Anti-GBP3

This gene encodes a member of the guanylate-binding protein (GBP) family. GBPs specifically bind guanine nucleotides (GMP, GDP, and GTP) and contain two of the three consensus motifs found in typical GTP-binding proteins. The encoded protein interacts with a member of the germinal center kinase family. Multiple transcript variants encoding different isoforms have been been found for this gene. [provided by RefSeq, Jan 2016], Protein function: Interferon (IFN)-inducible GTPase that plays important roles in innate immunity against a diverse range of bacterial, viral and protozoan pathogens (PubMed:22106366). Hydrolyzes GTP very efficiently, GDP rather than GMP is the major reaction product. 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. Acts by promoting lysis of pathogen- containing vacuoles, releasing pathogens into the cytosol. 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. Exhibits antiviral activity against influenza virus (PubMed:22106366). [The UniProt Consortium] Recommended dilutions: Western Blot: 1/500 - 1/2000. Immunohistochemistry: 1/100 - 1/300.
