Human Gene COQ4 (ENST00000300452.8)
  Description: Homo sapiens coenzyme Q4 (COQ4), transcript variant 1, mRNA; nuclear gene for mitochondrial product. (from RefSeq NM_016035)
RefSeq Summary (NM_016035): This gene encodes a component of the coenzyme Q biosynthesis pathway. Coenzyme Q, an essential component of the electron transport chain, shuttles electrons between complexes I or II to complex III of the mitochondrial transport chain. This protein appears to play a structural role in stabilizing a complex that contains most of the coenzyme Q biosynthesis enzymes. Mutations in this gene are associated with mitochondrial disorders linked to coenzyme Q deficiency. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Apr 2015].

  ID: COQ4_HUMAN
DESCRIPTION: RecName: Full=Ubiquinone biosynthesis protein COQ4 homolog, mitochondrial; AltName: Full=Coenzyme Q biosynthesis protein 4 homolog; Flags: Precursor;
FUNCTION: Component of the coenzyme Q biosynthetic pathway. May play a role in organizing a multi-subunit COQ enzyme complex required for coenzyme Q biosynthesis. Required for steady-state levels of other COQ polypeptides.
PATHWAY: Cofactor biosynthesis; ubiquinone biosynthesis.
SUBUNIT: Component of a multi-subunit COQ enzyme complex, composed of at least COQ3, COQ4, COQ5, COQ6, COQ7 and COQ9 (By similarity).
SUBCELLULAR LOCATION: Isoform 1: Mitochondrion inner membrane; Peripheral membrane protein; Matrix side.
TISSUE SPECIFICITY: Expressed ubiquitously, but at high levels in liver, lung and pancreas.
SIMILARITY: Belongs to the COQ4 family.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
