Background: CD300a/LMIR1

CD300a, also known as LMIR1, CMRF-35H, IRp60, CLM-8, and MAIR-I, is a 60 kDa glycoprotein member of the immunoglobulin superfamily (1). Mouse CD300a consists of a 158 amino acid (aa) extracellular domain (ECD) with one Ig-like V-type domain, a 21 aa transmembrane segment, and a 112 aa cytoplasmic domain that contains three immunoreceptor tyrosine-based inhibitory motifs (ITIMs) and a non-canonical ITIM (2, 3). Within the ECD, mouse CD300a shares 40% and 66% aa sequence identity with human and rat CD300a, respectively. Alternate splicing generates an additional mouse CD300a isoform with a 4 aa deletion following the Ig-like domain (3). In mouse, CD300a is expressed on peripheral eosinophils, mast cells, neutrophils, dendritic cells, macrophages, and some B cells (2‑4). Antibody cross‑linking of CD300a induces phosphorylation of tyrosine residues in the cytoplasmic domain. This leads to the recruitment of phosphatases SHIP, SHP-1, and SHP-2 and inhibition of NK cell, eosinophil, and mast cell activation (2, 3, 5‑7). Cross‑linking of CD300a to other surface proteins such as SCF R or Fc epsilon RI on mast cells, Fc gamma RIIA on neutrophils, or CCR3 on mast cells and eosinophils inhibits downstream signaling from those receptors (4, 8‑10). CD300a cross‑linking also limits the in vivo activities of these cells with a subsequent reduction of allergic inflammation symptoms (4, 7, 9).
