1-137 | 5.90e-94 | |||
receptor-binding domain of the S1 subunit of coronavirus spike (S) proteins; This family contains the receptor-binding domain (RBD) of the S1 subunit of coronavirus (CoV) spike (S) proteins from three highly pathogenic human coronaviruses (CoVs), including Middle East respiratory syndrome coronavirus (MERS-CoV), Severe acute respiratory syndrome (SARS) coronavirus (SARS-CoV), and SARS coronavirus 2 (SARS-CoV-2), also known as a 2019 novel coronavirus (2019-nCoV), as well as S proteins from related coronaviruses. The CoV S protein is an envelope glycoprotein that plays the most important role in viral attachment, fusion, and entry into host cells, and serves as a major target for the development of neutralizing antibodies, inhibitors of viral entry, and vaccines. It is synthesized as a precursor protein that is cleaved into an N-terminal S1 subunit (~700 amino acids) and a C-terminal S2 subunit (~600 amino acids) that mediates attachment and membrane fusion, respectively. Three S1/S2 heterodimers assemble to form a trimer spike protruding from the viral envelope. The S1 subunit contains a receptor-binding domain (RBD), while the S2 subunit contains a hydrophobic fusion peptide and two heptad repeat regions. S1 contains two structurally independent domains, the N-terminal domain (NTD) and the C-terminal domain (C-domain). Depending on the virus, either the NTD or the C-domain can serve as the receptor-binding domain (RBD). While the RBD of mouse hepatitis virus (MHV) is located at the NTD, most CoVs, including SARS-CoV-2, SARS-CoV and MERS-CoV use the C-domain to bind their receptors. MHV uses mouse carcinoembryonic antigen related cell adhesion molecule 1a (mCEACAM1a) as the receptor, and the receptors for SARS-CoV and MERS-CoV are human angiotensin-converting enzyme 2 (ACE2) and human dipeptidyl peptidase 4 (DPP4), respectively. Recent studies found that the RBD of SARS-CoV-2 S protein binds strongly to human and bat angiotensin-converting enzyme 2 (ACE2) receptors. Moreover, SARS-CoV-2 RBD exhibited significantly higher binding affinity to the ACE2 receptor than SARS-CoV RBD. Due to the key role of the S protein RBD in viral attachment, it is the major target for antibody-mediated neutralization. This model corresponds to the S1 subunit C-domain that serves as the RBD for most CoVs.

1-137 | 5.90e-94 | |||
receptor-binding domain of the S1 subunit of the Spike (S) protein from human coronavirus OC43 and related proteins; This group contains the receptor-binding domain (RBD) of the S1 subunit of the spike (S) protein from several betacoronaviruses including human coronavirus OC43 (HCoV-OC43) and bovine respiratory coronavirus (BCoV), among others. HCoV-OC43 is of zoonotic origin and is endemic in the human population, causing mild respiratory tract infections and possible severe complications or fatalities in young children, the elderly, and immunocompromised individuals. These viruses are related to the zoonotic SARS and MERS betacoronaviruses, which have high fatality rates and pandemic potential. The CoV S protein is an envelope glycoprotein that plays the most important role in viral attachment, fusion, and entry into host cells, and serves as a major target for the development of neutralizing antibodies, inhibitors of viral entry, and vaccines. It is synthesized as a precursor protein that is cleaved into an N-terminal S1 subunit (~700 amino acids) and a C-terminal S2 subunit (~600 amino acids) that mediates attachment and membrane fusion, respectively. Three S1/S2 heterodimers assemble to form a trimer spike protruding from the viral envelope. The S1 subunit contains a receptor-binding domain (RBD), while the S2 subunit contains a hydrophobic fusion peptide and two heptad repeat regions. S1 contains two structurally independent domains, the N-terminal domain (NTD) and the C-terminal domain (C-domain). Depending on the virus, either the NTD or the C-domain can serve as the receptor-binding domain (RBD). While the RBD of mouse hepatitis virus (MHV) is located at the NTD, most CoVs use the C-domain to bind their receptors. It has been reported that HCoV-OC43 uses 9-O-acetyl-sialic acid (9-O-Ac-Sia) as a receptor, which is terminally linked to oligosaccharides decorating glycoproteins and gangliosides at the host cell surface. HCoV-OC43 appears to bind 9-O-Ac-Sia at the NTD. Due to the key role of the S protein RBD in viral attachment, it is the major target for antibody-mediated neutralization. This model corresponds to the S1 subunit C-domain that serves as the RBD for most CoVs. Pssm-ID: 394832 Cd Length: 312 Bit Score: 273.81 E-value: 5.90e-94
