Detection of Siglec-G in Mouse Splenocytes by Flow Cytometry. Mouse splenocytes were stained with Rat Anti-Mouse Integrin alpha M/CD11b PE‑conjugated Monoclonal Antibody (Catalog # FAB1124P) and either (A) Rat Anti-Mouse Siglec-G APC‑conjugated Monoclonal Antibody (Catalog # FAB7775A) or (B) Rat IgG2A Allophycocyanin Isotype Control (Catalog # IC006A).

Siglecs (sialic acid binding Ig-like lectins) are I-type lectins that belong to the immunoglobulin superfamily. They are characterized by a V-type Ig-like domain which mediates sialic acid binding, followed by varying numbers of C2-type Ig-like domains. Mouse Siglec-G, the apparent ortholog of human Siglec-10, is a 110-120 kDa, 688 amino acid (aa) type I transmembrane protein mainly expressed on mouse B1-type B cells. It controls B1 cell survival, selection, expansion and calcium signaling by negatively regulating B cell receptor signals. A potentially secreted 269 aa variant diverges after the first two Ig-like domains. Mouse Siglec-G shares approximately 63% aa sequence identity with human Siglec-10 within the extracellular domain.
