'''Ras GTPase-activating protein-binding protein 1''' is an [[enzyme]] that in humans is encoded by the ''G3BP1'' [[gene]].<ref name="pmid8649363">{{cite journal |vauthors=Parker F, Maurier F, Delumeau I, Duchesne M, Faucher D, Debussche L, Dugue A, Schweighoffer F, Tocque B | title = A Ras-GTPase-activating protein SH3-domain-binding protein | journal = Mol Cell Biol | volume = 16 | issue = 6 | pages = 2561–9 |date=Jul 1996 | pmid = 8649363 | pmc = 231246 | doi =  10.1128/MCB.16.6.2561}}</ref><ref name="pmid9889278">{{cite journal |vauthors=Costa M, Ochem A, Staub A, Falaschi A | title = Human DNA helicase VIII: a DNA and RNA helicase corresponding to the G3BP protein, an element of the ras transduction pathway | journal = Nucleic Acids Res | volume = 27 | issue = 3 | pages = 817–21 |date=Mar 1999 | pmid = 9889278 | pmc = 148252 | doi =10.1093/nar/27.3.817  }}</ref><ref name="entrez">{{cite web | title = Entrez Gene: G3BP1 GTPase activating protein (SH3 domain) binding protein 1| url = https://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=10146}}</ref>
This gene encodes one of the DNA-unwinding enzymes which prefers partially unwound 3'-tailed substrates and can also unwind partial RNA/DNA and RNA/RNA duplexes in an ATP-dependent fashion. This enzyme is a member of the heterogeneous nuclear RNA-binding proteins and is also an element of the Ras signal transduction pathway. It was originally reported to bind specifically to the Ras-GTPase-activating protein by associating with its SH3 domain, but this interaction has recently been challenged.<ref>{{Cite journal

G3BP1 can initiate [[stress granule]] formation and labeled G3BP1 is commonly used as a marker for stress granules.<ref>{{Cite journal|last1=Mahboubi|first1=Hicham|last2=Stochaj|first2=Ursula|date=2017-04-01|title=Cytoplasmic stress granules: Dynamic modulators of cell signaling and disease|journal=Biochimica et Biophysica Acta (BBA) - Molecular Basis of Disease|volume=1863|issue=4|pages=884–895|doi=10.1016/j.bbadis.2016.12.022|pmid=28095315|issn=0925-4439|doi-access=}}</ref>
