UniProt Archive (UniParc) is part of

UniParc contains only protein sequences. All other information about
the protein must be retrieved from the source databases using the
database cross-references. Each unique sequence is stored only once
with a stable identifier. The format of the identifier is UPI followed
by ten hexadecimal numbers, e.g.
UPI000000000A.
UniParc proteins are linked to their source databases by database
cross-references. Each cross-reference links one protein in UniParc to
an accession number in a source database. The database cross-reference
is active as long as the sequence identified by the source accession
number remains unchanged. When the sequence is modified or removed in
the source database, the cross-reference from UniParc becomes inactive.
Active cross-reference can be used to directly access the source
databases but inactive cross-references can only be used to access
sequences archives, such as the
Sequence Version Archive.
UniParc is available for text- and sequence-based searches. Sequences,
which are no longer part of any source database, are excluded from
sequence-based searches, but they are available for text-based
SRS
searches. Performing a similarity search against UniParc is equivalent
to performing the same search against all databases cross-referenced in
UniParc, as UniParc contains all proteins from its source databases.
Sequence similarity searches can be done using
FASTA,
BLAST or
Mpsrch.
