Phagocytosis is required for a broad range of physiological functions, from pathogen defense to tissue homeostasis, but mechanisms required for phagocytosis of diverse substrates remain incompletely understood. Here, we develop a rapid magnet-based phenotypic screening strategy, and perform eight genome-wide CRISPR screens in human cells to identify genes regulating phagocytosis of distinct substrates. After validating select hits in focused mini-screens, orthogonal assays and primary human macrophages, we demonstrate that 1) the previously-uncharacterized gene NHLRC2 is a central player in phagocytosis, regulating RhoA-Rac1 signaling cascades that control actin polymerization and filopodia formation, 2) very long chain fatty acids are essential for efficient phagocytosis of certain substrates, and 3) the previously-uncharacterized Alzheimer’s disease-associated gene TM2D3 can preferentially influence uptake of amyloid-β aggregates. These findings illuminate new regulators and core principles of phagocytosis, and more generally establish an efficient method for unbiased identification of cellular uptake mechanisms across diverse physiological and pathological contexts.
