  • 功能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 platelets, decreases coagulation time and has proteolytic activity against insulin and plasmin.
    Short peptide from AAT: 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).
  • 组织特异性Ubiquitous. Expressed in leukocytes and plasma.
  • 疾病相关Alpha-1-antitrypsin deficiency
  • 序列相似性Belongs to the serpin family.
  • 结构域The reactive center loop (RCL) extends out from the body of the protein and directs binding to the target protease. The protease cleaves the serpin at the reactive site within the RCL, establishing a covalent linkage between the carboxyl group of the serpin reactive site and the serine hydroxyl of the protease. The resulting inactive serpin-protease complex is highly stable.
  • 翻译后修饰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.
  • 细胞定位Secreted. Endoplasmic reticulum. The S and Z allele are not secreted effectively and accumulate intracellularly in the endoplasmic reticulum and Secreted, extracellular space, extracellular matrix.

Thank you for your message.

I can confirm that all three of the Alpha 1 anti trypsin proteins in our catalog are from human, and are full length. Therefore, theoretically, they could be detected by the antibodies in the kit and be used for y...

I can confirm that the ab77937 is also glycosylated. I hope tthis information will be helpful.

Thank you for your email. ab91136 is indeed glycosylated. I have asked our lab for confirmaiton about ab77937 also; I will forward you the information soon. I hope this will help.

Thank you for contacting us. The only difference in ab91136 and ab77937 is that ab91136 is active form of protein; which means this protein is fully guaranteed to be used in functional assays. We unfortunately do not have products related to U3...
