Chemically-induced dimerization

Definition

Chemically-induced dimerization refers to the process where two identical or similar molecules, known as monomers, are chemically linked together to form a dimer, often in response to a specific chemical trigger or signal. This technique is commonly used in synthetic biology to control the activity of proteins or other biomolecules, providing a mechanism to regulate gene expression and cellular functions through the design and construction of synthetic genetic circuits.
