Function

GBRL2_HUMAN Ubiquitin-like modifier involved in intra-Golgi traffic. Modulates intra-Golgi transport through coupling between NSF activity and SNAREs activation. It first stimulates the ATPase activity of NSF which in turn stimulates the association with GOSR1 (By similarity). Involved in autophagy. Plays a role in mitophagy which contributes to regulate mitochondrial quantity and quality by eliminating the mitochondria to a basal level to fulfill cellular energy requirements and preventing excess ROS production. Whereas LC3s are involved in elongation of the phagophore membrane, the GABARAP/GATE-16 subfamily is essential for a later stage in autophagosome maturation.^[1] ^[2]

Publication Abstract from PubMed

Autophagy is a fundamental homeostatic process in eukaryotic organisms, fulfilling essential roles in development and adaptation to stress. Among other factors, formation of autophagosomes critically depends on proteins of the Atg8 (autophagy-related protein 8) family, which are reversibly conjugated to membrane lipids. We have applied X-ray crystallography, nuclear magnetic resonance spectroscopy, and molecular dynamics simulations to study the conformational dynamics of Atg8-type proteins, using GATE-16 (Golgi-associated ATPase enhancer of 16 kDa), also known as GABARAPL2, as a model system. This combination of complementary approaches provides new insight into a structural transition centered on the C-terminus, which is crucial for the biological activity of these proteins.
