An assay has been designed for the identification of NCAM-binding proteins present in an NP-40 detergent extract of brain membranes. This method, which is capable of analyzing both heterophilic and homophilic interactions, uses species-specific antibodies against NCAM in combination with radioiodination, so that after unlabeled chicken and iodinated frog brain membrane proteins were allowed to ...
Monoclonal antibodies 13D9 and 6B9 are both specific for N-propionylated polysialic acid (NPrPSA); however, while 13D9 is protective against meningitis caused by group B meningococci and Escherichia coli capsular type K1 infection, 6B9 is not. The crystal structures of the Fabs from the two antibodies determined at 2.06 and 2.45 Å resolutions, respectively, reveal markedly different combining s...
Paired immune receptors display near-identical extracellular ligand-binding regions but have intracellular sequences with opposing signaling functions. While inhibitory receptors dampen cellular activation by recognizing self-associated molecules, the functions of activating counterparts are less clear. Here, we studied the inhibitory receptor Siglec-11 that shows uniquely human expression in b...
