CC -!- FUNCTION: Serine/threonine protein kinase involved in the cytoplasm to
CC vacuole transport (Cvt) and found to be essential in autophagy, where
CC it is required for the formation of autophagosomes. Involved in the
CC clearance of protein aggregates which cannot be efficiently cleared by
CC the proteasome. Required for selective autophagic degradation of the
CC nucleus (nucleophagy) as well as for mitophagy which contributes to
CC regulate mitochondrial quantity and quality by eliminating the
CC mitochondria to a basal level to fulfill cellular energy requirements
CC and preventing excess ROS production. Also involved in endoplasmic
CC reticulum-specific autophagic process, in selective removal of ER-
CC associated degradation (ERAD) substrates. Plays a key role in ATG9 and
CC ATG23 cycling through the pre-autophagosomal structure and is necessary
CC to promote ATG18 binding to ATG9 through phosphorylation of ATG9.
CC Catalyzes phosphorylation of ATG4, decreasing the interaction between
CC ATG4 and ATG8 and impairing deconjugation of PE-conjugated forms of
CC ATG8. {ECO:0000250|UniProtKB:P53104}.
