LMAN1, also known as ERGIC-53, is a transmembrane receptor that binds to high-mannose containing soluble glycoproteins in the ER and helps package them into COPII vesicles for trafficking to the ERGIC and Golgi. Identified cargo include SERPINA (alpha1-antitrypsin) and the cathepsins CTSC and CTSZ, among others (Nyefeler et al, 2008; Appenzeller et al, 1999; reviewed in Hauri et al, 2000; Szul and Sztul, 2011). LMAN1 itself is concentrated into COPII vesicles through interaction with components of the COPII coat (Kappeler et al, 1997; reviewed in Dancourt and Barlowe, 2010). Other LMAN family proteins, which include LMANL1, LMAN2 and LMAN2L, also bind glycosylated ER cargo proteins, although the lectin specificities vary (Kamiya et al, 2005; Kamiya et al, 2007; Reiterer et al, 2010; reviewed in Dancourt and Barlowe, 2010).
