Background: VSTM2B

VSTM2B, or V-set and transmembrane domain-containing protein 2B is a membrane protein which includes a 235 amino acid (aa) extracellular domain that contains an Ig-like V-type domain, a 21 aa transmembrane domain, and one aa in cytoplasm. This extracellular domain shares 45% aa identity human VSTM2A. The mature extracellular domain of human VSTM2B shares 86% and 85% aa sequence identity for the mouse and rat homolog, respectively. Currently, both the expression pattern and biological functions of VSTM2B remain unknown. our in house data show that VSTM2B inhibits the human T cell activation, including anti-CD3 induced IL-2, IFN-gamma secretion, and T cell proliferation.
