Protein

Tetratricopeptide repeat protein 19, mitochondrial

Gene

TTC19

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Required for the preservation of the structural and functional integrity of mitochondrial respiratory complex III by allowing the physiological turnover of the Rieske protein UQCRFS1 (PubMed:21278747, PubMed:28673544). Involved in the clearance of UQCRFS1 N-terminal fragments, which are produced upon incorporation of UQCRFS1 into the complex III and whose presence is detrimental for its catalytic activity (PubMed:28673544).2 Publications

Caution

Was reported to be required for the abcission step in cytokinesis, possibly regulating the ESCRT-III complex via its interaction with CHMP4B (PubMed:20208530). According to the same authors, localizes to the centrosome during all stages of the cell cycle and is recruited to the midbody during cytokinesis (PubMed:20208530). However, the midbody localization could not be confirmed by others (PubMed:21278747).2 Publications
