WormMine: Gene WBGene00004259

• WormBase Gene ID: WBGene00004259
• Gene Name: pyr-1
• Sequence Name: D2085.1
• Brief Description: pyr-1 encodes the C. elegans protein CAD which is orthologous to the human gene Carbamyl phosphate synthetase I (CPS1); pyr-1 encodes a single protein with predicted carbamoyl phosphate synthetase, aspartate transcarbamoylase, and dihydroorotase activities (CAD), which is involved in pyrimidine biosynthesis; pyr-1 mutants can be rescued by the supply of exogenous pyrimidines; genetic interaction studies indicate that pyr-1 may function upstream of sqv-1, sqv-2, rib-1 and rib-2, genes involved in heparan sulphate proteoglycan biosynthesis, by providing pyrimidine for nucleotide sugars essential for the synthesis of heparan sulphate proteoglycan; pyr-1 is essential for viability and for proper morphogenesis of the pharynx, indicating that proteoglycan synthesis is essential for pharyngeal organogenesis.
• Organism: Caenorhabditis elegans
• Automated Description: Predicted to enable aspartate carbamoyltransferase activity and dihydroorotase activity. Predicted to contribute to carbamoyl-phosphate synthase (glutamine-hydrolyzing) activity. Involved in several processes, including nematode pharyngeal gland morphogenesis; nematode pharynx development; and pyrimidine nucleobase biosynthetic process. Predicted to be located in cytosol. Expressed in intestine. Used to study carbamoyl phosphate synthetase I deficiency disease and orotic aciduria. Human ortholog(s) of this gene implicated in developmental and epileptic encephalopathy 50. Is an ortholog of human CAD (carbamoyl-phosphate synthetase 2, aspartate transcarbamylase, and dihydroorotase).

	Maternal class (M): genes that are called present in at least one of the three PC6 replicates.	A modified Welch F statistic was used for ANOVA. For each gene, regressed error estimates were substituted for observed error estimates. The substitution is justified by the lack of consistency among the most and least variable genes at each time point. Regressed error estimates were abundance-dependent pooled error estimates that represented a median error estimate from a window of genes of similar abundance to the gene of interest. A randomization test was used to compute the probability Pg of the observed F statistic for gene g under the null hypothesis that developmental time had no effect on expression. P-values were not corrected for multiple testing.	[cgc5767]:expression_class_M

	Genes with expression level regulated by genotype (N2 vs CB4856) and age at L3 larva and Late reproduction stage (96 hours at 24 centigrade).	For model 2, authors used 100 permutations to estimate the FDR threshold. Per permutation, genotypes and ages were independently randomly distributed, keeping the among-gene structure intact. Then for each spot (23,232) on the array, model 2 was tested. The obtained P-values were used to estimate a threshold for each of the explanatory factors. Authors also used a genome-wide threshold of -log10 P-value = 2, which resembles an FDR of 0.072 and 0.060 for marker and the interaction age-marker for the developing worms and FDR of 0.050 and 0.065 for marker and age-marker for the aging worms. For the physiological age effect, authors used a log10 P-value = 8 in developing worms (0.012 FDR) and -log10 P-value = 6 (0.032 FDR).	WBPaper00040858:eQTL_age_regulated_developing

	Expression Pattern Group C, enriched for genes involved in metabolic processes.	The significance (P 0.0001) of the relative age (time) was used to determine if a gene was differentially expressed between the three age (time) groups. The effect of this factor explaining gene expression differences was used to determine if the expression went up or down during the two age/time periods (t1 - t2 and t2 -t3). Authors used a permutation approach to determine the thresholds for the different mapping strategies. For each of the used models for eQTL mapping, authors used 23,000 permutations. For each permutation, authors randomly picked a spot; each spot could only be picked once. The gene expression and relative lifespan values were than randomly distributed over the RILs (and time points) and used for mapping. In this way, authors obtained a threshold for each of the explaining factors. For the single time points, authors used a FDR of 0.01 to adjust for multiple testing. The genome-wide threshold for this FDR is -log10 P = 3.8 for each of the three time points. For the combined models (t1 to t2 and t2 to t3), authors used a genome-wide threshold of -log10 P = 4, which resembles an FDR of 0.006, 0.001, and 0.006 for marker, age, and the interaction between marker and age, respectively. To determine the threshold for the single gene examples, authors used 1000 permutations as in the genome-wide threshold. The difference is that they use the gene under study in all of the permutations. The P-values for the gene specific thresholds were determined at FDR = 0.05.	WBPaper00036286:Pattern_C

	Proteins that showed significantly decreased expression after 1-day-old wild type adults were exposed to cisplatin (300ug per mL) for 6 hours.	The differential expression analysis was performed in R. Differentially expressed proteins were identified by using a two-sided t-test on log-transformed data.

	Proteins that showed significantly decreased expression in 1-day-old sek-1(km4) adults comparing to in wild type animals, both with 6 hours of cisplatin treatment.	The differential expression analysis was performed in R. Differentially expressed proteins were identified by using a two-sided t-test on log-transformed data.	WBPaper00065373:sek-1(km4)_downregulated_cisplatin
	Genes that showed oscillating mRNA expression level throughout the 16 hour time courses from L3 larva to young adult.	The following three lines of R code were used to perform the classification: increasing <-2*amplitude-PC1 < -1.7; oscillating <-!increasing & (amplitude > 0.55); flat <-!increasing & !oscillating; Note that the amplitude of a sinusoidal wave corresponds to only half the fold change between trough and peak.

6 Expression Patterns

• Primary Identifier: Expr7805
• Remark: Picture: Figure 4.
• Pattern: pyr-1::gfp was expressed in all cells of the embryo beginning during gastrulation after the second division of the gut precursor E cell (the 4E stage; approximately 115 to 185 min. post first cleavage). Strong GFP expression continued in the gut until the bean stage (approximately 350 to 390 min. post first cleavage), but progressively declined in other cell types. pyr-1::gfp expression was undetectable in later stage embryos but reappeared in the gut after hatching in L1 larvae through adults. This pattern of widespread expression in the embryo and gut expression in larvae is consistent with in situ hybridization results.
