description: This is a family of archaeal proteins, previously known as DUF6995, representing homologues
  of PolB1 Binding Protein 2 (PBP2). PBP2, is a subunit of PolB1 enzyme that is a member of the archaeal
  B-family of DNA polymerases. PBP2 along with PBP1, associate with distinct surfaces of the larger catalytic
  subunit and influence the enzymatic properties of the DNA polymerase [[cite:PUB00154412]]. Members of
  this family adopt a winged helix (HTH) fold.
