The UniProt Protein DAS Server
The server also gives access to Gene Ontology Annotation of UniProt sequences (GOA) and theoretical tryptic digests of protein sequences in UniProt and IPI. An extremely useful resource for users of DAS is the DAS Registration Server that supports registry and discovery of DAS services. The datasources provided by the UniProt DAS server are all registered with this service. This is a complete re-write of the UniProt DAS server. The server is now based upon the MyDas Java DAS Server Framework.
The data sources (DSN) available from the DAS reference server have been separated and extended. The previous
version of the UniProt DAS server included only one DSN: 'aristotle'. This DSN is still available
for services that rely upon it, with the same functionality as provided previously,
however the three components of aristotle (UniProt, UniParc and IPI)
are also available as separate data sources.
Please Note
The Aristotle das source will be taken offline at the beggining of 2010.Another major change in the service is the use of the UniProt Java Remoting API (UniProtJAPI) to retrieve data from the UniProt Knowledgebase. This is used to provide sequence information for the UniProt, UniParc and IPI data sources and to retrieve the information for constructing features served from the UniProt and UniParc data sources. The primary sources of the data avialable from the UniProt DAS reference server include: UniProt/Swiss-Prot, UniProt/TrEMBL, UniParc (The UniProt Archive), IPI (The International Protein Index) and GOA (Gene Ontology annotation of UniProt)
The individual data sources, together with some example queries are presented in the table below:

The distributed annotation system (DAS) is a client-server system in which a single client
integrates information from multiple servers. The UniProt DAS server provides access to sequence
and annotation from UniProt, UniParc and IPI. Researchers can then provide annotation of their
own results in the context of UniProt annotation, IPI annotation and UniParc cross references
through the use of suitable DAS client such as
