Carbamoyl-phosphate synthetase 2, aspartate transcarbamylase, and dihydroorotase
Aspartate Carbamoyltransferase, Dihydroorotase, ura4
The de novo synthesis of pyrimidine nucleotides is required for mammalian cells to proliferate. This gene encodes a trifunctional protein which is associated with the enzymatic activities of the first 3 enzymes in the 6-step pathway of pyrimidine biosynthesis: carbamoylphosphate synthetase (CPS II), aspartate transcarbamoylase, and dihydroorotase. This protein is regulated by the mitogen-activated protein kinase (MAPK) cascade, which indicates a direct link between activation of the MAPK cascade and de novo biosynthesis of pyrimidine nucleotides.

Versatile function of the circadian protein CIPC as a regulator of Erk activation.
New
Shōbara, Japan. In Biochem Biophys Res Commun, Feb 2016
We identified CIPC-binding proteins such as the multifunctional enzyme CAD protein (carbamoyl-phosphate synthetase 2, aspartate transcarbamoylase, and dihydroorotase), which is a key enzyme for de novo pyrimidine synthesis.

New
Milano, Italy. In Br J Cancer, Jan 2016
RESULTS: A novel ALK fusion with the carbamoyl-phosphate synthetase 2, aspartate transcarbamylase, and dihydroorotase (CAD) gene (CAD-ALK fusion gene) was identified.
New cassettes for single-step drug resistance and prototrophic marker switching in fission yeast.
New
Aberdeen, United Kingdom. In Yeast, Dec 2015
Moreover, strains with single gene deletions or tags often already exist in strain collections; for historical reasons these will mostly carry the ura4(+) gene or the G418-resistance kanMX as marker.
Diversion of aspartate in ASS1-deficient tumours fosters de novo pyrimidine synthesis.
New
Impact
Israel. In Nature, Dec 2015
Here we show that decreased activity of ASS1 in cancers supports proliferation by facilitating pyrimidine synthesis via CAD (carbamoyl-phosphate synthase 2, aspartate transcarbamylase, and dihydroorotase complex) activation.
A vector system for efficient and economical switching of a ura4(+) module to three commonly used antibiotic marker cassettes in Schizosaccharomyces pombe.
New
Xiamen, China. In Yeast, Nov 2015
We describe here the development of a set of plasmid vectors that allow simple, efficient and economical switching of a ura4(+) module in existing Schizosaccharomyces pombe strains to any of the three routinely used antibiotic marker cassettes, kanMX6, hphMX6 and natMX6.

Schizosaccharomyces pombe Δura4 cells lyse when grown on YPD medium.
Stimulation of de novo pyrimidine synthesis by growth signaling through mTOR and S6K1.
Impact
Boston, United States. In Science, 2013
mTORC1 signaling posttranslationally regulated this metabolic pathway via its downstream target ribosomal protein S6 kinase 1 (S6K1), which directly phosphorylates S1859 on CAD (carbamoyl-phosphate synthetase 2, aspartate transcarbamoylase, dihydroorotase), the enzyme that catalyzes the first three steps of de novo pyrimidine synthesis.
Quantitative phosphoproteomics reveal mTORC1 activates de novo pyrimidine synthesis.
Impact
Basel, Switzerland. In Science, 2013
mTOR controlled the phosphorylation of 335 proteins, including CAD (carbamoyl-phosphate synthetase 2, aspartate transcarbamylase, and dihydroorotase).
Identification of CAD as an androgen receptor interactant and an early marker of prostate tumor recurrence.
GeneRIF
Villejuif, France. In Faseb J, 2012
findings show that in prostate tumor cells, CAD fosters androgen receptor translocation into the nucleus and stimulates its transcriptional activity; in radical prostatectomy specimens, CAD expression was not correlated with proliferation markers, but a higher CAD mRNA level was associated with local tumor extension and cancer relapse
Dare to challenge the silence? Telomeric gene silencing revisited.
Review
Guelph, Canada. In Nucleus, 2011
The gene silencing analyses in these species very often include the FOA-sensitivity assay, which detects the suppression of a reporter gene (URA3 in S. cerevisiae and URA4 in S. pombe) inserted at genomic locations of choice.
Leflunomide: a drug with a potential beyond rheumatology.
Review
Köln, Germany. In Immunotherapy, 2010
Leflunomide, an inhibitor of the dihydroorotase dehydrogenase and thereby pyrimidine synthesis, was introduced and licensed for the treatment of rheumatoid arthritis in 1998.

Review
Suzhou, China. In Acta Biochim Biophys Sin (shanghai), 2007
The generation of CDP/Cux p110 stimulates the expression of reporter plasmid containing the promoter sequences of some S phase-specific-genes such as DNA polymerase a gene, dihydrofolate reductase gene, carbamoyl-phosphate synthase/aspartate carbamoyl-transferase/dihydroorotase gene, and cyclin A gene.

Review
Boston, United States. In Cold Spring Harb Symp Quant Biol, 2005
In support of this possibility, tethering of the RITS complex to the transcript of the normally euchromatic ura4 (+) gene results in siRNA generation and RNAi- and heterochromatin-dependent silencing of the ura4 (+) gene.

The CP channelling complex involving CKase and OTCase or ATCase (aspartate carbamoyltransferase), identified in hyperthermophilic archaea, provides a good model system to investigate the mechanism of metabolic channelling and the molecular basis of protein-protein interactions in the physiology of extreme thermophiles.
