description: Domain observed N-terminal to the pPIWI_RE domain module. PIWI/Argonaute modules are typically
  N-terminally fused to the PTND1 and PTND2 domains [[cite:PUB00091015]], pPIWI_RE_X may represent an
  ancestral version of these domains or represent a N-terminal innovation predating the emergence of PTND1
  and PTND2 [[cite:PUB00091016]].
