The TRIO protein contains 3 functional domains: a serine/threonine kinase domain and 2 guanine nucleotide exchange factor (GEF) domains for the family of Rho-like GTPases, specific for Rac1 (MIM.602048) and RhoA (MIM.165390). These functional domains suggest that this enzyme may play a key role in several signaling pathways that control cell proliferation.
Copy number gains and high-level amplifications of the short arm of chromosome 5 are frequently observed in soft tissue sarcomas.
