Sialic acid binding Ig-like lectin 8

Sialic acid-binding immunoglobulin (Ig)-like lectins, or SIGLECs (e.g., CD33 (MIM 159590)), are a family of type 1 transmembrane proteins each having a unique expression pattern, mostly in hemopoietic cells. SIGLEC8 is a member of the CD33-like subgroup of SIGLECs, which are localized to 19q13.3-q13.4 and have 2 conserved cytoplasmic tyrosine-based motifs: an immunoreceptor tyrosine-based inhibitory motif, or ITIM (see MIM 604964), and a motif homologous to one identified in signaling lymphocyte activation molecule (SLAM; MIM 603492) that mediates an association with SLAM-associated protein (SAP; MIM 300490) (summarized by Foussias et al., 2000 [PubMed 11095983]).[supplied by OMIM, May 2010] (from NCBI)

Bochner et al., Baltimore, United States. In Cytokine, 2012
Eosinophils primed by IL-33 and/or IL-5 in vivo would be expected to display enhanced susceptibility to undergoing Siglec-8-induced apoptosis.

expressed on eosinophils and basophils from subjects with chronic eosinophilic leukemia, chronic myelogenous leukemia, and on malignant and non-malignant bone marrow mast cells
Polymorphisms in the sialic acid-binding immunoglobulin-like lectin-8 (Siglec-8) gene are associated with susceptibility to asthma.
Bochner et al., Baltimore, United States. In Eur J Hum Genet, 2010
The Siglec-8 gene may be a susceptibility locus for asthma.
Mast cells: makers and breakers of allergic inflammation.
Maurer et al., Berlin, Germany. In Curr Opin Allergy Clin Immunol, 2009
For example, the newly discovered siglec-8 receptor might act as an inhibitor of mast cell degranulation and thus of mast cell-mediated allergic inflammation.
Eosinophil-selective binding and proapoptotic effect in vitro of a synthetic Siglec-8 ligand, polymeric 6'-sulfated sialyl Lewis x.
Bochner et al., Baltimore, United States. In J Pharmacol Exp Ther, 2009
Selective and specific engagement and binding of Siglec-8 on eosinophils by a synthetic 6'-sulfo-sLe(x)-containing ligand could be useful for controlling eosinophilic inflammatory responses in vivo.
Interleukin-5 priming of human eosinophils alters siglec-8 mediated apoptosis pathways.
Bochner et al., Baltimore, United States. In Am J Respir Cell Mol Biol, 2008
IL-5 priming enhances Siglec-8-mediated mitochondrial and ROS-dependent eosinophil apoptosis and eliminates caspase dependence.
Probing sialic acid binding Ig-like lectins (siglecs) with sulfated oligosaccharides.
Bovin et al., Moscow, Russia. In Biochemistry (mosc), 2006
It was shown that sulfate derivatives of LacNAc did not bind siglecs-1, -4, -5, -6, -7, -8, -9, and -10; binding of 6'-O-Su-LacNAc to siglec-8 was stronger than binding of 3'SiaLacNAc.

Camilleri et al., Oxford, United Kingdom. In Eur J Biochem, 2001
In addition to the previously characterized siglecs, sialoadhesin, CD22, CD33 and myelin-associated glycoprotein, several new ones, siglec-5, siglec-7 and siglec-8, have recently been cloned.
Molecular characterization of a Siglec8 variant containing cytoplasmic tyrosine-based motifs, and mapping of the Siglec8 gene.
Diamandis et al., Toronto, Canada. In Biochem Biophys Res Commun, 2000
Further, we have identified a novel Siglec8 variant, named Siglec8-Long (Siglec8-L), which differs in its last two exons from the previously published mRNA sequence of Siglec8 (GenBank Accession No. AF195092).
Identification and molecular characterization of a novel member of the siglec family (SIGLEC9).
Diamandis et al., Toronto, Canada. In Genomics, 2000
This novel siglec shows a high degree of homology to many members of the siglec family, including siglec-7 (80%), siglec-8 (72%), siglec-5 (65%), and CD33 (64%).
