产品介绍  :  HBV surface proteins [Hepatitis B virus]. Major surface antigen from hepadnavirus; pfam00695.

Function:

The large envelope protein exists in two topological conformations, one which is termed 'external' or Le-HBsAg and the other 'internal' or Li-HBsAg. In its external conformation the protein attaches the virus to cell receptors and thereby initiating infection. This interaction determines the species specificity and liver tropism. This attachment induces virion internalization predominantly through caveolin-mediated endocytosis. The large envelope protein also assumes fusion between virion membrane and endosomal membrane (Probable). In its internal conformation the protein plays a role in virion morphogenesis and mediates the contact with the nucleocapsid like a matrix protein.

The middle envelope protein plays an important role in the budding of the virion. It is involved in the induction of budding in a nucleocapsid independent way. In this process the majority of envelope proteins bud to form subviral lipoprotein particles of 22 nm of diameter that do not contain a nucleocapsid.

Subunit:

Li-HBsAg interacts with capsid protein and with HDV Large delta antigen. Isoform M associates with host chaperone CANX through its pre-S2 N glycan. This association may be essential for M proper secretion.

Subcellular Location:

Virion membrane.

Post-translational modifications:

Isoform M is N-terminaly acetylated at a ratio of 90%, and N-glycosylated at the pre-S2 region.

Myristoylated.

Similarity:

Belongs to the orthohepadnavirus major surface antigen family.
