Coactivation

Definition of the noun Coactivation

What does Coactivation mean as a name of something?

noun

  1. Activation of two or more things together
  2. [genetics] A process wherein RNA transcription is increased by a coactivator protein
  3. [medicine] The activation of one muscle coordinately with another

Explanation

Coactivation is a process by which the transcription of RNA is increased. Proteins called coactivators are recruited to DNA-binding transcription factors through their activation domains and increase transcription by relaxing the chromatin structure to allow greater access to a gene or by bringing in components of the basal transcription complex needed for transcription to occur. Examples of coactivators are CBP, p300, and SWI/SNF.
