Catalytic domain of the atypical protein serine kinase, Eukaryotic RIO1 kinase; RIO1 is present in archaea, bacteria and eukaryotes. This subfamily is composed of RIO1 proteins from eukaryotes. RIO1 is essential for survival and is required for 18S rRNA processing, proper cell cycle progression and chromosome maintenance. It is associated with precursors of 40S ribosomal subunits, just like RIO2. Although depletion of either RIO1 and RIO2 results in similar effects, the two kinases are not fully interchangeable. RIO kinases are atypical protein serine kinases containing a kinase catalytic signature, but otherwise show very little sequence similarity to typical PKs. Serine kinases catalyze the transfer of the gamma-phosphoryl group from ATP to serine residues in protein substrates. The RIO catalytic domain is truncated compared to the catalytic domains of typical PKs, with deletions of the loops responsible for substrate binding. The RIO kinase catalytic domain family is part of a larger superfamily, that includes the catalytic domains of other kinases such as the typical serine/threonine/tyrosine protein kinases (PKs), aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase (PI3K). : Pssm-ID: 270698 Cd Length: 190 Bit Score: 410.04 E-value: 3.54e-143

Catalytic domain of the atypical protein serine kinases, RIO kinases; RIO kinases are atypical protein serine kinases present in archaea, bacteria and eukaryotes. Serine kinases catalyze the transfer of the gamma-phosphoryl group from ATP to serine residues in protein substrates. RIO kinases contain a kinase catalytic signature, but otherwise show very little sequence similarity to typical PKs. The RIO catalytic domain is truncated compared to the catalytic domains of typical PKs, with deletions of the loops responsible for substrate binding. Most organisms contain at least two RIO kinases, RIO1 and RIO2. A third protein, RIO3, is present in multicellular eukaryotes. In yeast, RIO1 and RIO2 are essential for survival. They function as non-ribosomal factors necessary for late 18S rRNA processing. RIO1 is also required for proper cell cycle progression and chromosome maintenance. The biological substrates for RIO kinases are still unknown. The RIO kinase catalytic domain family is part of a larger superfamily, that includes the catalytic domains of other kinases such as the typical serine/threonine/tyrosine protein kinases (PKs), aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase (PI3K).

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.

Choline Kinase and similar proteins; This subfamily is composed of bacterial and eukaryotic choline kinases, as well as eukaryotic ethanolamine kinase. ChoK catalyzes the transfer of the gamma-phosphoryl group from ATP (or CTP) to its substrate, choline, producing phosphorylcholine (PCho), a precursor to the biosynthesis of two major membrane phospholipids, phosphatidylcholine (PC), and sphingomyelin (SM). Although choline is the preferred substrate, ChoK also shows substantial activity towards ethanolamine and its N-methylated derivatives. Bacterial ChoK is also referred to as licA protein. ETNK catalyzes the transfer of the gamma-phosphoryl group from CTP to ethanolamine (Etn), the first step in the CDP-Etn pathway for the formation of the major phospholipid, phosphatidylethanolamine (PtdEtn). Unlike ChoK, ETNK shows specific activity for its substrate and displays negligible activity towards N-methylated derivatives of Etn. ChoK plays an important role in cell signaling pathways and the regulation of cell growth. The ChoK subfamily is part of a larger superfamily that includes the catalytic domains of other kinases, such as the typical serine/threonine/tyrosine protein kinases (PKs), RIO kinases, actin-fragmin kinase (AFK), and phosphoinositide 3-kinase (PI3K).
