ATG13 (Autophagy Related 13) is a critical gene involved in the initiation of autophagy, a fundamental cellular process responsible for degrading and recycling damaged organelles, protein aggregates, and intracellular pathogens. The protein encoded by ATG13 serves as a key regulator of the ULK1 complex, which orchestrates the early steps of autophagosome formation. This gene is particularly important in neuronal cells, where proper autophagy function is essential for maintaining synaptic homeostasis and clearing pathological protein aggregates associated with neurodegenerative diseases including Parkinson's disease, Huntington's disease, ALS, and Alzheimer's disease.
ATG13 encodes a critical regulator of autophagy, the cellular process for degrading and recycling damaged organelles and protein aggregates. ATG13 is part of the ULK1 complex (ULK1-ATG13-FIP200-ATG101) that initiates autophagosome formation. This complex responds to cellular energy status (AMPK activation) and nutrient availability (mTOR inhibition) to trigger autophagy. In neurons, ATG13 is essential for clearing protein aggregates and maintaining synaptic homeostasis.
Widely expressed in all tissues, with high expression in brain, particularly in neurons and glial cells. Upregulated under cellular stress conditions.
