FunctionSPG1_STRSG Binds to the constant Fc region of IgG with high affinity. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedParamagnetic lanthanide ions fixed in a protein frame induce several paramagnetic effects such as pseudo-contact shifts and residual dipolar couplings. These effects provide long-range distance and angular information for proteins and, therefore, are valuable in protein structural analysis. However, until recently this approach had been restricted to metal-binding proteins, but now it has become applicable to non-metalloproteins through the use of a lanthanide-binding tag. Here we report a lanthanide-binding peptide tag anchored via two points to the target proteins. Compared to conventional single-point attached tags, the two-point linked tag provides two to threefold stronger anisotropic effects. Though there is slight residual mobility of the lanthanide-binding tag, the present tag provides a higher anisotropic paramagnetic effect. Two-point anchoring of a lanthanide-binding peptide to a target protein enhances the paramagnetic anisotropic effect.,Saio T, Ogura K, Yokochi M, Kobashigawa Y, Inagaki F J Biomol NMR. 2009 Jul;44(3):157-66.
