MGI Phenotype

FUNCTION: This gene encodes a member of the matrix metalloproteinase family of zinc-dependent endopeptidases capable of degrading extracellular matrix proteins. This gene is expressed specifically in the ameloblasts and odontoblasts, and the encoded protein is an inactive zymogen that requires proteolytic removal of a N-terminal propeptide to become enzymatically active. Mice lacking the encoded protein display an amelogenesis imperfecta phenotype. [provided by RefSeq, Oct 2015]
PHENOTYPE: Mice homozygous for a knockout allele exhibit a severe and profound tooth phenotype that includes altered amelogenin processing, enamel that delaminates from dentin, a hypoplastic enamel, a disorganized prism pattern, and a progressively deteriorating enamel morphology. [provided by MGI curators]
