Domain definition

For those wanting it quick: flat file with manual domain parse is here.

Proteins are composed of domains. Domains are usually defined as globular units in protein structures. Domains are somewhat separate from each other spatially and can recombine with each other in evolution to form various proteins. Each domain frequently carries out its own function, or the functional site may be formed at the domain interface. Analysis of domains is essential for understanding of proteins. However, while everyone agrees on the domain importance, opinions differ greatly about the criteria for domain definition, and existing software tools are inconsistent with each other in domain parse. Researchers think about domains from the position of structural compactness, sequence similarity and continuity, evolutionary origin, folding or function. Different criteria lead to different domain definitions. Nevertheless, our experience with protein sequence-structural analysis indicates that it might be possible to bring these criteria together for a biologically reasonable domain parse. We applied our conceptual view on protein domains to CASP8 targets. Domains defined here correspond to structurally compact evolutionary modules.

To define domains in a target we looked for similarity to other protein sequences and structures and self-similarity (internal duplications), structural compactness (globularity), presence of a hydrophobic core, and took into account sequence continuity. To define precise boundaries between domains, we inspected side-chain orientations and their interactions with domains. Domain parses by DOM, DOMAK, DomainParser, PDP and PUU, were also analyzed. We tried to attribute all residues in PDB to a domain rather than excluding extensions, loops and linkers, because if the residue is ordered, it should contribute to assessment of predictions. In some targets (e.g. T0435), certain regions protruded away from the PDB chain. These regions were frequently involved in a domain swap. In such cases, we defined globular domains with a swap, and also defined truncated domains with a swapped region removed. The following targets were affected by this:

In other cases, protruding regions did not participate in swaps, but were interacting with other chains in the crystals, e.g. in T0388. We removed such regions in domain definition to check whether the shorter domain is predicted more accurately. Text file with domain boundaries for all targets can be downloaded from here.

We did not take into account server predictions in defining domains, only sequence, structural and evolutionary considerations about targets were used. It might not be necessary to use these evolutionary domains for evaluation of all targets. See the discussion of whole chain vs. domain evaluation. In summary, comparison of domain-based predictions with whole chain predictions reveals that the following targets require domain-based evaluation: T0397, T0405, T0407, T0409, T0416, T0419, T0429, T0443, T0457, T0462, T0472, T0478, T0487, T0496, T0501, T0504, T0510, as for these targets server predictions for whole chains are much inferior to individual domain predictions. Only these targets are evaluated as domains in our combined domain evaluation tables. Predictions for other targets follow the general trend, are of a more similar quality for 'domain' and 'whole chain' and thus domain-based evaluation may not be necessary for them. Thus other targets are evaluated as whole chains in combined domain evaluation tables. These targets are considered to be single-domain proteins for evaluation. Although some of these targets are multi-domain proteins evolutionarily, domains do not move relatively to each other, are of the same prediction difficulty. Nevertheless, we compute evaluation scores on all domains shown in the table below, and these scores are available from individual target pages, e.g. T0497 page shows evaluation of whole chain (T0497), swapped domain (T0497_1s) and truncated domain with a swapped region removed (T0497_1).

In the table below, domains are marked by "_" followed by a domain number and preceded by a target name; "s" after the domain number denotes a swapped domain. Whole chains (no "_" in name) are given to show the residue range and mapping between target and PDB. Links to PyMOL scripts with domain definitions by various workers and programs are provided as well.
