NMR STUDY OF A PAIR OF LDL RECEPTOR CA2+ BINDING EPIDERMAL GROWTH FACTOR-LIKE DOMAINS, 20 STRUCTURES
Contents |
Overview
BACKGROUND: From the observed structure and sequence of a pair of calcium, binding (cb) epidermal growth factor-like (EGF) domains from human, fibrillin-1, we proposed that many tandem cbEGF domains adopt a conserved, relative conformation. The low-density lipoprotein receptor (LDLR), which, is functionally unrelated to fibrillin-1, contains a single pair of EGF, domains that was chosen for study in the validation of this hypothesis., The LDLR is the protein that is defective in familial, hypercholesterolaemia, a common genetic disorder that predisposes, individuals to cardiovascular complications and premature death. RESULTS:, Here, we present the solution structure of the first two EGF domains from, the LDL receptor, determined using conventional NMR restraints and, residual dipolar couplings. The cbEGF domains have an elongated, rod-like, arrangement, as predicted. The new structure allows a detailed assessment, of the consequences of mutations associated with familial, hypercholesterolaemia to be made. CONCLUSIONS: The validation of the, conserved arrangement of EGF domains in functionally distinct proteins has, important implications for structural genomics, since multiple tandem, cbEGF pairs have been identified in many essential proteins that are, implicated in human disease. Our results provide the means to use homology, modeling to probe structure-function relationships in this diverse family, of proteins and may hold the potential for the design of novel diagnostics, and therapies in the future.
