This entry represents structurally homologous matrix proteins from different retroviruses, their structure consisting of four-five alpha helices in a right-handed superhelix. Retroviral matrix proteins bearing this structure have been isolated from Human immunodeficiency virus (HIV), Simian immunodeficiency virus (SIV-cpz), Human T-cell leukemia virus type 1 (HTLV-1), Human T-cell leukemia virus type 2 (HTLV-II), Simian Mason-Pfizer virus (MPMV), Rous sarcoma virus (RSV), Equine infectious anemia virus (EIAV), and Mason-Pfizer monkey virus (MMLV). This entry also identifies matrix proteins from several eukaryotic endogenous retroviruses, which arise when one or more copies of the retroviral genome becomes integrated into the host genome [PubMed12876457].

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 9 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 Retroviral matrix 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 9 hidden Markov models representing the Retroviral matrix proteins superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
