Store lyophilized/reconstituted at -20°C; once reconstituted make aliquots to avoid repeated freeze-thaw cycles. Please remember to spin the tubes briefly prior to opening them to avoid any losses that might occur from material adhering to the cap or sides of the tube.
For reconstitution add 0.5 mL of sterile water.
Specific Species Reactivity: Chlamydomonas reinhardtii, Chlorococcum dorsiventrale
ATG4 is a cysteine protease central to the autophagy pathway in plants. It processes ATG8 by cleaving a C terminal extension to expose a glycine required for conjugation to phosphatidylethanolamine, enabling formation and maturation of autophagosomes. ATG4 also deconjugates ATG8 from membranes, allowing recycling and fine tuning of autophagic flux. Plant ATG4 activity is modulated by redox status and interacts with regulatory factors to adjust autophagy during nutrient limitation, senescence, and stress such as drought, salinity, and pathogen challenge. Multiple ATG4 isoforms can provide substrate specificity for different ATG8 variants, influencing selective autophagy of organelles and protein aggregates. Genetic studies in Arabidopsis and crops link ATG4 to growth maintenance, stress tolerance, and nutrient remobilization by sustaining efficient cellular recycling.
