This data was developed using ab179829, the same antibody clone in a different buffer formulation.

Lanes 1-4 : Merged signal (red and green). Green - ab179829 observed at 67 kDa. Red - loading control ab8245 observed at 36 kDa.

ab179829 Anti-GBP2 antibody [EPR13206] - N-terminal was shown to specifically react with GBP2 in wild-type A549 cells. Loss of signal was observed when knockout cell line ab267218 (knockout cell lysate ab257962) was used. Wild-type and GBP2 knockout samples were subjected to SDS-PAGE. ab179829 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) were incubated overnight at 4°C at 1 in 1000 dilution and 1 in 20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1 in 20000 dilution for 1 hour at room temperature before imaging.

Supplementary information

GBP2 also known as Guanylate Binding Protein 2 is a member of the dynamin superfamily of large GTPases. It has an approximate mass of 67 kDa. This protein finds expression predominantly in macrophages and other immune cells. The involvement of GBP2 in cellular defense mechanisms reflects its upregulation by interferon-gamma where it takes part in immune responses against microbial and viral infections.
Biological function summary

Guanylate Binding Protein 2 participates in immune response regulation. It does not function as part of a large multiprotein complex but acts primarily as a monomer. GBP2 disrupts pathogenic molecular machinery by binding to microbial enzymes leading to their inhibition which limits pathogen survival. This mechanism ensures that GBP2 remains a significant factor in the cell's intrinsic ability to fight infections at the molecular level.

Pathways

Guanylate Binding Protein 2 plays an important role in the interferon-induced defense pathways. It participates in the immune effector pathways primarily connecting to processes like the JAK-STAT signaling pathway. Through this involvement GBP2 helps enhance the expression of a variety of immunologically relevant genes. Additionally GBP2 often interacts with other members of the GBP family including GBP1 and GBP5 to amplify immune responses and signaling cascades.

Guanylate Binding Protein 2 shows a significant connection to infectious diseases like tuberculosis and viral infections such as hepatitis C. Overexpression or dysregulation of GBP2 can influence the progression and severity of these conditions. Additionally GBP2's interaction with proteins involved in inflammatory responses such as other interferon-induced proteins highlights its influence over auto-inflammatory conditions and its potential as a biomarker for disease progression.

Target data

Interferon (IFN)-inducible GTPase that plays important roles in innate immunity against a diverse range of bacterial, viral and protozoan pathogens (PubMed : 31091448). Hydrolyzes GTP to GMP in 2 consecutive cleavage reactions, but the major reaction product is GDP (PubMed : 8706832). Following infection, recruited to the pathogen-containing vacuoles or vacuole-escaped bacteria and acts as a positive regulator of inflammasome assembly by promoting the release of inflammasome ligands from bacteria (By similarity). Acts by promoting lysis of pathogen-containing vacuoles, releasing pathogens into the cytosol (By similarity). Following pathogen release in the cytosol, promotes recruitment of proteins that mediate bacterial cytolysis : this liberates ligands that are detected by inflammasomes, such as lipopolysaccharide (LPS) that activates the non-canonical CASP4/CASP11 inflammasome or double-stranded DNA (dsDNA) that activates the AIM2 inflammasome (By similarity). Confers protection to the protozoan pathogen Toxoplasma gondii (By similarity). Independently of its GTPase activity, acts as an inhibitor of various viruses infectivity, such as HIV-1, Zika and influenza A viruses, by inhibiting FURIN-mediated maturation of viral envelope proteins (PubMed : 31091448).
