Meaning and Definition

To activate something (usually a gene, cellular process, or viral component) indirectly, via the action of a separate protein or agent.

In business or technology, can be used metaphorically to describe initiating or enabling a process or function in one system through an action in a different, linked system.

Common Mistakes When Using “transactivate”

  • Using it as a synonym for general 'activation'.
  • Confusing it with 'transform' or 'transduce'.
  • Incorrect verb patterns, e.g., 'transactivate to produce' instead of 'transactivate production of'.

FAQ

Frequently Asked Questions

No. 'Activate' is general. 'Transactivate' is specific to biology/virology and means to activate indirectly, typically where one gene or protein activates another separate one.

Almost never. It is a highly specialized technical term. Using it in general conversation would likely cause confusion.

The most common noun is 'transactivation'. (e.g., 'The transactivation of the gene was observed.')

A 'transactivator' is the specific agent (usually a protein or transcription factor) that performs the action of transactivation.

To activate something (usually a gene, cellular process, or viral component) indirectly, via the action of a separate protein or agent.

Transactivate is usually formal, technical, scientific. in register.

Transactivate: in British English it is pronounced /ˌtrænzˈæk.tɪ.veɪt/, and in American English it is pronounced /ˌtrænzˈæk.tə.veɪt/. Tap the audio buttons above to hear it.

Learning

Memory Aids

Mnemonic

Think of a TRANSformer robot that can ACTIVATE another robot just by being near it. TRANS-ACTIVATE = act from across a space.

Conceptual Metaphor

A REMOTE CONTROL for genes. The transactivating protein doesn't touch the gene directly but sends a signal that turns it on.
