ThreaDom (Threading-based Protein Domain Prediction)
is a template-based algorithm for protein domain boundary prediction.
Given a protein sequence, ThreaDom first threads the target through
the PDB library to identify protein template that have similar structure fold.
A domain conservation score (DCS) will be calculated for each residue which
combines information from template domain structure, terminal and internal gaps
and insertions.
Finally, the domain boundary information is derived from the DCS profile
distributions.
ThreaDom is designed to predict both continuous and discontinuous domains.
Note:
We recently developed three new servers for protein domain modeling:
- ThreaDomEx:
An extended algorithm of ThreaDom with the ability for modeling
discontinuous domains;
- FUpred:
Predicting domain boundary from contact-map, suitable for
proteins lacking homologous templates in PDB;
- DEMO:
Assemble individual domain structures into full-length protein model.
