Predicted to enable several functions, including GABA receptor binding activity; Tat protein binding activity; and ubiquitin protein ligase binding activity. Predicted to be involved in autophagosome assembly; autophagy of mitochondrion; and cellular response to nitrogen starvation. Predicted to act upstream of or within autophagy. Predicted to be located in several cellular components, including Golgi apparatus; cell body; and dendrite. Predicted to be active in autophagosome membrane and cytosol. Predicted to colocalize with mitochondrion. Is expressed in axial skeleton; ganglia; sensory organ; trigeminal nerve; and urinary system. Orthologous to human GABARAPL1 (GABA type A receptor associated protein like 1). [provided by Alliance of Genome Resources, Apr 2022]
