LILRB1
(Leukocyte Immunoglobulin-Like Receptor, Subfamily B (With TM and ITIM Domains), Member 1 (LILRB1))
LILRB1, also known as CD85j and IL-T2, is a 110 kDa transmembrane glycoprotein in the LILR immunoregulatory protein family. Mature human LILRB1 consists of a 438 amino acid (aa) extracellular domain (ECD) with 4 tandem Ig-like domains, a 21 aa transmembrane segment, and a 168 aa cytoplasmic domain with 4 inhibitory ITIM motifs.LILRB1 is a receptor for class I MHC antigens.
Poids moléculaire
23.1 kDa. Due to glycosylation, the protein migrates to 25-30 kDa based on Tris-Bis PAGE result.
