Abstract

The Gag polyprotein from retroviruses is processed by viral protease to produce the major structural proteins, including the capsid protein. The newly formed capsid protein rearranges to form the capsid core particle that surrounds the viral genome of the mature virus. The capsid is composed of two domains, the N-terminal domain (NTD), which contributes to viral core formation, and the C-terminal domain (CTD), which is required for capsid dimerisation, Gag oligomerization and viral formation. The NTD is composed of a five-helix bundle [PubMed9931251, PubMed10669613].

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 6 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 Retrovirus capsid protein, N-terminal core domain 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 6 hidden Markov models representing the Retrovirus capsid protein, N-terminal core domain superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
