产品介绍 background:
Alpha-1-antitrypsin is a protease inhibitor, deficiency of which is associated with emphysema and liver disease. The protein is encoded by a gene (PI) located on the distal long arm of chromosome 14.

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. The aberrant form inhibits insulin-induced NO synthesis in plaets, decreases coagulation time and has proteolytic activity against insulin and plasmin. 
Short peptide from AAT (SPAAT) is a reversible chymotrypsin inhibitor. It also inhibits elastase, but not trypsin. Its major physiological function is the protection of the lower respiratory tract against proteolytic destruction by human leukocyte elastase (HLE).

Subcellular Location:
Secreted.
Short peptide from AAT: Secreted, extracellular space, extracellular matrix. 

Tissue Specificity:
Plasma.

Post-translational modifications:
N-glycosylated. Differential glycosylation produces a number of isoforms. N-linked glycan at Asn-107 is alternatively di-antennary, tri-antennary or tetra-antennary. The glycan at Asn-70 is di-antennary with trace amounts of tri-antennary. Glycan at Asn-271 is exclusively di-antennary. Structure of glycans at Asn-70 and Asn-271 is Hex5HexNAc4. The structure of the antennae is Neu5Ac(alpha1-6)Gal(beta1-4)GlcNAc attached to the core structure Man(alpha1-6)[Man(alpha1-3)]Man(beta1-4)GlcNAc(beta1-4)GlcNAc. Some antennae are fucosylated, which forms a Lewis-X determinant. 
Proteolytic processing may yield the truncated form that ranges from Asp-30 to Lys-418. 

DISEASE:
Defects in SERPINA1 are the cause of alpha-1-antitrypsin deficiency (A1ATD) [MIM:613490]. A disorder whose most common manifestation is emphysema, which becomes evident by the third to fourth decade. A less common manifestation of the deficiency is liver disease, which occurs in children and adults, and may result in cirrhosis and liver failure. Environmental factors, particularly cigarette smoking, greatly increase the risk of emphysema at an earlier age.
缺乏是zui常见的遗传代谢病，能引起肺和肝的损伤。α1抗*为呼吸系统的非特异性可溶因子，与呼吸道抵抗力关系密切，它可抑制多种酶的活性，包括细菌的酶，以及中性白细胞溶酶体分泌的蛋白酶、弹性蛋白酶、胶原酶、纤维蛋白溶酶和*。α1抗*的缺乏与慢性阻塞性肺病的形成关系密切，因为它的缺乏，不能及时控制感染和炎症产生的多种蛋白酶，而造成肺组织破坏。

α1-抗*由肝细胞产生,是一种分子量为45-56kDa的糖蛋白,它能抑制蛋白酶、弹性蛋白酶、胶原酶等多种水解酶的活性。
AAT也是一种糖蛋白，主要用于遗传性AAT缺乏症和良性恶性肝肿瘤、内胚窦瘤、组织细胞性淋巴瘤以及胰腺癌、胃癌、结肠癌等各种肿瘤的研究。此抗体与大、小鼠、狗和猪有交叉反应。
