Background: VSIG2

V-set and immunoglobulin domain-containing protein 2 (VSIG2), also known as cortical thymocyte-like protein (CT-like protein), is a member of the immunoglobulin superfamily (Igsf) that was originally described in Xenopus and was referred to as cortical thymocyte marker in Xenopus, or CTX. The clone isolated from the human genomic library was called CTH (1). Mature human VSIG2 is a single-pass type I transmembrane protein with a 220 amino acid (aa) extracellular domain (ECD) that contains one C2-type and one V-type immunoglobulin-like domains, and a 63 aa cytoplasmic region linked to the ECD by a short 21 aa transmembrane domain. Human VSIG2 ECD shares 85% and 86% aa sequence identity with mouse and rat VSIG2, respectively. VSIG2 is structurally related to the B7 family of immune regulatory proteins. Our studies at R&D Systems show that VSIG2 inhibits T cell activation, including IL17 and interferon gamma production.
