Leukocyte Mono Ig-Like Receptor 1/LMIR1/CD300a Protein(C-Fc) (recombinant mouse)

Protein Construction: Recombinant Mouse Leukocyte mono-Ig-like receptor 1 is produced by our Mammalian expression system and the target gene encoding Leu28-Arg183 is expressed with a Fc tag at the C-terminus. Sequence: Leu28-Arg183. Fusion tag: C-Fc Endotoxin: < 1.0 EU per µg as determined by the LAL method. Apparent Molecular Mass: 58-75 kDa. Protein function: LMIR1, also termed CD300a, is a type I transmembrane glycoprotein with a single IgV-like extracellular domain and an extended membrane proximal region that links the immunoglobulin (Ig) and transmembrane domains and belongs to the immunoglobulin superfamily. The intracellular domain of LMIR1 contains several immunoreceptor tyrosine-based inhibition motifs (ITIMs). When cross-linked, it will be tyrosine phosphorylated and capable of recruiting tyrosine phosphatases (SHP-1, SHP-2) and inositol polyphosphate 5-phosphatase, SHIP. LMIR1 will regulate mast cell-mediated inflammatory responses. LMIR1 is broadly expressed on myeloid and lymphoid cells, and its expression is differentially regulated depending on the cell type. Protein function: Inhibitory receptor which may contribute to the down- regulation of cytolytic activity in natural killer (NK) cells, and to the down-regulation of mast cell degranulation (PubMed:12874256, PubMed:12893283, PubMed:16339535). Negatively regulates the Toll-like receptor (TLR) signaling mediated by MYD88 but not TRIF through activation of PTPN6. [The UniProt Consortium]
