Summary: Enables sodium:phosphate symporter activity. Acts upstream of or within phosphate ion transport. Located in apical plasma membrane and brush border membrane. Is expressed in several structures, including extraembryonic component; genitourinary system; and small intestine.

Role of sodium-dependent Pi transporter/Npt2c on Pi homeostasis in klotho knockout mice different properties between juvenile and adult stages.
Title: Role of sodium-dependent Pi transporter/Npt2c on Pi homeostasis in klotho knockout mice different properties between juvenile and adult stages.
Acute regulation of NaPi-IIc protein by parathyroid hormone is involved in the inactivation of Na(+)-dependent Pi cotransporter activity and that phosphorylation of the transporter is involved in the rapid modification.
Title: Role of the putative PKC phosphorylation sites of the type IIc sodium-dependent phosphate transporter in parathyroid hormone regulation.
Nampt/NAD(+) system for Npt2 regulation and cellular shifts to tissues such as the liver play an important role in generating daily oscillation of plasma inorganic phosphate levels.
Title: The sodium phosphate cotransporter family and nicotinamide phosphoribosyltransferase contribute to the daily oscillation of plasma inorganic phosphate concentration.
we have generated a renal-specific and inducible knockout model of NaPi-IIc/Slc34a3. absence of NaPi-IIc does not disturb the homeostasis of Pi in mice. However, ablation of the cotransporter in weaning mice does not alter the homeostasis of Ca2+.
Title: Renal-specific and inducible depletion of NaPi-IIc/Slc34a3, the cotransporter mutated in HHRH, does not affect phosphate or calcium homeostasis in mice.
The expression of Npt2c-v1 mRNA was detected in the heart, spleen, testis, uterus, placenta, femur, cerebellum, hippocampus, diencephalon and brain stem and sperm of mouse.
Title: Identification and functional analysis of a splice variant of mouse sodium-dependent phosphate transporter Npt2c.
reduced intestinal Pi absorption in VDR (-/-) mice does not seem to be the only factor that causes hypophosphatemia; reduced Npt2a, Npt2c, or PiT-2 protein levels during development might also cause hypophosphatemia and rickets in VDR (-/-) mice.

Targeting of NaPi-IIc to the apical surface of renal epithelial cells is regulated by a unique amino acid motif in the cytoplasmic C-terminal domain.

Findings suggest that Npt2a, Npt2c, and PiT-2 are necessary for the phosphaturic activity of FGF23.

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.
