description: Domain occurs as one or more copies in bacterial and eukaryotic proteins. These are membrane
  proteins of four TM regions, two appearing in each of the two copies when both are present. Many of
  the latter members also carry the sodium/calcium exchanger protein family [pfam:PF01699], which have
  multipass membrane regions.
