Function
ATG-16.2 is likely a component of the ATG-5-ATG-12-ATG-16.1/ATG-16.2 complex, which is recruited to the preautophagosomal membrane and interacts with LGG-2 to facilitate autophagosome formation. It plays a role in recruiting lipidated LGG-1, likely to the autophagosome membrane, to further promote autophagosome formation. Furthermore, its association with ATG-5 is essential for the nucleation of LGG-1 positive autophagosomes. Although its role in autophagosome formation may differ from that of ATG-16.2, it functions partially redundantly with ATG-16.1 to regulate autophagic processes. In a DAF-18/PTEN- and DAF-16/FOXO-dependent manner, ATG-16.2 is required for maintaining the number of germ stem cell progenitors in the gonad during the later stages of larval development.
