Sodium-dependent phosphate transport protein 2B (NaPi2b) is a protein that in humans is encoded by the SLC34A2 gene.{{cite journal | vauthors = Feild JA, Zhang L, Brun KA, Brooks DP, Edwards RM | title = Cloning and functional characterization of a sodium-dependent phosphate transporter expressed in human lung and small intestine | journal = Biochemical and Biophysical Research Communications | volume = 258 | issue = 3 | pages = 578–582 | date = May 1999 | pmid = 10329428 | doi = 10.1006/bbrc.1999.0666 }}{{cite journal | vauthors = Xu H, Bai L, Collins JF, Ghishan FK | title = Molecular cloning, functional characterization, tissue distribution, and chromosomal localization of a human, small intestinal sodium-phosphate (Na+-Pi) transporter (SLC34A2) | journal = Genomics | volume = 62 | issue = 2 | pages = 281–284 | date = December 1999 | pmid = 10610722 | doi = 10.1006/geno.1999.6009 }}{{cite web | title = Entrez Gene: SLC34A2 solute carrier family 34 (sodium phosphate), member 2| url = https://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=10568}}

Clinical significance

Sodium-dependent phosphate transport protein 2b (NaPi2b) is a tumor-associated antigen.{{cite journal | vauthors = Yin BW, Kiyamova R, Chua R, Caballero OL, Gout I, Gryshkova V, Bhaskaran N, Souchelnytskyi S, Hellman U, Filonenko V, Jungbluth AA, Odunsi K, Lloyd KO, Old LJ, Ritter G | display-authors = 6 | title = Monoclonal antibody MX35 detects the membrane transporter NaPi2b (SLC34A2) in human carcinomas | journal = Cancer Immunity | volume = 8 | pages = 3 | date = February 2008 | pmid = 18251464 | pmc = 2935786 }}

As of April 2023, upifitamab rilsodotin, an antibody-drug conjugate (ADC) targeting NaPi2b, is in Phase 3 clinical trials for recurrent platinum-sensitive ovarian cancer.{{ClinicalTrialsGov|NCT05329545|Upifitamab Rilsodotin Maintenance in Platinum-Sensitive Recurrent Ovarian Cancer (UP-NEXT).}}
