HEK293 human embryonic kidney cell line transfected with (A) Human VSIG3 or (B) irrelevant protein, and EGFP, was stained with Mouse Anti-Human VSIG3 Monoclonal Antibody (Catalog # MAB92292) followed by anti-Mouse IgG APC-conjugated secondary antibody (Catalog # F0101B). Quadrant markers were set based on Mouse IgG1 Isotype Control (Catalog # MAB002, data not shown). View our protocol for Staining Membrane-associated Proteins.

Background: VSIG3

VSIG3 (V-set and Ig domain-containing protein 3; also BT-IgSF and IGSF11) is a 52 kDa brain and testis-specific protein that belongs to the IGSF11 family of proteins. It is expressed by neurons, astrocytes and oligodendroglia. VSIG3 is an adhesion molecule that forms Ca-independent homophilic interactions in trans. Human VSIG3 is 413 amino acids (aa) in length. It is a type I transmembrane glycoprotein that contains a 219 aa extracellular domain (ECD). The ECD contains one V-type (aa 23‑136) and one C2-type Ig-like domain (aa 144‑234). Over aa 23‑245, human VSIG3 is 94% aa identical to mouse VSIG3. Two potential splice variants exist in human. Both exhibit a 16 aa substitution for the first 17 aa of the signal sequence, and one contains an additional single Ala substitution for aa 211‑235.
