Sialic acid-binding Ig-like lectin 8 is a protein that in humans is encoded by the SIGLEC8 gene. This gene is located on chromosome 19q13.4, about 330 kb downstream of the SIGLEC9 gene. Within the siglec family of transmembrane proteins, Siglec-8 belongs to the CD33-related siglec subfamily, a … See more Siglec-8 was first identified by CD33 homology screening of ESTs from a cDNA library generated from a patient diagnosed with idiopathic hypereosinophilic syndrome and was originally termed SAF-2 (sialoadhesin family … See more Siglec-8 is expressed by human eosinophils, mast cells, and, to a lesser extent, basophils. It has thus garnered attention as a molecule that is uniquely expressed by immune effector cells involved in asthma and allergy. In both eosinophils and … See more Eosinophils Consistent with the role of most siglecs and the presence of the intracellular ITIM, Siglec-8 has been found to function as an inhibitory immunoregulatory receptor. Ligation of Siglec-8 induces cell death in eosinophils, and, … See more In a randomized clinical trial, lirentelimab, a monoclonal antibody targeting SIGLEC8 has been evaluated as a treatment for eosinophilic gastritis and duodenitis. See more Two splice variants of Siglec-8 exist. The initially characterized form contains 431 amino acid residues in total, 47 of which comprise an uncharacteristically short cytoplasmic tail … See more Potential glycan ligands for Siglec-8 have been screened by glycan array. The glycan NeuAcα2–3(6-O-sulfo)Galβ1–4[Fucα1–3]GlcNAc, also known as 6′-sulfo-sialyl Lewis X, binds with high affinity to both Siglec-8 and to a mouse siglec, Siglec … See more CD33-related siglec subfamily Due to its high level of sequence homology with CD33 (Siglec-3), Siglec-8 is grouped within the CD33-related siglec subfamily. This family is composed of a rapidly evolving group of siglecs that share 50–99% sequence … See more WebSep 1, 2024 · 2.1. Sialic acid binding by Siglecs. In general, it seems that one salt bridge, mediated by an arginine residue, is particularly important for the interactions (Supplement 1A).Regarding human Siglec-1 (hSiglec-1), it is known that the sialic acid binding domain is located at the N-terminus of the protein (May et al., 1998).The guanidine group of R116 of … ravinia beatles exhibit
