9.B.408. The DUF401 (DUF401) Family This family consists of proteins of unknown function that have about 400 aas and about 12 TMSs.They may have distant relationships with the DMT superfamily, especially 2.A.7.28.5, 7, and 4, with comparison scrores of 0.0007, 0.002 and 0.019. They might have 5 + 2 + 5 TMS arrangements.
