Background: The protein encoded by this gene is a pH -sensitive sodium-dependent phosphate transporter. Phosphate uptake is increased at lower pH . Defects in this gene are a cause of pulmonary alveolar microlithiasis. Three transcript variants encoding two different isoforms have been found for this gene.
