VSIG1 Antibody

Western blot shows lysates of rat testis tissue. PVDF membrane was probed with 1 µg/mL of Goat Anti-Mouse/Rat VSIG1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5324) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). Specific bands were detected for VSIG1 at approximately 55 and 70 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.

Background

VSIG1 (V-set and Ig domain-containing protein 1; also Glycoprotein 34 and Cell surface antigen 33) is a 55‑70 kDa member of the JAM family of Ig-Superfamily proteins. It shows expression on gastric epithelium and testicular germ cells and likely participates in cell adhesion. Mouse VSIG1 precursor is 407 amino acids (aa) in length. It is a type I transmembrane glycoprotein that contains a 211 aa extracellular domain (ECD) (aa 23‑234) and a 152 aa cytoplasmic region. The ECD contains one V-type (aa 23‑134) and one C2-type Ig-like domain (aa 145‑229). Over aa 23‑234, mouse VSIG1 is 94% and 81% aa identical to rat and human VSIG1, respectively. There is one potential alternate start site at Met108.
