Domaini

The second transmembrane domain has been proposed to cross only half of the lipid bilayer and to loop back into the cytosol, so that the domains on each side of this domain are both found on the cytosolic face of the membrane. The cytosolic loop may form an ion-conducting pore.

Sequence similaritiesi

Belongs to the TMEM38 family.Curated
