Autophagy-related 9 (Atg9) encodes an integral membrane protein acting as a membrane carrier for forming autophagosomes. It regulates TOR and JNK signaling pathways via autophagy. [Date last reviewed: 2019-07-11]
Gene Group (FlyBase)
AUTOPHAGY-RELATED GENES -
The Autophagy-related genes (Atg), characterized extensively in yeast, are a set of approximately twenty evolutionarily conserved genes required for autophagy. Autophagy (specifically, macroautophagy) is the process of bulk degradation of cytoplasmic material. It takes place by the assembly of a double membrane vesicle, the autophagosome, which delivers cargo to the lysosome for recycling. (Adapted from FBrf0219844 and FBrf020902).
Summary (Interactive Fly)

a vesicular transmembrane protein that is a constituent of autophagic vesicles and is required for oxidative stress-induced JNK activation

Model Confidence:
  • Very high (pLDDT > 90)
  • Confident (90 > pLDDT > 70)
  • Low (70 > pLDDT > 50)
  • Very low (pLDDT < 50)

AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Some regions with low pLDDT may be unstructured in isolation.

Testis-specificity index

The testis specificity index was calculated from modENCODE tissue expression data by Vedelek et al., 2018 to indicate the degree of testis enrichment compared to other tissues. Scores range from -2.52 (underrepresented) to 5.2 (very high testis bias).
