CC -!- FUNCTION: The large envelope protein exists in two topological CC conformations, one which is termed 'external' or Le-HBsAg and the CC other 'internal' or Li-HBsAg. In its external conformation the CC protein attaches the virus to cell receptors and thereby CC initiating infection. This interaction determines the species CC specificity and liver tropism. It also assume fusion between CC virion membrane and cellular membrane. In its internal CC conformation the protein plays a role in virion morphogenesis and CC mediates the contact with the nucleocapsid like a matrix protein CC (By similarity). CC -!- FUNCTION: The middle envelope protein plays an important role in CC the budding of the virion. It is involved in the induction of CC budding in a nucleocapsid independent way. In this process the CC majority of envelope proteins bud to form subviral lipoprotein CC particles of 22 nm of diameter that do not contain a nucleocapsid CC (By similarity).
