Gene Information

human ... ABCA3(21)

General description

ABCA3 (ATP-binding cassette, sub-family A, member3) gene encodes a member of the ABCA subclass of ATP-binding cassette (ABC) transporters. Its expression is restricted to lungs in the type II cells expressing surfactant protein A. Its expression is up-regulated by glucocorticoids just before birth.


ATP-binding cassette sub-family A member 3 recombinant protein epitope signature tag (PrEST)

Biochem/physiol Actions

ABCA3 (ATP-binding cassette, sub-family A, member3) gene encodes a member of the ABC1 subfamily and is mainly localized to the limiting membrane of the lamellar bodies in human lung. It functions in the transmembrane transport of lipid components of pulmonary surfactant. It is involved in the metabolism of pulmonary surfactant lipids and in the biogenesis of lamellar body. Mutations in this gene are associated with fatal surfactant deficiency in neonates resulting in lethal respiratory distress and interstitial lung disease.

Features and Benefits

Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:
  • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
  • Protein array of 364 human recombinant protein fragments.


Corresponding Antigen APREST86886.

Physical form

Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide

Patients with advanced-stage bronchial cancer benefit from systemic cytostatic therapy, in particular from regimens integrating cisplatin and taxanes. However, eventual disease progression leads to a fatal outcome in most cases, originating from tumor cells resisting chemotherapy. We here show that...

ATP-binding cassette transport protein A3 (ABCA3) is expressed in non-small cell lung cancer (NSCLC). We hypothesize that high-level ABCA3 expression may have a negative prognostic impact in patients with NSCLC. In 89 patients with NSCLC and curative intended surgery, we...

We previously proposed a role for the two-pore domain potassium (K2P) channel TREK-1 in hyperoxia (HO)-induced lung injury. To determine whether redundancy among the three TREK isoforms (TREK-1, TREK-2, and TRAAK) could protect from HO-induced injury, we now examined the...

Lung surfactant accumulates in the lamellar body (LB) via not only the secretory (anterograde) pathway but also the endocytic (retrograde) pathway. Our previous studies suggested that the major surfactant components, phosphatidylcholine and surfactant protein A take independent trafficking routes in...

Alveolar type II (ATII) epithelial cells contain lamellar bodies (LBs) which synthesize and store lung surfactants. In animals, the inhibition or knockout of leucine-rich repeat kinase 2 (LRRK2) causes abnormal enlargement of LBs in ATII cells. This effect of LRRK2...
