MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] 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. [provided by RefSeq, May 2010]
PHENOTYPE: Homozygous null mice display embryonic lethality, embryonic growth arrest, failure of embryo turning and somitogenesis, impaired placental development and impaired yolk sac vascular remodeling. [provided by MGI curators]
