Atypical kinase ADCK3, mitochondrial

Gene

Organism
Rattus norvegicus (Rat)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at transcript leveli

Functioni

Atypical kinase involved in the biosynthesis of coenzyme Q, also named ubiquinone, an essential lipid-soluble electron transporter for aerobic cellular respiration. Its substrate specificity is unclear: either acts as protein kinase that phosphorylates other proteins in the CoQ complex to stabilize their interactions or acts as a small molecule kinase that phosphorylates a prenyl lipid in the ubiquinone biosynthesis pathway. Shows an unusual selectivity for binding ADP over ATP.By similarity

Enzyme regulationi

Autoinhibited by the N-terminal domain, containing the KxGQ motif, that completely occludes the typical substrate binding pocket.By similarity

Pathwayi: ubiquinone biosynthesis

This protein is involved in the pathway ubiquinone biosynthesis, which is part of Cofactor biosynthesis.By similarity

Domaini

Adopts an atypical protein kinase-like fold: while it adopts a core fold similar to that of well-characterized protein kinase-like domains, a number of features are positioned to inhibit the kinase activity: (1) an atypical AAAS motif in an alanine-rich (A-rich) loop that replaces the canonical glycine-rich (G-rich) nucleotide-binding loop and limits ATP binding by establishing an unusual selectivity for ADP and (2) an N-terminal domain, containing the KxGQ motif, that completely occludes the typical substrate binding pocket.By similarity
