| Short Name | DUF1980 |
| description | Members of this occur in gene pairs with members of . The N-terminal region contains several predicted transmembrane helix regions while the few invariant residues (G, CxxD, and W) occur in the C-terminal region. Members of this family are found in a set of prokaryotic hypothetical proteins. Their exact function has not, as yet, been defined. |
