Under normal nutritional conditions, G-protein coupled receptors can control autophagy by regulating the degradation of key autophagic regulator Atg14L through ZBTB16-mediated ubiquitination and proteasome degradation.
Atg43 serves as a selective autophagy receptor by tethering isolation membranes to mitochondria to promote mitophagy and plays a mitophagy-independent role that facilitates normal cell growth in fission yeast.
Autophagic cargo receptors recruit the E3-like enzyme for Atg8 lipid conjugation to the cargo and thereby promote local formation of Atg8-positive autophagosomal membranes.
Defense-related selective autophagy mediated by the antimicrobial autophagy cargo receptor NBR1/Joka2 is diverted to pathogen penetration sites to restrict plant colonization by the oomycete pathogen Phytophthora infestans.
Measurement of post-translational modifications in primary macrophages infected with Mtb revealed phosphorylation of TAX1BP1, an autophagy receptor that enables full maturation of the Mtb autophagosome.
