Involved in negative regulation of neuron apoptotic process and reticulophagy. Acts upstream of or within mitophagy and white fat cell differentiation. Located in cis-Golgi network. Is expressed in several structures, including alimentary system; central nervous system; ganglia; metanephros; and reproductive system. Human ortholog(s) of this gene implicated in hereditary sensory and autonomic neuropathy type 2B. Orthologous to human RETREG1 (reticulophagy regulator 1).
