26642043 GTPBP3 defective expression is associated with an mitochondrial-tRNA hypomodification status.GTPBP3 plays a role in the regulation of UCP2 and MCP1 proteins through AMPK signaling.
25434004 Most individuals with GTPBP3 mutations developed neurological symptoms and MRI involvement of thalamus, putamen, and brainstem resembling Leigh syndrome.
25149473 Results show that post-transcriptional expression of GTPBP3, MTO1 and TRMU genes is down-regulated, leading to mt-tRNA hypomodification and contributing to mitochondrial dysfunction in MELAS cybrids.
20877624 Observational study of gene-disease association. (HuGE Navigator)
19209188 Meta-analysis of gene-disease association. (HuGE Navigator)
18852288 Data show that the two most abundant GTPBP3 isoforms exhibit moderate affinity for guanine nucleotides like their bacterial homologue, MnmE, although they hydrolyze GTP at a 100-fold lower rate.
15542390 Phenotype of non-syndromic deafness associated with the mitochondrial A1555G mutation is modulated by mitochondrial RNA modifying enzymes MTO1 and GTPBP3.
12370316 GTPBP3 localizes in the mitochondria and is a deafness-associated homolog of yeast MSS1.
