Western blot analysis of wild type mouse spleen (lane 1) and Siglec-E knock out mouse spleen (lane 2) using anti-Siglec E antibody (clone M1307D09) under non-reducing conditions. Anti-β actin antibody (clone poly6221) was used as a loading control. Siglec-E knock out mouse spleen tissue was kindly provided by Dr. Ajit Varki, UCSD.

Siglecs (sialic acid binding Ig-like lectins) are type I membrane proteins with an extracellular region containing a sialic acid binding V-set Ig-like domain at the N-terminus, followed by varying numbers of C2-set Ig domains. The cytoplasmic tails of all siglecs have tyrosine based motifs with signaling functions. Siglecs are widely expressed on hematopoietic cells, often in a cell-type-specific manner. Their ligands, sialic acids, are negatively charged monosaccharides found on cell-surface glycoproteins and glycolipids. Studies suggest that siglecs may participate in cell-cell interactions or act as receptors for the entry of viral or bacterial pathogens. Additionally, the presence of immunoreceptor tyrosine-based inhibitory motifs (ITIMs) in their cytoplasmic domain indicates that these molecules may play a role in the suppression of immunoreceptor signaling. Siglec-E is a mouse CD33-related siglec that selectively regulates early recruitment of neutrophils to the lungs in an acute lung inflammation induced by lipopolysaccharides. Siglec E-deficient mice exhibited exaggerated neutrophil recruitment that is reversible by using a blockade of the β2 integrin, CD11b. In addition, sialidase treatment of fibrinogen reverses the suppressive effects of Siglec-E on CD11b signaling. This suggests that sialic acid recognition by Siglec-E is required for its inhibitory function. These findings indicate that Siglec-E is an important negative regulator of neutrophil recruitment to the lung and β2 integrin-dependent signaling.

Antigen Details
- Structure
- 569 amino acids with a predicted molecular weight of approximately 65 kD.
- Distribution
-
Murine Siglec-E is expressed by neutrophils, natural killer (NK) cells, monocytes, macrophages, dendritic cells, and B1 cells.
- Function
- Siglec-E regulates neutrophil recruitment. Siglec-E signaling negatively regulates the LPS-induced production of TNF-α and IL-6 by macrophages. It is upregulated by a variety of TLR agonists.
