Data class

Domain

Predictors

PROSITE; PS51921; BCOV_S1_CTD

Names

Betacoronavirus spike (S) glycoprotein S1 subunit C-terminal (CTD) domain; BetaCoV S1-CTD

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).

Propagated annotation [?]

Comments [?]

Similarity

Belongs to the betacoronaviruses spike protein family.
