umls-concept:C0872079 | skos:definition | CSP: interaction among or within protein domains which may alter the structure thus affecting the function of the protein or group of proteins.,NCI: Temporary, non-covalent binding between protein molecules. Protein-protein interactions occur as a result of intermolecular physical forces and spatial complementation between domains or motifs. This interaction can be either homotypic or heterotypic and effect protein structure, conformation, and function. | lld:umls |
