IFNGR1 / CD119 Protein (His tag) (recombinant mouse)

Activity: Measured by its ability to bind with recombinant mouse IFNG-Fc in a functional ELISA. Protein Construction: A DNA sequence encoding the mouse IFNGR1 (P15261) extracellular domain (Met 1-Asp 253) was expressed, with a polyhistidine tag at the C-terminus. Sequence: Met 1-Asp 253. Fusion tag: C-His Endotoxin: < 1.0 EU per µg of the protein as determined by the LAL method. Apparent Molecular Mass: 40-45 kDa. Protein function: The cluster of differentiation (CD) system is commonly used as cell markers in immunophynotyping. Different kinds of cells in the immune system can be identified through the surface CD molecules which associating with the immune function of the cell. There are more than 320 CD unique clusters and subclusters have been identified. Some of the CD molecules serve as receptors or ligands important to the cell through initiating a signal cascade which then alter the behavior of the cell. Some CD proteins do not take part in cell signal process but have other functions such as cell adhesion. CD119 (cluster of differentiation 119), also known as IFNGR1 ( interferon gamma receptor 1), is part of the heterodimeric gamma interferon receptor which consists of IFNGR1 (CD119) and IFNGR2. The IFNGR1 gene encodes the ligand-binding chain (alpha) of the interteron receptor while IFNGR gene encodes the non-ligand binding partner. The ability of the interferon-gamma was achieved through binding to the interferon receptor CD Protein function: Associates with IFNGR2 to form a receptor for the cytokine interferon gamma (IFNG) (PubMed:2530582, PubMed:2532365, PubMed:2137461, PubMed:2531896, PubMed:2530216). Ligand binding stimulates activation of the JAK/STAT signaling pathway. [The UniProt Consortium]
