complex(p(HGNC:ATG12), p(HGNC:ATG5))
In the first arm of the Atg conjugation system, phagophore membrane elongation is triggered through the sequential action of an E1-like protein (Atg7) and an E2-like protein (Atg10) leading to an isopeptide linkage between the C-terminal glycine the UBL protein Atg12 and a lysine residue of Atg5 (Figure 2b).

These Atg12-Atg5 conjugates are further cross-linked to Atg16 to form a large (~350 kDa) multimeric complex, which has been thought to act as a structural support for membrane expansion [15]. PubMed:18930136
More recent work has demonstrated that the Atg12-Atg5 conjugate can function as an E3-like enzyme in the second arm of the Atg conjugation cascade to promote lipidation of Atg8 [16] PubMed:18930136
