                ANNOUNCING PFAM RELEASE 13.0

Pfam is a collection of protein domain family alignments which were
constructed semi-automatically using profile hidden Markov models. Pfam
families contain functional annotation and cross-references to other
databases.  Query sequences can be searched against the Pfam library of
profile hidden Markov models at the web sites below.

Pfam 13.0 contains 7426 families.  75% of proteins in SWISSPROT 42.12
and TrEMBL 25.12 have at least one match to a Pfam family.
