Summary: Enables sodium:phosphate symporter activity. Involved in several processes, including inorganic diphosphate transport; phosphate ion homeostasis; and response to sodium phosphate. Acts upstream of or within bone remodeling. Located in apical plasma membrane; basolateral plasma membrane; and vesicle. Is expressed in genitourinary system; ileum; skeleton; and tooth. Used to study hereditary hypophosphatemic rickets with hypercalciuria. Human ortholog(s) of this gene implicated in several diseases, including Fanconi syndrome (multiple); chronic kidney disease; hereditary hypophosphatemic rickets with hypercalciuria; hypophosphatemic nephrolithiasis/osteoporosis 1; and nephrolithiasis. Orthologous to human SLC34A1 (solute carrier family 34 member 1). [provided by Alliance of Genome Resources, Nov 2024]

Results show that urine pyrophosphate (PPI) levels are increased in Npt2a-/- mice when compared to WT, possibly to protect from renal mineralization in the setting of hyperphosphaturia. However, the presence of two hypomorphic Enpp1asj/asj alleles decreases urine PPi and worsens renal calcium phosphate deposit formation in Npt2a-/- mice.

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.
