Human LAIR2 Antibody

LAIR-2 (leukocyte-associated Ig-like receptor-2; CD306) is a secreted, 131 amino acid (aa) protein that contains one Ig-like C2 type domain, making it a member of the Ig superfamily. When compared to LAIR-1, its transmembrane counterpart, it shares 83% aa identity across the signal sequence and extracellular domains; (1‑3) although one is secreted and one is membrane-bound, the two LAIR proteins are thought to have arisen from a common gene ancestor and appear to share similar adhesion profiles. This suggests that LAIR-2 may compete with LAIR-1 for ligand binding (3, 4). A 114 aa alternate splice form of LAIR-2 is truncated at the C‑terminus, but retains the entire Ig domain (1‑3). The expression profile of these splice forms, and the presence of orthologs in other species, have not been reported.
