TREM2: Proteins and Enzymes

TREM2 (Triggering Receptor Expressed on Myeloid cells 2) is a transmembrane protein that is expressed on newly differentiated and alternatively activated tissue macrophages, immature myeloid dendritic cells, and osteoclasts. TREM2 interacts with and modifies signaling through dendritic cell and osteoclast Plexin A1, a semaphorin receptor. It is active in several settings that involve membrane fusion, including phagocytosis of microbes by macrophages and apoptotic neurons by microglia, and ...
