Invitrogen™ ATP7A Monoclonal Antibody (L60/4), PE

Description

1 μg/mL of MA5-45521 was sufficient for detection of Copper-transporting ATPase1 in 20 μg of rat brain lysate by colorimetric immunoblot analysis using Goat IgG:HRP as the secondary antibody. Detects approximately 180kDa in rat brain membrane preparations. This antibody was formerly sold as clone S60-4.

ATP7A (also known as Copper-transporting ATPase 1) functions as a transmembrane copper-translocating P-type ATPase and plays a vital role in systemic copper absorption in the gut and copper reabsorption in the kidney. Polarized epithelial cells such as Madin-Darby canine kidney cells are a physiologically relevant model for systemic copper absorption and reabsorption in vivo. Although ATP7A is not detectable in most normal tissues, it is expressed in a considerable fraction of many common tumor types. Increased expression of ATP7A renders cells resistant to cisplatin and carboplatin. Mutations in the ATP7A gene result in Menkes disease, which is fatal in early childhood.
