Protein

Sodium-dependent phosphate transport protein 2B

Gene

Slc34a2

Organism
Mus musculus (Mouse)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at transcript leveli

Functioni

May be involved in actively transporting phosphate into cells via Na+ cotransport. It may be the main phosphate transport protein in the intestinal brush border membrane. May have a role in the synthesis of surfactant in lungs' alveoli.
