- Sujet
- Siglec proteins (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. In the cytosolic domain, most Siglecs contain a combination of tyrosine motifs, including immunoreceptor tyrosine-based inhibitory motifs (ITIM), along with ITIM-like, Grb2-binding, and Fyn kinase sites. 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 and act as receptors for the entry of viral or bacterial pathogens. In addition, the presence of ITIM indicates that these molecules play a role in the suppression of immunoreceptor signaling. Siglecs can be classified into two subgroups with Siglec 1, 2, and 4, as one group and a Siglec 3/CD33-related subgroup (Siglec 3 and 5 through 14) as the second. Siglec 3, also known as CD33 and GP67, is mainly expressed on myeloid cells and also on activated NK and T cells. Human Siglec 3 has two tyrosine residues in its cytoplasmic domain. When phosphorylated, these tyrosines could confer an inhibitory function. CD33 polymorphism has been associated with late-onset Alzheimer's disease.
