Anti-Serpina3n Antibody, clone 13H5

产品说明

一般描述

Serine protease inhibitor A3N (UniProt: Q91WP6; also known as Serpin A3N) is encoded by the Serpina3n (also known as Spi2) gene (Gene ID: 20716) in murine species. SerpinA3N is a secreted protein of the serpin family. Serpins bind and inhibit specific serine proteases and several serine proteases are reported to be substrates for SerpinA3N in vitro. It is synthesized with a signal peptide of 20 amino acids that is cleaved to generate the mature protein. SerpinA3N is expressed at high levels in brain, heart, liver, lung, spleen, testis, and thymus. However, its expression is low in kidney, skeletal muscle, and bone marrow. Serpin A3N expression can also be induced by bacterial lipopolysaccharides. The reactive center loop (RCL) of as SerpinA3N 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 serpin reactive site and the protease. The resulting inactive serpin-protease complex is highly stable. SerpinA3N is shown to be up-regulated in the dorsal root ganglia after nerve injury and mice lacking SerpinA3N are reported to develop more neuropathic mechanical allodynia than wild-type (WT) mice. SerpinA3N is also shown to attenuate activated T cell-mediated neuronal death and reduce the severity of disease in experimental autoimmune encephalomyelitis (EAE). (Ref.: Vicuna, L et al. (2015) Nat. Med. 21(5):518-23).

特异性

Clone 13H5 specifically targets murine Serpina3n. It is predicted to react with both pro- and mature forms of Serpina3n. This clone targets a sequence within 24 amino acids from the C-terminal region.

免疫原
