Full description
A protein families and domains database maintained at the Swiss
Institude for Bioinformatics. It consists of biologically significant
sites, patterns and profiles that help to reliably identify to which
known protein family (if any) a new sequence belongs. PROSITE currently
contains patterns and profiles specific for more than a thousand
protein families or domains. Each of these signatures comes with
documentation providing background information on the structure and
function of these proteins.
