Structural highlights 1ucb is a 2 chain structure with sequence from Homo sapiens. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance. Method: X-ray diffraction, Resolution 2.5Å Ligands: Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Disease IGKC_HUMAN Defects in IGKC are the cause of immunoglobulin kappa light chain deficiency (IGKCD) [MIM:614102. IGKCD is a disease characterized by the complete absence of immunoglobulin kappa chains. Function IGKC_HUMAN Evolutionary Conservation Check, as determined by ConSurfDB.

Publication Abstract from PubMed The X-ray structure of the uncomplexed human chimeric Fab' of the anti-tumor antibody BR96 has been determined at 2.6 A resolution. The structure has been compared with Lewis Y antigen-complexed structures of BR96 which were determined previously. The comparison reveals segmental motions and/or conformational rearrangements of three CDR loops (L1, L3, and H2), whereas CDR H3 does not undergo changes upon complexation despite its significant main-chain contacts to the carbohydrate antigen. In light of the uncomplexed chimeric Fab' structure reported here, the previously observed high mobility of the CL:CH1 domains of the complexed chimeric BR96 Fab is rationalized as a "swinging" motion approximately about the axis of the elbow bend.
