Specificity / Sensitivity

NaPi2b/SLC34A2 (D6W2G) Rabbit mAb

recognizes endogenous levels of total NaPi2b/SLC34A2 protein.

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues near the amino terminus of human NaPi2b/SLC34A2 protein.

The sodium-dependent phosphate transport protein 2B (NaPi-2b, SLC34A2) is a sodium dependent inorganic phosphate (Pi) transporter that regulates phosphate homeostasis in various organs, including the small intestine, lung, liver, and testis (1). In the small intestine, NaPi-2b localizes to the intestinal brush border membrane to mediate Pi reabsorption (2). In the lung, NaPi-2b is expressed in the apical membrane of type II alveolar cells and is involved in the synthesis of surfactant (3). Mutations in the corresponding SLC34A2 gene causes pulmonary alveolar microlithiasis, a rare autosomal recessive disorder characterized by the deposition of calcium phosphate microliths throughout the lungs (4). Research studies show aberrant expression of NaPi-2b in various type of cancer, including ovarian, breast, and lung cancer (5). Chromosomal rearrangements involving SLC34A2-ROS1 are seen in gastric carcinoma and non-small cell lung cancer and result in the formation of a SLC34A2-ROS1 chimeric protein that retains a constitutive kinase activity (6,7).
