The attachment proteins in adenoviruses and reoviruses display structural similarity, indicating similar cell-surface receptor binding strategies, even though these viruses differ from one another in design, capsid composition and genome composition [PubMed10553913, PubMed11782420]. The dsDNA adenoviruses are responsible for diseases such as pneumonia, cystitis, conjunctivitis and diarrhoea, all of which can be fatal to patients who are immunocompromised, while the dsRNA reoviruses are responsible for mild respiratory or gastrointestinal infections.

The attachment proteins play a pivotal role in disease patterns through their selective recognition of cell-surface receptors. The fibre protein and the sigma 1 protein act as attachment proteins in adenoviruses and reoviruses, respectively. The attachment proteins are homo-trimeric, and contain a long, thin central shaft, or tail domain, and a C-terminal head domain that plays an important role in cell attachment. The structure of the shaft or tail domain reveals a triple beta-spiral that is formed by interlocking beta-hairpin repeat units.

Browse genome assignments for this superfamily. The SUPERFAMILY hidden Markov model library has been used to carry out SCOP domain assignments to all genomes at the superfamily level.

Alignments of sequences to 2 models in this superfamily are available by clicking on the 'Alignments' icon above. PDB sequences less than 40% identical are shown by default, but any other sequence(s) may be aligned. Select PDB sequences, genome sequences, or paste in or upload your own sequences.

Browse and view proteins in genomes which have different domain combinations including a Fibre shaft of virus attachment proteins domain.

Examine the distribution of domain superfamilies, or families, across the major taxonomic kingdoms or genomes within a kingdom. This gives an immediate impression of how superfamilies, or families, are restricted to certain kingdoms of life.

Explore domain occurrence network where nodes represent genomes and edges are domain architectures (shared between genomes) containing the superfamily of interest.

There are 2 hidden Markov models representing the Fibre shaft of virus attachment proteins superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
