Siglec-3/CD33 Protein, Mouse (HEK293, Fc)
Based on 1 Customer Validation
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.
- Species: Mouse
- Source: HEK293

Description

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.

Background
Siglec-3/CD33, a sialic-acid-binding immunoglobulin-like lectin, plays a crucial role in mediating cell-cell interactions and maintaining immune cells in a resting state. It exhibits a preference for binding sialic acid on the short O-linked glycans of specific mucins. The protein forms homodimers through disulfide linkages and interacts with signaling molecules such as PTPN6/SHP-1 and PTPN11/SHP-2 upon phosphorylation. Additionally, CD33 engages with C1QA via its C-terminus, leading to the activation of CD33 inhibitory motifs.
