Background: PILR-beta

Paired immunoglobulin-like, type 2 receptor beta (PILR-beta ) is a type I transmembrane (TM) glycoprotein belonging to the Ig superfamily. It is the activating counterpart to the ITIM-bearing PILR-alpha inhibitory receptor. PILR-beta is expressed in a wide variety of tissues including hematopoietic cells. Mature human PILR-beta is a 208 amino acid (aa) protein with one V-type Ig-like extracellular domain, a truncated cytoplasmic tail, and positively-charged residues in its TM domain that interacts with ITAM‑bearing adaptor molecules. Within the V-type Ig-like region in their ECD, human PILR-beta and PILR-alpha share a 92% aa sequence identity. The aa sequence of mouse PILR-beta ECD is only 43% identical to that of the human protein.
