The GABARAPL2 gene encodes a member of the ATG8 (autophagy-related 8) protein family, also known as GATE-16 (Golgi-Associated ATPase Enhancer of 16 kDa). GABARAPL2 plays crucial roles in autophagosome formation, cargo selection, and membrane fusion events during autophagy. As a ubiquitin-like protein, it undergoes similar conjugation reactions as LC3/GABARAP family members.
