Procollagen VII trimers, which are too large for standard COPII vesicles, are packaged into larger transport vesicles through interaction with the transmembrane accessory proteins MIA3 (also known as TANGO1) and MIA2 (also known as CTAGE5). MIA3 interacts with collagen through its lumenal SH3 domain and interacts with SEC23 and SEC24 through the proline rich domain (Saito et al, 2009; reviewed in Malhotra and Erlmann, 2011; Malhotra et al, 2015).
