Recombinant Human Leukocyte Ig-Like Receptor B2/LILRB2/ILT4/CD85d (C-Avi-6His) Biotinylated

Product Specifications

Background

Members of the immunoglobulin-like transcript (ILT) family are activating and inhibitory immunoreceptors whose genes are located same locus that encodes killer cell Ig-like receptors (KIR) . Leukocyte Immunoglobulin-Like Receptor Subfamily B Member 2 (LIR-2) is a type I transmembrane protein. LIR-2 is expressed primarily on monocytes and dendritic cells (DC) . Human LIR-2 is produced as a 598 amino acino acid precursor including a 21 aa signal sequence, a 440 aa extracellular domain (ECD), a 21 aa transmenbrane segment, and a 116 aa cytoplasmic domain. LIR-2 binds to Classical MHCI proteins. Ligation of LIR-2 incluces Tyr phosphorylation within its cytoplasmic ITIMs, a requirement for association with SHP-1. LIR-2 mediates tolerogenic DC-induced CD4+ T cell energy in vitro and in vivo.
