R-type lectin "Sevil" extracted from mussel Mytilisepta virgata strongly binds to asialo-GM1

Lectins with ricin B chains are collectively referred to as R-type lectins.
Ricin is galactose-specific, but the ricin-like structure has an extremely wide biological distribution and has various specificities such as sialic acid, mannose, xylose, etc. in addition to galactose.
The R-type lectin "Sevil" from mussel Mytilisepta virgata binds particularly strongly to the asialo-GM1 structure.
