Ras GTPase-activating protein-binding protein 1 is an enzyme that in humans is encoded by the G3BP1 gene.^[1]^[2]^[3]

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 (http://www.ncbi.nlm.nih.gov/pubmed/22205990). Several alternatively spliced transcript variants of this gene have been described, but the full-length nature of some of these variants has not been determined.^[3]

Interactions

G3BP1 has been shown to interact with USP10.^[4] It also interacts with SND1[5].
