Background: VSIG3

VSIG3 (V-­set and immunoglobulin domain containing 3) also known as IgSF11 (Immunoglobulin superfamily member 11), is an approximately 50 kDa type I transmembrane adhesion protein of the Ig superfamily. Mature mouse VSIG3 consists of a 218 amino acid (aa) extracellular domain (ECD) containing one V-type Ig-like domain and one Ig-like C2-type domain, a 21 aa transmembrane domain, and a 167 aa cytoplasmic domain. Within the ECD, mouse VSIG3 shares 95% and 98% aa identity with human and rat VSIG3, respectively. VSIG3 is expressed on epithelial and endothelial cells, neurons and glial cells, and platelets (1). It localizes to epithelial tight junctions and mediates homophilic in trans cell adhesion (1-3). VSIG3 also localizes to neuronal postsynaptic densities where it recruits the GluA1 and GluA2 subunits of AMPA receptors and supports excitatory synaptic transmission (4). In zebrafish, VSIG3 is expressed in melanophores and their precursors and plays a role in the development and patterning of pigment cells (5). VSIG-3 expression is elevated in colorectal cancers and hepatocellular carcinomas as well as
intestinal-type gastric cancers. Suppression of VSIG-3 by siRNA retarded the growth of gastric cancer cells, suggesting that VSIG-3 is a good candidate for gastric cancer immunotherapy (6).
