Accession ID Name Pfam Type
PF13721 SecD export protein N-terminal TM region family

This domain appears to be the fist transmembrane region of the SecD export protein. SecD is directly involved in protein secretion and important for the release of proteins that have been translocated across the cytoplasmic membrane.
