Transmembrane protein 119, Tmem119, is a bone formation related factor that belongs to a group of bone morphogenetic proteins (BMPs). It is a class IA single pass transmembrane protein1.
Tmem119 promotes the differentiation of myoblasts (embryonic precursors of muscle cells) into osteoblasts and plays a role in numerous BMP signaling pathways1,2.
Tmem119 is uniquely expressed in microglia cells and it is therefore used as a microglia-specific homeostatic marker that can assist in differentiating microglia cells from peripherally derived macrophages in the brain3. This marker is very important for diagnosing CNS disease: monocytes/macrophages are key cellular modulators of brain homeostasis. In the healthy brain resident microglia are the predominant macrophage cell population but when the blood-brain barrier is leaking peripheral monocytes/macrophages can infiltrate the brain and participate in CNS disease pathogenesis. Distinguishing these two monocytesmacrophages populations is often challenging and hence the existence of a highly expressed and robust microglia marker such as Tmem119 is very important4.
Species reactivity key:
Anti-TMEM119 (extracellular) Antibody (#ANR-175) is a highly specific antibody directed against an epitope of the mouse protein. The antibody can be used in western blot and indirect live cell flow cytometry. It has been designed to recognize TMEM119 from rat and mouse samples. The antibody will not recognize the protein from human samples.
