Adaptor proteins are molecules that are needed in a signalling pathway to organise, activate, and coordinate the pathway or molecules associated with pathway. There are two given types of adaptor molecules. TRAPS which are adaptor proteins in the transmembrane and CAPS which are cytoplasmic adaptor proteins.
