Siglec-11 is a 686 amino acid single-pass type I membrane protein that contains one Ig-like V-type domain and three Ig-like C2-type domains. In humans, Siglec-11 is widely expressed on tissue macrophages, which include microglia in the brain. No expression of Siglec-11 is seen in the brain compartment of non-human primates. Siglec-11 functions as an adhesion molecule that preferentially binds to α-2, 8-linked sialic acid trimers and mediates sialic acid binding to cells. It is a negative regulator of microglia, both related to inflammation and phagocytic function. In murine microglial cells with ectopic expression of human Siglec-11, stimulation of Siglec-11 could induce the transcription of the pro-inflammatory mediator genes, such as IL-1β and nitric oxide synthase-2. Phagocytosis of apoptotic neuronal material has shown to be reduced in Siglec-11 expressing microglia. Co-culture of Siglec-11 expressing microglia and neurons demonstrated neuroprotective functions of Siglec-11.

Antigen Details
- Structure
- 698 amino acids, predicted molecular weight of 66 kD. Apparent molecular weight is 100-130 kD due to N-glycosylation.
- Distribution
-
Plasma membrane.
- Function
- Adhesion molecule that mediates sialic-acid dependent binding to cells. The cytosolic domain of Siglec-11 is phosphorylated at tyrosine residue(s) upon pervanadate treatment of cells and then it recruits the protein-tyroisine phosphatases SHP-1 and SHP-2. Such interaction induces inhibitory cellular signals in immune response.
- Interaction
- Interacts with PTPN6/SHP-1 and PTPN11/SHIP-2 upon phosphorylation.
- Ligand/Receptor
- α-2,8-linked sialic acid trimers.
