Ras-GAP SH3 domain binding protein (G3BP1) contains an RNA recognition motif (RRM) and an N-terminal nuclear transport factor 2-like (NTF2-like) domain. It was first identified in a screen for proteins that bind the SH3 domain of the Ras GTPase activating protein (RasGAP). It has been shown to function downstream of Ras and play a role in RNA metabolism, signal transduction, and proliferation. G3BP1 is primarily cytoplasmic but has also been localized to the nucleus. G3BP1 has been shown to be overexpressed in human cancers. Alternate names for G3BP1 include ATP-dependent DNA helicase VIII, and HDH-VIII.
Anti-cDNA FLJ26493 fis, clone KDN06317, highly similar to Ras-GTPase-activating protein binding protein 1
synthetic peptide. The epitope recognized by A302-033A-T maps to a region between residue 275 and 325 of human GTPase activating protein (SH3 domain) binding protein 1 using the numbering given in entry NP_005745.1 (GeneID 10146).
