Description : (at4g21980 : 140.0) Encodes APG8, a component of autophagy conjugation pathway. Delivered to the lumens of vacuole under nitrogen-starvation condition. Highest expression in flowers. mRNA abundance increased during dark-induced carbon starvation. Predominantly cytoplasmic with or without N starvation. Upon concanamycin A the protein accumulates in the central vacuole as punctuate structures that resemble autophagic bodies. This localization is more abundant upon N starvation.; AUTOPHAGY 8A (APG8A); FUNCTIONS IN: APG8-specific protease activity, APG8 activating enzyme activity, Atg8 ligase activity; INVOLVED IN: autophagy; LOCATED IN: vacuolar lumen, autophagic vacuole, cytoplasm; EXPRESSED IN: 24 plant structures; EXPRESSED DURING: 15 growth stages; CONTAINS InterPro DOMAIN/s: Light chain 3 (LC3) (InterPro:IPR004241); BEST Arabidopsis thaliana protein match is: Ubiquitin-like superfamily protein (TAIR:AT4G04620.2); Has 1531 Blast hits to 1529 proteins in 269 species: Archae - 0; Bacteria - 0; Metazoa - 726; Fungi - 172; Plants - 305; Viruses - 3; Other Eukaryotes - 325 (source: NCBI BLink). & (reliability: 280.0) & (original description: no original description)
