产品描述:                                                                                                            

Alpha-1 antitrypsin (A1AT) (H2N-Leu-Gln-His-Leu-Glu-Asn-Glu-Leu-Thr-His-Asp-Ile-Ile-Thr-Lys-OH), which is known as serum trypsin inhibitor, is a protease inhibitor belonging to the serpin superfamily.

A1AT is a single-chain glycoprotein consisting of 394 amino acids in the mature form and exhibits a number of glycoforms. The three N-linked glycosylations sites are mainly equipped with so-called diantennary N-glycans. However, one particular site shows a considerable amount of heterogeneity since tri- and even tetraantennary N-glycans can be attached to the Asparagine 107 (ExPASy amino acid nomenclature).

A1AT is a major inhibitor of human serine proteases in serum, is produced mainly by the liver, but also by extrahepatic cells, including neutrophils and certain cancer cells. [1] AAT is an acute phase protein and its concentration rises up to 3-4-fold above normal during acute inflammation. [2] Several types of cancer, including non-small cell lung adenocarcinoma, have been associated with increased serum levels of AAT. [3] Clinical studies have shown that high circulating levels of AAT directly correlate with tumor progression. Recently it was also found that plasma levels of AAT are significantly elevated in lung cancer patients and, particularly in cases with metastases. [4] Moreover, not only the native, inhibitory form of AAT, but also conformationally modified, non-inhibitory forms are suggested to play a role in modulating tumor growth and invasiveness. For example, Kataoka and co-workers have shown that the C-terminal fragment of AAT can enhance the growth and invasiveness of human pancreas adenocarcinoma cells, in vivo [5].
