The following uncharacterized proteins have been shown  to share regions of
Yeast hypothetical protein YBR187w.
Fission yeast hypothetical protein SpAC17G8.08c.
Mouse protein pFT27.
Synechocystis strain PCC 6803 hypothetical protein sll0615.
These are hydrophobic proteins of 200 to 320 amino acids that seem to contain
six or seven transmembrane domains. As a signature pattern, we selected a
conserved region which seems, in the eukaryotic proteins of this family, to
directly follow the second transmembrane domain.
