Summaries for SLC34A2 Gene

Entrez Gene Summary for SLC34A2 Gene

  • 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]

GeneCards Summary for SLC34A2 Gene

SLC34A2 (Solute Carrier Family 34 Member 2) is a Protein Coding gene. Diseases associated with SLC34A2 include pulmonary alveolar microlithiasis and testicular microlithiasis. Among its related pathways are Transport to the Golgi and subsequent modification and Transport of glucose and other sugars, bile salts and organic acids, metal ions and amine compounds. GO annotations related to this gene include protein domain specific binding and phosphate ion binding. An important paralog of this gene is SLC34A1.

UniProtKB/Swiss-Prot for SLC34A2 Gene

  • 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.

  • Note=A chromosomal aberration involving SLC34A2 is found in a glioblastoma multiforme cell line U-118MG. Results in the formation of a SLC34A2-ROS1 chimeric protein that retains a constitutive kinase activity. {ECO:0000269 PubMed:12661006}.
  • Pulmonary alveolar microlithiasis (PALM) [MIM:265100]: Rare disease characterized by the deposition of calcium phosphate microliths throughout the lungs. Most patients are asymptomatic for several years or even for decades and generally, the diagnosis is incidental to clinical investigations unrelated to the disease. Cases with early-onset or rapid progression are rare. A sandstorm-appearing chest roentgenogram is a typical diagnostic finding. The onset of this potentially lethal disease varies from the neonatal period to old age and the disease follows a long-term, progressive course, resulting in a slow deterioration of lung functions. Pulmonary alveolar microlithiasis is a recessive monogenic disease with full penetrance. {ECO:0000269 PubMed:16960801}. Note=The disease is caused by mutations affecting the gene represented in this entry.
