Figure 1: Human guanylate-binding protein 1 (GBP1) is detected by immunoblotting using anti-GBP1 (human), pAb (IN111) (Prod. No. AG-25B-6001).
Method: GBP1 is analyzed by Western blot in cell extracts of HeLa cells treated overnight with 0, 10 or 100 ng/ml of IFN-γ (human) (rec.) (His) (Prod. No. CHI-HR-200IFNG). Cell extracts (20µl) are separated by SDS-PAGE under reducing conditions, transferred to nitrocellulose and incubated with anti-GBP1 (human), pAb (IN111) (2µg/ml). Proteins are visualized by TMB.

Description
Guanylate-binding proteins (GBPs) are a family of antimicrobial proteins that are expressed by host cells in response to pathogens. Expression of GBPs is induced by both type I IFNs and IFN-γ. During infection with pathogen (S. Typhimurium or Salmonella), GBP1 binds first to surface of the bacteria, leading to the recruitment of GBP2, GBP3 and GBP4. GBP1 binds to the component LPS (Lipopolysaccharide) of the bacteria as a first step bringing caspase-4 to the surface of bacteria, leading to caspase-1 activation, Gasdermin D cleavage and finally pyroptotic cell death. GBP1 is cleaved and inactivated by Caspase-1. GBP1 also promotes Toxoplasma DNA detection by AIM2-ASC-Caspase-8 leading to apoptosis. GBP1 acts as a gatekeeper of cell death pathways, which respond specifically to infecting microbes.
