Product Summary for Human Siglec-10 Antibody


Mouse myeloma cell line NS0-derived recombinant human Siglec-10
Accession # Q96LC7


Detects human Siglec-10 in direct ELISAs and Western blots. In direct ELISAs, 100% cross-reactivity with recombinant human (rh) Siglec-11 is observed. In Western blots (reducing conditions), approximately 25% with rhSiglec-11 is observed. In direct ELISAs and Western blots, no cross-reactivity with rhSiglec-2, -3, -5, -7, -9, or recombinant mouse Siglec-F is observed.

Background: Siglec-10

Siglecs (sialic acid binding Ig-like lectins) are I-type lectins that belong to the immunoglobulin superfamily. They are characterized by an N‑terminal Ig-like V-type domain which mediates sialic acid binding, followed by a varying number of Ig-like C2-type domains. Siglecs 5‑11 constitute the CD33/Siglec-3 related group, and are differentially expressed in the hematopoietic system (1‑3). Siglec-G is the apparent ortholog of human Siglec-10 (4). The human Siglec-10 cDNA encodes a 697 amino acid (aa) precursor that includes a 16 aa signal sequence, a 534 aa extracellular domain (ECD), a 21 aa transmembrane segment, and a 126 aa cytoplasmic domain. The ECD contains one Ig-like V-type domain and four Ig-like C2-type domains, while the cytoplasmic domain contains two immunoreceptor tyrosine-based inhibitory motifs (ITIM) (5‑8). Five splice variants of human Siglec-10 differ in their deletions within the ECD. A potentially secreted sixth variant contains the Ig-like V-type domain followed by a 45 aa substitution (5‑7, 9). Within the ECD, human Siglec-10 is most closely related to Siglec-5 (42% aa sequence identity). It shares 63% aa sequence identity with mouse Siglec-G. Siglec-10 is expressed on eosinophils, neutrophils, monocytes, and B cells (5, 8) with some splice variants predominating in particular cell types and tissue locations (6, 7, 9). It is up‑regulated on eosinophils in mouse models of allergic respiratory inflammation (10). Siglec‑10 binds sialated proteins and lipids in alpha2,3 or alpha2,6 linkage and shows a preference for GT1b gangliosides (7, 11). This binding can be modulated by cis interactions of Siglec-10 with sialated molecules expressed on the same cell (7). When tyrosine phosphorylated, the cytoplasmic ITIMs interact with phosphatases SHP-1 and SHP‑2 to propagate inhibitory signals (5, 9).
