The SEC61 complex is a major component of the endoplasmic reticulum(ER) translocation site(PMID: 7720858). This complex is composed of three subunits: SEC61alpha, SEC61beta and SEC61gamma. SEC61alpha is a polytopic integral membrane protein. It is a core component of the ER translocation complex, playing a crucial role in the insertion of secretory and membrane polypeptides into the ER.
