Beyond its canonical translation role, TUFM functions as a dual-localized (mitochondrial and cytosolic) regulator of autophagy and mitophagy by interacting with the ATG5–ATG12–ATG16L1 complex, Beclin-1, and NLRX1, and it suppresses RIG-I-mediated type I interferon signaling during viral infection [PMID:22749352, PMID:33113344]. TUFM's autophagy-promoting activity is tuned by multiple post-translational modifications: PINK1 phosphorylation at Ser222 converts TUFM from a mitophagy activator to a cytosolic suppressor, MRG15-mediated deacetylation at K82/K91 targets it for ClpXP degradation, RNF185-catalyzed K27-linked ubiquitination enables SQSTM1–LC3-dependent mitophagy, and lactylation at K286 impairs TOMM40-mediated mitochondrial import [PMID:33113344, PMID:35985547, PMID:38084826, PMID:39496783]. Loss-of-function mutations in TUFM cause combined oxidative phosphorylation deficiency 4 (COXPD4), presenting as severe lactic acidosis with leukodystrophy or dilated cardiomyopathy [PMID:17160893, PMID:30903008].\",\n  \"teleology\": [\n    {\n      \"year\": 1993,\n      \"claim\": \"Structural determination of EF-Tu in both GTP and GDP states revealed how a large interdomain rotation (~90°) upon GTP binding exposes the aminoacyl-tRNA binding cleft, establishing the conformational switch mechanism underlying translational GTPase function.\",\n      \"evidence\": \"X-ray crystallography of Thermus aquaticus EF-Tu in GTP vs. GDP forms\",\n      \"pmids\": [\"8069622\"],\n      \"confidence\": \"High\",\n      \"gaps\": [\"Mitochondrial EF-Tu structure not yet solved\", \"Ribosome-bound conformation unknown\"]\n    },\n    {\n      \"year\": 1995,\n      \"claim\": \"The crystal structure of the EF-Tu·GTP·aminoacyl-tRNA ternary complex resolved how EF-Tu simultaneously contacts the aminoacylated CCA end and the T-stem of tRNA across all three domains, and revealed molecular mimicry with EF-G, explaining their shared ribosomal binding site.\",\n      \"evidence\": \"2.7 Å X-ray crystallography of Thermus aquaticus EF-Tu·GDPNP·aa-tRNA complex\",\n      \"pmids\": [\"7491491\"],\n      \"confidence\": \"High\",\n      \"gaps\": [\"Ribosome context not included\", \"Mitochondrial-specific features not addressed\"]\n    },\n    {\n      \"year\": 1997,\n      \"claim\": \"Cloning and characterization of the human TUFM gene defined its genomic organization (9 introns, chromosome 16p11.2) and encoded a 455-residue protein with an N-terminal mitochondrial targeting sequence, establishing the molecular identity of the human mitochondrial translation factor.\",\n      \"evidence\": \"cDNA cloning, Northern blot, FISH chromosomal mapping\",\n      \"pmids\": [\"9332382\"],\n      \"confidence\": \"High\",\n      \"gaps\": [\"No functional assays performed\", \"Protein localization beyond mitochondria not examined\"]\n    },\n    {\n      \"year\": 2000,\n      \"claim\": \"The crystal structure of bovine mitochondrial EF-Tu·GDP revealed conserved three-domain architecture but altered domain orientations and reduced nucleotide affinity compared to bacterial orthologs, explaining the requirement for the dedicated mitochondrial guanine nucleotide exchange factor EF-Ts.\",\n      \"evidence\": \"1.94 Å X-ray crystallography of bovine mitochondrial EF-Tu·GDP\",\n      \"pmids\": [\"10715211\"],\n      \"confidence\": \"High\",\n      \"gaps\": [\"GTP-bound mitochondrial structure not solved\", \"C-terminal zinc-finger-like extension function not tested\"]\n    },\n    {\n      \"year\": 2003,\n      \"claim\": \"Overexpression of EF-Tu in yeast corrected respiratory defects, mitochondrial morphology, and mtDNA instability caused by MELAS-equivalent tRNA mutations, providing the first functional evidence that EF-Tu abundance can compensate for defective mitochondrial tRNAs.\",\n      \"evidence\": \"Multicopy suppression in yeast mitochondrial transformation with respiratory growth assays\",\n      \"pmids\": [\"12524521\"],\n      \"confidence\": \"Medium\",\n      \"gaps\": [\"Yeast system;
