Target Background

ATP- and magnesium-dependent helicase that plays an essential role in innate immunity. Participates in the DNA-triggered cGAS/STING pathway by promoting the DNA binding and activation of CGAS. Enhances also DDX58-induced type I interferon production probably by helping DDX58 at sensing pathogenic RNA. In addition, plays an essential role in stress granule formation. Unwinds preferentially partial DNA and RNA duplexes having a 17 bp annealed portion and either a hanging 3' tail or hanging tails at both 5'- and 3'-ends. Unwinds DNA/DNA, RNA/DNA, and RNA/RNA substrates with comparable efficiency. Acts unidirectionally by moving in the 5' to 3' direction along the bound single-stranded DNA. Phosphorylation-dependent sequence-specific endoribonuclease in vitro. Cleaves exclusively between cytosine and adenine and cleaves MYC mRNA preferentially at the 3'-UTR.
Gene References into Functions
  1. The disruption of stress granules (SGs) during the late stage of Enterovirus 71 (EV71) infection is caused by viral protease 3C-mediated cleavage of G3BP stress granule assembly factor 1 (G3BP1). Over-expression of G3BP1-SGs negatively impacts viral replication at the cytopathic effect (CPE), protein, RNA, and viral titer levels. PMID: 30006004
  2. JMJD6 is a novel Stress Granule component that interacts with G3BP1 complexes, and its expression reduces G3BP1 monomethylation and asymmetric dimethylation at three Arg residues. PMID: 28972166
  3. Activated glucocorticoid receptor induced phosphorylation of v-AKT Murine Thymoma Viral Oncogene Homologue (AKT) kinase, which in turn phosphorylated and promoted nuclear translocation of G3BP1.

  4. Results show the crystal structure of the NTF2-like domain of G3BP-1 in complex with nsP3 protein revealing a poly-complex of G3BP-1 dimers interconnected through the FGDF motifs in nsP3. Although in vitro and in vivo binding studies revealed a hierarchical interaction of the two FGDF motifs with G3BP-1, viral growth curves clearly demonstrated that two intact FGDF motifs are required for efficient viral replication.
