description: This repeat has no known function. It is about 35 amino acids long and found in up to 18
  copies in some proteins. This family appears to be greatly expanded in plants. This repeat occurs in
  PET309 [swissprot:P32522] that may be involved in RNA stabilisation [[cite:PUB00001271]]. This domain
  occurs in crp1 that is involved in RNA processing [[cite:PUB00001258]]. This repeat is associated with
  a predicted plant protein [swissprot:O49549] that has a domain organisation similar to the human BRCA1
  protein. The repeat has been called PPR [[cite:PUB00017589]].
