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.

ERBB3,又称HH3(人表皮生长因子受体3),是一种I型膜糖蛋白,是酪氨酸激酶受体ERBC家族的成员。ERBP家族成员作为表皮生长因子(LU)家族的生长因子的受体。在ERBP家庭成员中,因为它含有一个缺陷的激酶域。ERBB3在角化细胞、黑色素细胞、骨骼肌细胞、成肌细胞和雪旺细胞中都有表达。单体ERbb3是一种低亲和性的受体。ERBB3与ERBB2的异聚反应形成高亲和性受体复合物。与此相反,ERBB3同向聚合或异向聚合形成了一个低亲和性的结合物。因为ERBB3含有一个有缺陷的激酶域,ERBB2的激酶域负责通过异二重瓣受体启动酪氨酸磷酸化信号。研究发现,ERBB3细胞质区内的三个离散氨基酸信号对ERBB2的转导至关重要。ERBB3的细胞质域也包含6个一致的结合主题,用于调节P85磷酸酶3激酶(PI3K)的HS2领域,以及一个丰富的一致的结合主题。ERBB3的细胞质域也包含6个一致的结合主题,用于调节P85磷酸酶3激酶(PI3K)的HS2领域,以及一个丰富的一致的结合主题。ERBB3的细胞质域也包含6个一致的结合主题,用于调节P85磷酸酶3激酶(PI3K)的HS2领域,以及一个丰富的一致的结合主题。表达区间及表达系统重组的人HR3/ERBB3蛋白表达自于C-端的HK293细胞和AVI标记。里面有血清20-Thr643。分子量大约71.6Recombinant Mouse LIX/CXCL5
