G3BP are scaffolding proteins linking signal transduction to RNA metabolismand belongs to a evolutionarily conversed family throughout eukaryota. G3BP exists in three isoforms G3BP1, 2a and 2b which are the products of two distinct genes. The proteins are relatively ubiquitously expressed. G3BP1 plays an potential role in cell cycle regulation. G3BP1 also bind and regulate cmyc which is an important transcription factorpredominantly involved in the regulation of cell cycle progression. The protein acts as a major 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. Over-expression of G3BP1 has been observed in a range of human tumors, including breast, head and neck, colon and thyroid.
