Autophagy receptor for glycogen; cytosolic receptor for glycogen that mediates glycophagy, the autophagy of glycogen; induced during prolonged nitrogen starvation and highly expressed during sporulation, both glycophagy-inducing conditions; expression directly regulated by Ume6p, a metabolic and meiotic transcriptional regulator; contains a glycogen-binding domain (GBD) and an Atg8 family-interacting motif (AIM) proposed to facilitate sequestration of glycogen by autophagic isolation membranes
