Detection of Human VSIG2 by Western Blot. Western blot shows lysates of human prostate tissue. PVDF membrane was probed with 2 µg/mL of Mouse Anti-Human VSIG2 Monoclonal Antibody (Catalog # MAB5177) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for VSIG2 at approximately 45 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

VSIG2 (V-set and Ig domain-containing protein 2; also CTM and CT-like protein) is presumably a 50‑60 kDa member of the CTX family of proteins. It shows expression in stomach and prostate by Northern blot, and likely participates in cell adhesion. Human VSIG2 precursor is 327 amino acids (aa) in length. It is a type I transmembrane (glyco)protein that contains a 220 aa extracellular domain (ECD) (aa 24‑243) and a 63 aa cytoplasmic region. The ECD contains one V-type (aa 24‑137) and one C2-type Ig-like domain (aa 144‑233). One potential splice variant exists that shows a deletion of aa 285‑327. Over aa 24‑243, human VSIG2 is 85% aa identical to mouse VSIG2.
