon (/rɛɡjʊlɒn/) is a term used in genetics and molecular biology to describe a group of genes that are regulated as a unit, typically under the control of the same regulatory gene.
Etymology
The term "Regulon" is derived from the words "Regulate" and "on", indicating the activation or regulation of a group of genes.
Definition
A regulon is a group of genes that are regulated as a unit, either being activated or repressed together. These genes are typically under the control of the same regulatory gene, which can bind to the promoter regions of the genes in the regulon and influence their transcription. The genes within a regulon can be located at different positions on the chromosome and can be involved in different cellular processes, but they are all regulated in a coordinated manner.
Related Terms
- Operon: An operon is a functioning unit of genomic DNA containing a cluster of genes under the control of a single promoter.
- Modulon: A modulon is a collection of operons, regulons, or both, that are regulated under a common global regulatory protein.
- Stimulon: A stimulon is a collection of genes and operons that are regulated in response to environmental changes or stresses.
