TRIO trio Rho guanine nucleotide exchange factor [Homo sapiens (human)] - Gene

Summary

Official Symbol: TRIOprovided by HGNC
Official Full Name: trio Rho guanine nucleotide exchange factorprovided by HGNC
Primary source: HGNC:HGNC:12303
See related: Ensembl:ENSG00000038382 MIM:601893; AllianceGenome:HGNC:12303
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Homo sapiens
Lineage: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo
Also known as: tgat; MEBAS; MRD44; MRD63; ARHGEF23
Summary: 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.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

Status: REVIEWED

Description

Transcript Variant: This variant (2) uses an alternate splice site at an internal exon compared to variant 1. This variant is represented as non-coding because the use of the 5'-most expected translational start codon, as used in variant 1, renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
