Recombinant alpha 1-antitrypsin

Identification

Name
Recombinant alpha 1-antitrypsin
Accession Number
DB05481
Description

Alpha 1-antitrypsin is a glycoprotein primarily produced by hepatocytes, and to a lesser extent, immune system cells. Recombinant alpha 1-antitrypsin (rAAT) is produced from yeast, which unlike commercially available forms of plasma-derived AAT, eliminates the risk associated with blood-borne infectious agents and allows for a increased manufacturing. rAAT belongs to a family of structurally-related proteins classified as serine protease inhibitors or SERPINS, which are known to inhibit several proteases including trypsin, cathepsin G, thrombin, tissue kallikrein, as well as neutrophil elastase. The proteinase/antiproteinase balance is believed to be important for maintaining healthy skin. The rAAT topical gel (Dermolastin™) is indicated for patients with atopic dermatitis and psoriasis. The company has indicated that other formulations for gastroenterological and urological indications will also be developed.

General Function
Serine-type endopeptidase inhibitor activity
Specific Function
Inhibitor of serine proteases. Its primary target is elastase, but it also has a moderate affinity for plasmin and thrombin. Irreversibly inhibits trypsin, chymotrypsin and plasminogen activator. T...
