Function

Interferon (IFN)-inducible GTPase that plays important roles in innate immunity against a diverse range of bacterial, viral and protozoan pathogens (PubMed:16511497, PubMed:22106366, PubMed:29144452, PubMed:31268602, PubMed:32510692, PubMed:32581219, PubMed:37797010, PubMed:7512561). Hydrolyzes GTP to GMP in two consecutive cleavage reactions: GTP is first hydrolyzed to GDP and then to GMP in a processive manner (PubMed:16511497, PubMed:32510692, PubMed:7512561). Following infection, recruited to the pathogen-containing vacuoles or vacuole-escaped bacteria and promotes both inflammasome assembly and autophagy (PubMed:29144452, PubMed:31268602). Acts as a positive regulator of inflammasome assembly by facilitating the detection of inflammasome ligands from pathogens (PubMed:31268602, PubMed:32510692, PubMed:32581219). Involved in the lysis of pathogen-containing vacuoles, releasing pathogens into the cytosol (By similarity). Following pathogen release in the cytosol, forms a protein coat in a GTPase-dependent manner that encapsulates pathogens and promotes the detection of ligands by pattern recognition receptors (PubMed:32510692, PubMed:32581219). Plays a key role in inflammasome assembly in response to infection by Gram-negative bacteria: following pathogen release in the cytosol, forms a protein coat that encapsulates Gram-negative bacteria and directly binds to lipopolysaccharide (LPS), disrupting the O-antigen barrier and unmasking lipid A that is that detected by the non-canonical inflammasome effector CASP4/CASP11 (PubMed:32510692, PubMed:32581219). Also promotes recruitment of proteins that mediate bacterial cytolysis, leading to release double-stranded DNA (dsDNA) that activates the AIM2 inflammasome (PubMed:31268602). Involved in autophagy by regulating bacteriolytic peptide generation via its interaction with ubiquitin-binding protein SQSTM1, which delivers monoubiquitinated proteins to autolysosomes for the generation of bacteriolytic peptides (By similarity). Confers protection to several pathogens, including the bacterial pathogens L.monocytogenes and M.bovis BCG as well as the protozoan pathogen T.gondii (PubMed:31268602). Exhibits antiviral activity against influenza virus (PubMed:22106366).

Activity summary

The target known commonly as GBP1 or guanylate-binding protein 1 plays a mechanical role as a large GTPase with a molecular mass of approximately 67 kDa. This protein is expressed in various tissues most notably in interferon-gamma-induced human cells. GBP1 localizes mainly in the cytoplasm and associates with cellular membranes. Alternate designations for the GBP1 protein include GBP 1. Its role as a GTPase involves hydrolyzing GTP which is critical for its cellular functions.

Biological function summary

The GBP1 protein supports cellular defense mechanisms against pathogens such as viruses and bacteria. GBP1 participates in the hydrolysis of GTP to GMP an action that influences its anti-pathogenic effects. It is a member of the interferon-inducible large GTPase family and can form oligomeric complexes enhancing its antiviral and antimicrobial activity. It interacts with various proteins linked to innate immunity and contributes to modulating the immune response.

Pathways

GBP1 is involved in pathways linked to interferon signaling and innate immunity. The protein plays a significant role in the JAK-STAT signaling pathway where it exerts its antiviral effects. GBP1 interacts closely with other proteins such as STAT1 and is responsive to interferon signals influencing gene expression and immune responses. Its activity in these pathways is critical for mounting an effective defense against infections.

Associated diseases and disorders

GBP1 has been associated with inflammatory diseases and cancer. The protein's expression levels often increase in response to inflammatory signals implicating it in the pathogenesis of diseases like Crohn's disease. Moreover GBP1 has a connection with cancer-related mechanisms where it might affect tumor cell proliferation. In these contexts proteins such as STAT1 and other interferon-responsive proteins relate closely to the function and regulatory mechanisms of GBP1.
