General rule information
[?]
Accession | PRU01272 |
Dates | 14-APR-2020 (Created) 30-SEP-2022 (Last updated, Version 3) |
Data class | Domain |
Predictors | PROSITE; PS51924; COV_S2_HR2 |
Name | Coronavirus spike (S) glycoprotein S2 subunit heptad repeat 2 (HR2) region |
Function | The S2 subunit contains two 4-3 heptad repeats (HRs) of hydrophobic residues, HR1 and HR2, typical of coiled coils, separated by an ~170-aa-long intervening domain. The S2 subunit is expected to present rearrangement of its HRs to form a stable 6-helix bundle fusion core. |
