General rule information
[?]
| Accession | PRU01270 |
| Dates | 31-MAR-2020 (Created) 30-SEP-2022 (Last updated, Version 3) |
| Data class | Domain |
| Predictors | PROSITE; PS51922; BCOV_S1_NTD |
| Names | Betacoronavirus spike (S) glycoprotein S1 subunit N-terminal (NTD) domain; BetaCoV S1-NTD |
| Function | The receptor binding domain (RBD) of betaCoV that directly engages the receptor is commonly located in the C-terminal half of S1 [C-terminal domain (CTD)] such as in SARS-CoV, SARS-CoV-2, MERS-CoV,and BatCoV HKU4, though in rare cases such as with mouse hepatitis virus (MHV), the RBD region was identified in the S1 N-terminal domain (NTD). |
