TREM-2 Protein, Cynomolgus (HEK293, His)

TREM-2 Protein forms a receptor signaling complex with TYROBP, mediating signaling and cell activation upon ligand binding. It acts as a receptor for amyloid-beta protein 42, facilitating its uptake and degradation by microglia, resulting in microglial activation, proliferation, migration, apoptosis, and cytokine expression. Additionally, TREM-2 serves as a receptor for lipoprotein particles and apolipoproteins, enhancing their uptake in microglia. It binds phospholipids and regulates microglial proliferation, phagocytosis of apoptotic neurons, and response to oxidative stress. Furthermore, TREM-2 suppresses PI3K and NF-kappa-B signaling, promotes anti-apoptotic NF-kappa-B signaling during oxidative stress, and plays a role in microglial MTOR activation and metabolism. It is involved in age-related changes in microglial numbers and triggers immune responses in macrophages and dendritic cells. TREM-2 also mediates cytokine-induced multinucleated giant cell formation and is implicated in osteoclast differentiation. The protein interacts with TYROBP, and this interaction is crucial for stabilizing the TREM-2 C-terminal fragment.
