MGI Phenotype

FUNCTION: This gene encodes an extracellular matrix glycoprotein that is involved in the formation of dental enamel. Mice lacking the encoded protein fail to undergo normal ameloblast differentiation and develop enamel. Mice overproducing the product of this gene develop thinner and more porous enamel, with disrupted rod patterns and abnormal crystallites. Alternate splicing of this gene results in multiple transcript variants. [provided by RefSeq, Dec 2014]
PHENOTYPE: Homozygous null mice lack enamel and display abnormal ameloblast and tooth morphology and an increased incidence of dental epithelium derived tumors. [provided by MGI curators]
