The GlcNAc-mimicking peptide failed to bind to the amelogenin trityrosyl motif peptide when the tyrosyl residues were substituted with phenylalanine or when the third proline was replaced with threonine, as in some cases of human X-linked amelogenesis imperfecta. This study documents that molecular mimicry may play a role in stability and organization of amelogenin during amelogenesis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
