Abstract

This entry represents a structural domain with a complex fold consisting of several coiled beta-sheets. This domain exists as a duplication, consisting of a tandem repeat of two similar structural motifs. These domains can be found in:

  • Mss4, which contains a zinc-binding site.
  • Translationally controlled tumour-associated protein TCTP, which contains an insertion of an alpha-helix hairpin, and which lacks a zinc-binding site.
  • The C-terminal MsrB domain of peptide methionine sulphoxide reductase.

Mss4 is a conserved accessory factor for Rab GTPases, which function as ubiquitous regulators of intracellular membrane trafficking [PubMed11258916]. Mss4 acts to promote nucleotide release from exocytic but not endocytic Rab GTPases. Mss4 has a complex fold made of several coiled beta-sheets, and consists of a duplication of tandem repeats of two similar structural motifs. It contains a zinc-binding site.

Other proteins that show structure similarity to Mss4 include the translationally controlled tumour-associated proteins TCTPs, which contains an insertion of an alpha helical hairpin, and lacks the zinc-binding site. TCTPs are a highly conserved and abundantly expressed family of eukaryotic proteins that are implicated in both cell growth and the human acute allergic response [PubMed11473261].

The C-terminal MsrB domain of peptide methionine sulphoxide reductase PilB is structurally similar to Mss4. Methionine sulphoxide reductases protect against oxidative damage that can contribute to cell death. The tandem Msr domains (MsrA and MsrB) of the pilB protein from Neisseria gonorrhoeae each reduce different epimeric forms of methionine sulphoxide [PubMed11938352].

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 8 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 Mss4-like 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 8 hidden Markov models representing the Mss4-like superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
