REACH authorisation
Abcam has not and does not intend to apply for the REACH Authorisation of customers' uses of products that contain European Authorisation list (Annex XIV) substances.
It is the responsibility of our customers to check the necessity of application of REACH Authorisation, and any other relevant authorisations, for their intended uses.
Lysate preparation:
Our lysates are made using RIPA buffer to which we add a protease inhibitor cocktail and phosphatase inhibitor cocktail (ratio: 300:100:10).
This means that the protein of interest is denatured.
If you require a native form of the protein please use the live cell version. Please refer to our lysis protocol for further details on how our lysates are prepared.
User storage instructions:
Lyophilizate may be stored at 4°C. After reconstitution, store at -20°C for short-term storage or -80°C for long-term storage.

ATG4A also known as Autophagin 1 is a cysteine protease with a mass of approximately 52 kDa. It plays a critical role in the autophagy pathway by cleaving LC3 and other Atg8 homologs facilitating their conjugation to phosphatidylethanolamine on the autophagosome membrane. This protein is expressed in various tissues including the liver and skeletal muscle indicating its involvement in diverse physiological processes.
Biological function summary
ATG4A contributes essential functions to cellular homeostasis by participating in autophagosome formation. As part of the group of Atg proteins it collaborates with other members to modulate the autophagy machinery. ATG4A's enzymatic activity provides the necessary steps for processing LC3 transforming it into a form that allows lipidation and incorporation into autophagic vesicles.
Pathways
ATG4A is integral to the autophagy pathway a catabolic process important for cell survival under stress conditions. It interacts with proteins such as ATG7 and ATG3 within this pathway playing a significant role in the early stages of autophagosome maturation. The interactions ensure proper recycling of cellular materials and its efficient function impact cellular metabolism and stress responses.
Disruptions in ATG4A function have been linked to neurodegenerative diseases and cancer. Aberrant autophagy processes involving ATG4A can lead to protein aggregation disorders such as Alzheimer’s disease where proper proteostasis is compromised. Also in certain cancers altered ATG4A activity can influence tumor growth often through modulation of metabolic pathways and interactions with proteins like Beclin 1 which regulate autophagic responses.
