Activator of bc1 complex (ABC1) kinases, also called aarF domain containing kinase 3; This subfamily is composed of the atypical yeast protein kinase Abc1p, its human homolog ADCK3 (also called CABC1), and similar proteins. Abc1p (also called Coq8p) is required for the biosynthesis of Coenzyme Q (ubiquinone or Q), which is an essential lipid component in respiratory electron and proton transport. It is necessary for the formation of a multi-subunit Q-biosynthetic complex and may also function in the regulation of Q synthesis. Human ADCK3 is able to rescue defects in Q synthesis and the phosphorylation state of Coq proteins in yeast Abc1 (or Coq8) mutants. Mutations in ADCK3 cause progressive cerebellar ataxia and atrophy due to Q10 deficiency. In algae and higher plants, ABC1 kinases have proliferated to more than 15 subfamilies, most of which are located in plastids or mitochondria. Subfamily 13 (ABC1K13) of plant ABC1 kinases belongs in this subfamily with yeast Abc1p and human ADCK3. ABC1 kinases are not related to the ATP-binding cassette (ABC) membrane transporter family.

ABC1 atypical kinase-like domain; This family includes ABC1 from yeast and AarF from E. coli. These proteins have a nuclear or mitochondrial subcellular location in eukaryotes. The exact molecular functions of these proteins is not clear, however yeast ABC1 suppresses a cytochrome b mRNA translation defect and is essential for the electron transfer in the bc 1 complex and E. coli AarF is required for ubiquinone production. It has been suggested that members of the ABC1 family are novel chaperonins. These proteins are unrelated to the ABC transporter proteins.

Mutations in ADCK3 cause progressive cerebellar ataxia and atrophy due to Q10 deficiency. Eukaryotes contain at least two more ABC1/ADCK3-like proteins: in humans, these are the putative atypical protein kinases named ADCK1 and ADCK2. In algae and higher plants, ABC1 kinases have proliferated to more than 15 subfamilies, most of which are located in plastids or mitochondria. Eight of these plant ABC1 kinase subfamilies (ABC1K1-8) are specific for photosynthetic organisms. ABC1 kinases are not related to the ATP-binding cassette (ABC) membrane transporter family.

aarF domain containing kinase 1 and similar proteins; This subfamily is composed of uncharacterized ABC1 kinase-like proteins including the human protein called aarF domain containing kinase 1 (ADCK1). Eukaryotes contain at least three ABC1-like proteins: in humans, these are ADCK3 and the putative protein kinases named ADCK1 and ADCK2. Yeast Abc1p and its human homolog ADCK3 are atypical protein kinases required for the biosynthesis of Coenzyme Q (ubiquinone or Q), which is an essential lipid component in respiratory electron and proton transport. In algae and higher plants, ABC1 kinases have proliferated to more than 15 subfamilies, most of which are located in plastids or mitochondria. Plant subfamilies 14 and 15 (ABC1K14-15) belong to the same group of ABC1 kinases as human ADCK1. ABC1 kinases are not related to the ATP-binding cassette (ABC) membrane transporter family.

Ubiquinone biosynthetic protein UbiB; UbiB is the prokaryotic homolog of yeast Abc1p and human ADCK3 (aarF domain containing kinase 3). It is required for the biosynthesis of Coenzyme Q (ubiquinone or Q), which is an essential lipid component in respiratory electron and proton transport. It is required in the first monooxygenase step in Q biosynthesis. Mutant strains with disrupted ubiB genes lack Q and accumulate octaprenylphenol, a Q biosynthetic intermediate.

Catalytic domain of the Protein Kinase superfamily; The PK superfamily contains the large family of typical PKs that includes serine/threonine kinases (STKs), protein tyrosine kinases (PTKs), and dual-specificity PKs that phosphorylate both serine/threonine and tyrosine residues of target proteins, as well as pseudokinases that lack crucial residues for catalytic activity and/or ATP binding. It also includes phosphoinositide 3-kinases (PI3Ks), aminoglycoside 3'-phosphotransferases (APHs), choline kinase (ChoK), Actin-Fragmin Kinase (AFK), and the atypical RIO and Abc1p-like protein kinases. These proteins catalyze the transfer of the gamma-phosphoryl group from ATP to their target substrates; these include serine/threonine/tyrosine residues in proteins for typical or atypical PKs, the 3-hydroxyl of the inositol ring of D-myo-phosphatidylinositol (PtdIns) or its derivatives for PI3Ks, the 4-hydroxyl of PtdIns for PI4Ks, and other small molecule substrates for APH/ChoK and similar proteins such as aminoglycosides, macrolides, choline, ethanolamine, and homoserine.
