This gene encodes a large protein that functions as a GDP to GTP exchange factor. This protein promotes the reorganization of the actin cytoskeleton, thereby playing a role in cell migration and growth. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2015]
GeneCards Summary for TRIO Gene
TRIO (Trio Rho Guanine Nucleotide Exchange Factor) is a Protein Coding gene. Diseases associated with TRIO include Intellectual Developmental Disorder, Autosomal Dominant 44, With Microcephaly and Intellectual Developmental Disorder, Autosomal Dominant 63, With Macrocephaly. Among its related pathways are NGF Pathway and RET signaling. Gene Ontology (GO) annotations related to this gene include transferase activity, transferring phosphorus-containing groups and protein tyrosine kinase activity. An important paralog of this gene is KALRN.
UniProtKB/Swiss-Prot Summary for TRIO Gene
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). 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).
GTPases are a group of enzymes that catalyze hydrolysis of the gamma phosphate bond in guanine triphosphate (GTP) to form guanine diphosphate (GDP). Mg2+ ions are essential for catalytic activity. GTPases, often coupled to G proteins, are essential in signal transduction.
