GABARAPL1 (Gamma-aminobutyric acid receptor-associated protein-like 1), also known as ATG8L1. is a member of the ATG8 protein family, which plays critical roles in autophagy—a conserved cellular process for degrading and recycling cytoplasmic components. This ubiquitin-like protein is structurally homologous to LC3 and GABARAP subfamily members, sharing a conserved ubiquitin-fold domain that facilitates interactions with autophagy-related (ATG) proteins and membrane lipids. GABARAPL1 is involved in multiple stages of autophagy, including autophagosome formation, cargo recognition, and vesicle fusion. Beyond its canonical role in autophagy, it participates in membrane trafficking, receptor internalization, and cellular stress responses, linking it to pathologies such as cancer, neurodegeneration, and metabolic disorders.
Recombinant GABARAPL1 refers to the protein produced through genetic engineering, typically expressed in bacterial or mammalian systems for functional studies. Researchers utilize it to investigate molecular mechanisms of autophagy, protein-protein interactions, and post-translational modifications (e.g., lipidation) essential for membrane association. Its recombinant form enables controlled in vitro experiments, structural studies (e.g., crystallography or NMR), and drug screening targeting autophagy pathways. Tagged versions (e.g., His-tag, GFP) simplify purification and visualization in cellular assays. Studies have highlighted its differential expression in tumors and crosstalk with signaling pathways like mTOR, making it a potential biomarker or therapeutic target. However, functional redundancy within the ATG8 family necessitates careful interpretation of experimental data. Recombinant GABARAPL1 remains a vital tool for dissecting autophagy-related cellular dynamics and disease mechanisms.
