HEK293 human embryonic kidney cell line transfected with either (A) human TMEM119 or (B) irrelevant protein, and eGFP, was stained with Mouse anti-human TMEM119 monoclonal antibody (Catalog # MAB10313) followed by Allophycocyanin-conjugated anti-Mouse IgG Secondary Antibody (F0101B). Quadrant markers were set based on control antibody staining (MAB002, data not shown). Staining was performed using our Staining Membrane-Associated Proteins protocol.

TMEM119 in Human Brain Cortex Tissue.

TMEM119 was detected in immersion fixed paraffin-embedded sections of human brain cortex tissue using Mouse Anti-Human TMEM119 Monoclonal Antibody (Catalog # MAB10313) at 5 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Mouse IgG VisUCyte™ HRP Polymer Antibody (VC001). Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (CTS013). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to gilal cells. Staining was performed using our IHC Staining with VisUCyte HRP Polymer Detection Reagents protocol.

Background: TMEM119

TMEM119 (Transmembrane Protein 119, also known as Osteoblast Induction Factor or OBIF), is an approximately 38-kDa type 1 transmembrane protein that is predominantly expressed in osteoblasts and is upregulated during osteoblastic differentiation (1, 2). TMEM119 is also expressed in a cell line of microglia, and TMEM119 immunoreactivity is observed in a specific subset of microglia in brains of neurodegenerative diseases, such as Alzheimers disease (3). Mature human TMEM119 consists of a 71 amino acid (aa) extracellular domain (ECD), a 21 aa transmembrane segment, and a 166 aa cytoplasmic domain. Within the ECD, human TMEM119 shares 78% and 75% aa sequence identity with mouse and rat TMEM119, respectively. TMEM-119 is involved in the osteoblast differentiation and bone development by acting as a ligand and has been reported to contribute to the proliferation, migration, and invasion of osteosarcoma cells, as well as functioning as an oncogene in osteosarcoma (3, 4).
