Probably acts as an adapter for ATPase cdc-48.1 and/or cdc-48.2, conferring substrate specificity. Involved in the lysosomal clearance of cellular material in diet restricted conditions (PubMed:30595383). Interacts with cdc-48.1 (via N-terminus) and cdc-48.2 (via N-terminus). Expressed in the pharynx and some head neurons. Expressed at L4 larval stage and in adults. Expressed at low levels in embryos and between the L1 and L3 larval stages. Up-regulated in response to starvation (at protein level). Reduced lifespan (PubMed:30595383). Prolonged expression of the lysosomal protein glo-1 12 hours after starvation (PubMed:30595383).
