proteingbinding
Proteingbinding, commonly rendered as protein binding, refers to the specific or nonspecific interaction between a protein and another molecule such as a small ligand, another protein, nucleic acid, carbohydrate, or membrane component. These interactions are central to cellular processes including signal transduction, enzymatic catalysis, transport, gene regulation, and structural assembly.
Binding occurs at defined sites formed by the three-dimensional arrangement of amino acid residues; complementarity in
Types of protein binding include tight, specific interactions like antibody–antigen or receptor–ligand pairs; reversible transient interactions
Experimental methods for studying protein binding include X-ray crystallography and NMR for structural detail, surface plasmon
