Homology of adenoviral E3 glycoprotein with HLA-DR heavy chain.

RESUMO
The Mr 19,000 adenovirus glycoproteins coded by the E3 region that is expressed on the cell membrane and presumably binds to HLA class I antigen shows sequence homology to the alpha-chain of human HLA-DR and to the kappa-chain of human IgM. The homology extends to a conserved domain present in all of the major histocompatibility complex antigens, beta 2-microglobulins, and immunoglobulins. Predicted beta-sheet secondary structures are similar between the Mr 19,000 adenovirus protein and these immune system proteins. Evolutionary and functional implications of the homology are discussed.
