Recombinant Mouse JAM-A Protein

Angiotensin I Converting Enzyme (ACE-2), also called ACEH (ACE homologue), is a dimeric, zinc-dependent metalloprotease of the ACE family that also includes somatic and germinal ACE. ACE-2 mRNA is found at high levels in heart, testis, and kidney and at lower levels in a wide variety of tissues. ACE-2 is the SARS-CoV and SARS-CoV2 Spike protein receptor in vivo, functions catalytically as a carboxypeptidase to cleave several substrates including angiotensins I and II, and acts as a partner for B0AT1-family amino acid transporters. Through these functions, ACE-2 has been shown to be involved in several diseases including SARS, COVID19, acute lung injury, heart disease, liver and lung fibrosis, inflammatory lung disease, and cardiopulmonary disease . Full length ACE-2 protein includes an extracellular region composed of a single N-terminal peptidase domain and C-terminal collectrin-like domain (CLD), a transmembrane domain, and a short cytoplasmic tail. The N-terminal peptidase region is required for binding to SARS-CoV and SARS-CoV2 spike proteins, while the CLD contains a region that promotes dimerization and association with amino acid transporters.SUMO蛋白酶识别完整的含有100个氨基酸的SUMO标签蛋白，并能高效地把SUMO从融合蛋白上切割下来。Recombinant Mouse JAM-A Protein,His Tag

产品描述纤维蛋白原（Fibrinogen，Fg），即凝血因子I，分子量约340kDa，由α、β、γ三对不同多肽链组成，多肽链间以二硫键相连。α链分子量63.5kDa，β链分子量56kDa，γ链分子量47kDa，纤维蛋白原约含4%碳水化合物。纤维蛋白原参与凝血的原理：在凝血酶作用下，α链与β链分别释放出A肽与B肽，生成纤维蛋白单体。在此过程中，由于释放了酸性多肽，负电性降低，单体易于聚合成纤维蛋白多聚体，但此时单体之间借氢键与疏水键相连，尚可溶于稀酸和尿素溶液中。进一步在Ca2+与活化的ⅩⅢ因子作用下，单体之间以共价键相连，则变成稳定的不溶性纤维蛋白凝块，完成凝血过程。来源于不同物种（如来源于牛、猫、狗、豚鼠、人、绵羊、小鼠和大鼠等）的纤维蛋白原具有相似的结构和性质。因此，一般来源于一种哺乳动物的纤维蛋白原可与其他来源的凝血酶交叉反应，相反地来自一种哺乳动物蛋白的凝血酶液也可注入多种动物，发生凝血反应。

SARS-CoV-2, which causes the global pandemic coronavirus disease 2019 (Covid-19), belongs to a family of viruses known as coronaviruses that also include MERS‑CoV and SARS-CoV-1. Coronaviruses are commonly comprised of four structural proteins: Spike protein (S), Envelope protein (E), Membrane protein (M) and Nucleocapsid protein (N). The SARS-CoV-2 S protein is a glycoprotein that mediates membrane fusion and viral entry. The S protein is homotrimeric, with each ~180-kDa monomer consisting of two subunits, S1 and S2 .The RBD of SARS-CoV-2 binds a metallopeptidase, angiotensin-converting enzyme 2 (ACE-2). Before binding to the ACE-2 receptor, structural analysis of the S1 trimer shows that only one of the three RBD domains is in the "up" conformation. This is an unstable and transient state that passes between trimeric subunits but is nevertheless an exposed state to be targeted for neutralizing antibody therapy. Polyclonal antibodies to the RBD of the SARS-CoV-2 protein have been shown to inhibit interaction with the ACE-2 receptor, confirming RBD as an attractive target for vaccinations or antiviral therapy.  IdeS Protease全称免疫球蛋白G降解酶是由人类致病菌酿脓链球菌产生并分泌至胞外的一种半胱氨酸水解酶。
