MIA2 (also known as CTAGE5) and MIA3 form heterodimers through their second coiled coil domains and interact with inner coat proteins SEC24C and SEC23A through their proline-rich domains. In this way, the MIA3 and MIA2 concentrate procollagen VII at ER exit sites (Saito et al, 2011; reviewed in Malhotra and Erlmann, 2011; Malhotra et al, 2015).
