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.内分泌腺衍生的血管内皮生长因子（EG-VEGF），也称为（PK1），是分泌蛋白的原蛋白蛋白家族的成员。

泛素化是通过三个酶促步骤实现的。在ATP依赖的过程中，泛素酶(E1)催化与泛素形成活性硫酯键，然后转移到泛素载体蛋白的活性位点半胱氨酸(E2)。泛素级联对特定底物蛋白的选择性依赖于E2结合酶(细胞中包含的相对较少)和泛素-蛋白连接酶(E3)之间的相互作用，迄今为止已经鉴定出600多种这种酶。E3s是一个大的，多样化的蛋白质组，其特征是几个确定的基序之一。这些包括HECT(与e6相关蛋白c端同源)，RING(真正有趣的新基因)或U-box(没有Zn2+结合配体的完整补充的修饰的RING基序)结构域。而HECT E3s在泛素化过程中具有直接的催化作用，RING和U-box E3s促进蛋白质泛素化。 后两种E3类型充当适配器类分子。 它们使E2和底物足够接近，从而促进底物的泛素化。虽然许多RING-type e3，如MDM2和c-Cbl，可以单独发挥作用，但其他一些是作为更大的多蛋白复合体的组成部分，如后期促进复合体。综上所述，这些多面的特性和相互作用使E3s能够利用泛素-蛋白酶体系统，在真核生物的所有细胞中提供一种强大而具体的蛋白质机制。该筛选了11种常用E2结合酶，可以筛选具有E3连接酶活性的蛋白所匹配的E2酶.RANTES是对单核细胞，记忆T细胞（CD4+/CD45RO），嗜碱性粒细胞和嗜酸性粒细胞的趋化剂。Recombinant Mouse TEM7R/PLXDC2 Protein,His Tag

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.  Recombinant Mouse LY75/CD205 Protein,His Tag
