Summaries for ABCA3 Gene

Entrez Gene Summary for ABCA3 Gene

  • The membrane-associated protein encoded by this gene is a member of the superfamily of ATP-binding cassette (ABC) transporters. ABC proteins transport various molecules across extra- and intracellular membranes. ABC genes are divided into seven distinct subfamilies (ABC1, MDR/TAP, MRP, ALD, OABP, GCN20, White). This protein is a member of the ABC1 subfamily. Members of the ABC1 subfamily comprise the only major ABC subfamily found exclusively in multicellular eukaryotes. The full transporter encoded by this gene may be involved in development of resistance to xenobiotics and engulfment during programmed cell death. [provided by RefSeq, Jul 2008]

GeneCards Summary for ABCA3 Gene

ABCA3 (ATP-Binding Cassette, Sub-Family A (ABC1), Member 3) is a Protein Coding gene. Diseases associated with ABCA3 include surfactant metabolism dysfunction, pulmonary, 3 and abca3-related pulmonary surfactant metabolism dysfunction. Among its related pathways are Transport of glucose and other sugars, bile salts and organic acids, metal ions and amine compounds and ABC-family proteins mediated transport. GO annotations related to this gene include transporter activity and ATPase activity, coupled to transmembrane movement of substances. An important paralog of this gene is ABCA4.

  • Pulmonary surfactant metabolism dysfunction 3 (SMDP3) [MIM:610921]: A rare lung disorder due to impaired surfactant homeostasis. It is characterized by alveolar filling with floccular material that stains positive using the periodic acid-Schiff method and is derived from surfactant phospholipids and protein components. Excessive lipoproteins accumulation in the alveoli results in severe respiratory distress. {ECO:0000269 PubMed:15044640}. Note=The disease is caused by mutations affecting the gene represented in this entry.
