DESCRIPTION

Also known as TRIO_HUMAN, TRIO. Guanine nucleotide exchange factor (GEF) for RHOA and RAC1 GTPases (PubMed:8643598, PubMed:22155786, PubMed:27418539). Involved in coordinating actin remodeling, which is necessary for cell migration and growth (PubMed:10341202, PubMed:22155786). Plays a key role in the regulation of neurite outgrowth and lamellipodia formation (PubMed:32109419). In developing hippocampal neurons, limits dendrite formation, without affecting the establishment of axon polarity. Once dendrites are formed, involved in the control of synaptic function by regulating the endocytosis of AMPA-selective glutamate receptors (AMPARs) at CA1 excitatory synapses (By similarity). May act as a regulator of adipogenesis (By similarity). Interacts with CARMIL1 (PubMed:19846667). Interacts with PTPRF/LAR (PubMed:8643598). Interacts with ANKRD26 (PubMed:22666460). Interacts with Bassoon/BSN and Piccolo/PCLO (By similarity). Interacts with the cytoplasmic region of the heterodimer formed by NGFR and SORCS2. ProNGF binding mediates dissociation of TRIO from the receptor complex (PubMed:22155786).
