Summary: Predicted to enable metalloendopeptidase activity. Acts upstream of or within bone mineralization; odontogenesis; and organophosphate metabolic process. Located in Golgi apparatus; endoplasmic reticulum; and perinuclear region of cytoplasm. Is expressed in several structures, including chondrocranium; epidermis; limb; liver; and tooth. Used to study X-linked dominant hypophosphatemic rickets and otitis media. Human ortholog(s) of this gene implicated in X-linked dominant hypophosphatemic rickets. Orthologous to human PHEX (phosphate regulating endopeptidase homolog X-linked). [provided by Alliance of Genome Resources, Apr 2022]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
