Abstract

UBA domains are a commonly occurring sequence motif of approximately 45 amino acid residues that are found in diverse proteins involved in the ubiquitin/proteasome pathway, DNA excision-repair, and cell signalling via protein kinases [PubMed12079361]. HHR23A, the human homologue of yeast Rad23A is a nucleotide excision-repair protein that contains both an internal and a C-terminal UBA domain. The fold of the UBA domain consists of a compact three-helical bundle with a right-handed twist, and have a conserved hydrophobic surface patch for protein-protein interactions. UBA-like domains can be found in other proteins as well, such as the TS-N domain in the elongation factor Ts (EF-Ts), which catalyses the recycling of the GTPase EF-Tu required for the binding of aminoacyl-tRNA top the ribosomal A site [PubMed11744709]; and the C-terminal domain of TAP/NXF1, which functions in nuclear export through the interaction of its UBA-like domain with FG nucleoporins [PubMed12581645].

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 37 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 UBA-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 37 hidden Markov models representing the UBA-like superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
