Siglec-15 Protein, Mouse (Biotinylated, HEK293, His)

Siglec-15 Protein, a Siglec family member and type-1 transmembrane protein, is constitutively expressed in osteoclasts, macrophages and dendritic cells. Siglec-15 plays a pivotal role in the development and differentiation of osteoclastogenesis, inhibiting antigen-specific T cell responses in vitro and in vivo. Siglec-15 Protein, Mouse (Biotinylated, HEK293, His) is the recombinant mouse-derived Siglec-15 protein, expressed by HEK293 , with C-His labeled tag. The total length of Siglec-15 Protein, Mouse (Biotinylated, HEK293, His) is 239 a.a., with molecular weight of 35-43 kDa.

Siglec-15, a Siglec family member and type-1 transmembrane protein, is constitutively expressed in osteoclasts, macrophages and dendritic cells. Siglec-15 acts upstream of or within regulation of actin cytoskeleton organization. Siglec-15 deficiency can promote bone formation and reduce bone resorption, indicating that Siglec-15 plays a pivotal role in the development and differentiation of osteoclastogenesis and may serve as a target to inhibit bone resorption and promote bone remodeling that increases bone mass. Siglec-15 is a predominantly macrophage-mediated suppressor of T cell responses. In tumors, Siglec-15 is negatively regulated by IFN-γ, thus influencing effector T cell-mediated antitumor immunity. Genetic ablation or antibody blockade of Siglec-15 amplifies anti-tumor immunity in the TME and inhibits tumor growth in some mouse models.
