MONOCYTE CHEMOATTRACTANT PROTEIN-3, NMR, MINIMIZED AVERAGE STRUCTURE
OverviewOverview
1H-NMR spectroscopy and analytical ultracentrifugation studies reveal that, monocyte chemoattractant protein-3 (MCP-3) is a monomer. NMR solution, structure shows that MCP-3 adopts an alphabeta fold similar to what is, observed in structures of other known chemokines. However, MCP-3 is unique, in that it does not show a propensity to form dimers. The closely related, chemokines MCP-1 and MCP-2 show a monomer-dimer equilibrium in, sedimentation equilibrium studies (approximately 0.2-2 mg/ml). As these, proteins are present at nanomolar concentrations in vivo, the results, suggest that they are monomeric at functional concentrations and that the, monomer is the functionally significant form of MCP-1, MCP-2 and MCP-3.
