A Model for the Cytoplasmic Domain of the Influenza A Virus M2 Channel by Analogy to the HIV-1 Vpu Protein
A model for the cytoplasmic domain of the M2 proton channel of influenza A virus was formulated based primarily on the cytoplasmic domain of the Vpu protein of HIV-1 using sequence similarity and structure prediction techniques. The model consists of a pair of antiparallel helices followed by a strand parallel to the first helix. Structural analogies with other proteins contribute support for features of the model and suggest ways in which the M2 cytoplasmic domain can interact with other viral and cellular factors.

More about this publication?
- Protein & Peptide Letters publishes short papers in all important aspects of protein and peptide research, including structural studies, recombinant expression, function, synthesis, enzymology, immunology, molecular modeling, drug design etc. Manuscripts must have a significant element of novelty, timeliness and urgency that merit rapid publication. Reports of crystallisation, and preliminary structure determinations of biologically important proteins are acceptable. Purely theoretical papers are also acceptable provided they provide new insight into the principles of protein/peptide structure and function.
