Short name: Coq4_euk

Overlapping homologous superfamilies


Family relationships


Ubiquinone biosynthesis protein Coq4 is a component of a multi-subunit COQ enzyme complex (composed of at least Coq3, Coq4, Coq5, Coq6, Coq7 and Coq9), which plays a role in the coenzyme Q (ubiquinone) biosynthetic pathway [PMID: 11469793, PMID: 15792955, PMID: 17391640]. Coq4 plays an essential role in organising the COQ enzyme complex and is required for steady-state levels of Coq3, Coq6, Coq7 and Coq9 [PMID: 19022396]. This entry represents eukaryotic Coq4.
