Siglec-3/CD33, Mouse (HEK293, Fc)

Siglec-3/CD33, a sialic-acid-binding lectin, crucially mediates cell-cell interactions and immune cell quiescence. Preferring sialic acid on specific mucins, it forms homodimers, interacting with PTPN6/SHP-1 and PTPN11/SHP-2 upon phosphorylation. CD33 also engages C1QA through its C-terminus, activating CD33 inhibitory motifs. Siglec-3/CD33 Protein, Mouse (HEK293, Fc) is the recombinant mouse-derived Siglec-3/CD33 protein, expressed by HEK293 , with C-hFc labeled tag.
