Sec61beta family
This family consists of homologs of Sec61beta - a component of the Sec61/SecYEG protein secretory system. The domain is found in eukaryotes and archaea and is possibly homologous to the bacterial SecG. It consists of a single putative transmembrane helix, preceded by a short stretch containing various charged residues; this arrangement may help determine orientation in the cell membrane.
