Abstract:
Cellular protein-metabolite interactions (PMI), for decades relatively overlooked, are seeing a golden age in recent years. To facilitate simultaneous characterization of PMI and protein-protein interactions (PPI) of a given protein ("bait"), we developed a protocol that utilizes antibody-assisted affinity purification (AP) followed by liquid chromatography-mass spectrometry (LC-MS). Aside from its speed, simplicity, and adaptability to a variety of biological systems, its main strength lies in the parallel identification, in a near-physiological environment, of a given protein's protein and small-molecule partners.
