SEQUENCE SIMILARITIES

Belongs to the ATG8 family.

TISSUE SPECIFICITY

Ubiquitous. Expressed at high levels in the brain, heart, prostate, ovary, spleen and skeletal muscle. Expressed at very low levels in lung, thymus and small intestine.

POST-TRANSLATIONAL MODIFICATION

The precursor molecule is cleaved by ATG4B to form the cytosolic form, GABARAPL2-I. This is activated by APG7L/ATG7, transferred to ATG3 and conjugated to phospholipid to form the membrane-bound form, GABARAPL2-II. ATG4B also mediates the delipidation required for GABARAPL1 recycling when autophagosomes fuse with lysosomes.; The Legionella effector RavZ is a deconjugating enzyme that produces an ATG8 product that would be resistant to reconjugation by the host machinery due to the cleavage of the reactive C-terminal glycine.

SUBCELLULAR LOCATION

Cytoplasmic vesicle. Golgi apparatus.

FUNCTION

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.
