WormMine: Gene WBGene00011517

• WormBase Gene ID: WBGene00011517
• Gene Name: cgt-1
• Sequence Name: T06C12.10
• Brief Description: cgt-1 encodes a transmembrane protein that is one of three C. elegans ceramide glucosyltransferases; by homology, CGT-1 is predicted to localize to the Golgi membrane and catalyze the transfer of glucose from UDP-glucose to ceramide to synthesize glucosylceramide, a glycosphingolipid precursor; although cgt-1 mutant worms show no obvious defects, animals doubly mutant for cgt-1 and cgt-3 arrest development in the early L1 larval stage, showing impaired feeding ability; in addition, cgt-3;cgt-1 and cgt-3;cgt-1;cgt-2 mutant animals show reduced glucosylceramide levels; a CGT-1::GFP reporter fusion is expressed in pharyngeal tissues, the intestine, the pharyngeal-intestinal and intestinal-rectal valves, the rectal gland cells, unidentified head cells, and the excretory system; cgt-1 expression in the intestine is sufficient to rescue the defects of cgt-3;cgt-1 mutant animals.
• Organism: Caenorhabditis elegans
• Automated Description: Predicted to enable ceramide glucosyltransferase activity. Involved in glucosylceramide biosynthetic process; nematode larval development; and regulation of protein localization to basolateral plasma membrane. Predicted to be located in membrane. Expressed in several structures, including excretory system; pharyngeal muscle cell; pharyngeal-intestinal valve; rectal gland cell; and rectal valve cell. Is an ortholog of human UGCG (UDP-glucose ceramide glucosyltransferase).

For each gene in each microarray hybridization experiment, the ratio of RNA levels from the two samples was transformed into a log2 value and the mean log2 ratio was calculated. The log2 ratios were normalized by print-tip Loess normalization (Dudoit and Yang, 2002). All genes with a false discovery rate of <= 5% (q <= 0.05) (Storey and Tibshirani, 2003) and a mean fold-change ratio of >= 1.5 were selected for further analysis.

	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.	WBPaper00044736:oscillating_dev_expression
	Transcripts that showed significantly increased expression in nuo-6(qm200) comparing to in N2.	Differential gene expression analysis was performed using the quasi-likeli-hood framework in edgeR package v. 3.20.1 in R v. 3.4.1.	WBPaper00053810:nuo-6(qm200)_upregulated
	Transcripts that showed significantly increased expression in hda-1(ne4752[3xFLAG-Degron-HDA-1]) in gonads dissected from 1-day old adult animals.	Salmon was used to map the mRNA-seq reads with the worm database WS268, and its output files were imported to DESeq2 in R. The differentially expressed genes were filtered by fold change more than 2 and adjusted p-value < 0.05. The scatter plots were generated by the plot function in R.	WBPaper00061479:hda-1(ne4752)_upregulated
	Genes that showed expression levels higher than the corresponding reference sample (L3/L4 all cell reference).	A Mann-Whitney U test with an empirical background model and FDR correction for multiple testing was used to detect expressed transcripts (Benjamini and Hochberg 1995). Genes and TARs with an FDR <= 0.05 were reported as expressed above background. Authors detected differentially expressed transcripts using a method based on linear models. Genes and TARs were called differentially expressed if the FDR was <= 0.05 and the fold change (FC) >= 2.0. To more strictly correct for potential false-positives resulting from multiple sample comparisons, authors divided individual FDR estimates by the number of samplesor sample comparisons, respectively. This resulted in an adjusted FDR of 1.3 * 0.0001 for expression above background and of 7.4 * 0.0001 for differential expression. Authors called genes selectively enriched in a given tissue if they met the following requirements: (1) enriched expression in a given tissue (FDR <= 0.05 and FC >= 2.0), (2) fold change versus reference among the upper 40% of the positive FC range observed for this gene across all tissues, and (3) fold-change entropy among the lower 40% of the distribution observed for all genes.

7 Expression Patterns

• Primary Identifier: Expr2009946
• Pattern: Single cell embryonic expression. Only cell types with an expression fraction of greater 0.2 of the maximum expressed fraction are labeled (Full data can be downloaded from http://caltech.wormbase.org/pub/wormbase/datasets-published/packer2019/). The colors represent the broad cell class to which the cell type has been assigned. The size of the point is proportional to the log2 of the numbers of cells in the dataset of that cell type.

• Primary Identifier: Expr8571
• Remark: Both cgt-1 and cgt-3 showed additional, non-overlapping, expression in some non-identified head cells. With the possible exception of a few amphid neurons, authors could not detect any expression of cgt-1 or cgt-3 in the nervous system. Picture: Fig. 6.
• Pattern: Both cgt-1::gfp and cgt-3::gfp were strongly expressed in pharyngeal muscles and in other pharyngeal cells, although their expression did not completely overlap. In addition, they showed strong expression in the pharyngeal intestinal valve (PIV), in the intestinal cells (particularly the most anterior and the most posterior), in the intestinal rectal valve (IRV), and in the three rectal gland cells (RGCs). cgt-1::gfp expressed in the excretory cell, excretory canals, duct cell and pore cell.
