The identification and characterization of noncanonical functions within the autophagy pathway have unveiled intricate cellular processes, including LC3-associated phagocytosis (LAP) and LC3-associated endocytosis (LANDO). These phenomena play pivotal roles in the conjugation of ATG8 with single-membrane phagosomes and endosomes, shedding light on the dynamic interplay between autophagy and cellular homeostasis. Here, we present detailed protocols for both qualitative and quantitative assessment of LAP, including immunofluorescence, flow cytometry, and Western blotting of isolated LAPosomes. Additionally, the protocol for the evaluation of LANDO through immunofluorescent detection of receptor recycling is outlined. The methodologies presented herein serve as a practical guide for researchers seeking to unravel the intricacies of LAP and LANDO. By providing step-by-step instructions, accompanied by insights into potential challenges and optimization strategies, this chapter aims to empower investigators in the exploration of these noncanonical functions of autophagy proteins.
