The name of this superfamily has been modified since the most recent official CATH+ release (v4_2_0). At the point of the last release, this superfamily was: waiting to be named.
The E2 glycoproteins interact with the nucleocapsid through its cytoplasmic domain, while its ectodomain is responsible for binding a cellular receptor. This is an all beta protein belonging to the immunoglobulin superfamily, with three immunoglobulin domains labelled A, B and C in amino- to carboxy-terminal order PMID:21124458. Structural domains comprising this superfamily share the structure of the C-terminal domain, known as domain C, of the alphavirus E2 glycoprotein.
