Ligands: MA4, NAG Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function MPEG1_MOUSE Plays a key role in the innate immune response following bacterial infection by polymerizing and inserting into the bacterial surface to form pores (PubMed:26402460). By breaching the surface of phagocytosed bacteria, allows antimicrobial effectors to enter the bacterial periplasmic space and degrade bacterial proteins such as superoxide dismutase sodC which contributes to bacterial virulence (PubMed:30249808). Shows antibacterial activity against a wide spectrum of Gram-positive, Gram-negative and acid-fast bacteria (PubMed:23257510, PubMed:23753625, PubMed:26402460). Reduces the viability of the intracytosolic pathogen L.monocytogenes by inhibiting acidification of the phagocytic vacuole of host cells which restricts bacterial translocation from the vacuole to the cytosol (PubMed:26831467). Required for the antibacterial activity of reactive oxygen species and nitric oxide (PubMed:26402460).
