In biochemistry and molecular biology, a binding site is a region on a macromolecule such as a protein that binds to another molecule with specificity.

TRPM2's activation by Ca²⁺ and ADP ribose (ADPR), an NAD⁺-metabolite produced under oxidative stress and neurodegenerative conditions, suggests a …. ligand binding sites. The microscopic association constant reflects the equilibrium that would be measured if only one ligand can bind (as is the case for an isolated Fab fragment). The relationship between the microscopic binding constant Kmicro, and the two macroscopic binding constants can be obtained by considering the reaction rates. The identification of specific ligand-binding site (LBS) on proteins is often the first important step toward understanding the function of protein molecules, or for rational design of new therapeutic compounds to modulate the protein functions (Greer et al., 1994; Hubbard, 2006). Due to the technical difficulties and high cost associated with experimental determination, however, the structural details for protein–ligand interactions are unknown for most proteins.

The determination of the binding cleft, and preferably the binding mode, of lead compounds has become a fundamental step of structure-based drug design. Protein binding site locations for COACH is a meta-server approach to protein-ligand binding site prediction. Starting from given structure of target proteins, COACH will generate complementray ligand binding site predictions using two comparative methods, TM-SITE and S-SITE, which recognize ligand-binding templates from the BioLiP protein function database by binding-specific substructure and sequence profile comparisons. 2002-04-15 · Our results suggest that the ligand binding site in ICOS maps to a region overlapping yet distinct from the CD80/CD86 binding sites in CD28 and cytotoxic T lymphocyte antigen (CTLA)-4. Thus, the analysis suggests that differences in ligand binding specificity between these related costimulatory molecules have evolved by utilization of overlapping regions with different patterns of conserved Therefore, interactions between ligands on adjacent monomers may be possible if their binding sites on collagen align vertically, or nearly so, within the D-period and if their structure allows them simultaneously to bind one triple helix and to reach another ligand or ligand-binding site on at least one neighboring monomer. 2009-12-04 · Ligand binding sites as defined by the non-redundant version of the LigASite dataset (v7.0) were used to evaluate method predictions. This set consists of 337 proteins with apo (unbound) structures, each having less than 25% sequence identity with any other protein in the set.

SiteMap highlights regions within the binding site suitable for occupancy by hydrophobic groups or by ligand hydrogen-bond donors, acceptors, or metal-binding functionality. Distinguishing the different binding site sub-regions allows for ready assessment of a ligand's complementarity. Tools for exploiting targets of opportunity:

If either the natural ligand or an agonist binds to the receptor site, the basal activity is increased. If however, an inverse agonists binds, the activity is decreased. An example of an inverse agonist (which we will discuss later) is the binding of the drug Ro15-4513 to the GABA receptor, which also binds benzodiazepines such as valium.

In biochemistry and pharmacology, a ligand is a substance that forms a complex with a biomolecule to serve a biological purpose. The etymology stems from ligare, which means 'to bind'. In protein-ligand binding, the ligand is usually a molecule which produces a signal by binding to a site on a target protein.
