MGI Phenotype |
FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a secreted calcium-binding phosphoprotein that belongs to the small integrin-binding ligand, N-linked glycoprotein (SIBLING) family of proteins. Members of this family are components of the extracellular matrix of bone and dentin and regulate bone mineralization. Deficiency of a similar protein in mouse results in increased bone mass. Mice lacking this gene are resistant to aging-related trabecular bone loss. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2014] PHENOTYPE: Mice homozygous for disruptions in this gene have increased amounts of trabecular bone in their skeleton and undergo less age related bone loss. Otherwise, they display a normal phenotype. [provided by MGI curators]

Nature of Mutation |
DNA sequencing using the SOLiD technique identified an A to G transition at position 447 of the Mepe transcript in exon 3 of 3 total exons. The mutated nucleotide causes an isoleucine to methionine substitution at amino acid 127 of the encoded protein. The mutation has been confirmed by DNA sequencing using the Sanger method (Figure 1).
|
Protein Function and Prediction |
The Mepe gene encodes a 441 amino acid secreted matrix protein that negatively regulates bone mineralization (Uniprot Q924I1). Mice homozygous for disruptions in this gene have increased amounts of trabecular bone in their skeleton and undergo less age related bone loss. Otherwise, they display a normal phenotype.
The I127M change is predicted to be benign by the PolyPhen program.
