scaffold protein


Also found in: Encyclopedia, Wikipedia.
A multivalent protein that coordinates the location of enzymes in close proximity to specific substrates. Scaffold proteins are structurally and functionally linked to macromolecule assembly, and follow ordered pathways, accomplished by switching proteins through discrete conformations as they’re incorporated into a growing molecular complex
