NMR structure of the LCCL domain
Contents |
Overview
The LCCL domain is a recently discovered, conserved protein module named, after its presence in Limulus factor C, cochlear protein Coch-5b2 and late, gestation lung protein Lgl1. The LCCL domain plays a key role in the, autosomal dominant human deafness disorder DFNA9. Here we report the, nuclear magnetic resonance (NMR) structure of the LCCL domain from human, Coch-5b2, where dominant mutations leading to DFNA9 deafness disorder have, been identified. The fold is novel. Four of the five known DFNA9 mutations, are shown to involve at least partially solvent-exposed residues. Except, for the Trp91Arg mutant, expression of these four LCCL mutants resulted in, misfolded proteins. These results suggest that Trp91 participates in the, interaction with a binding partner. The unexpected sensitivity of the fold, with respect to mutations of solvent-accessible residues might be, attributed to interference with the folding pathway of this, disulfide-containing domain.
