WormBase Gene ID  ? WBGene00019127 Gene Name  cgt-3
Sequence Name  ? F59G1.1 Brief Description  cgt-3 encodes a transmembrane protein that is one of three C. elegans ceramide glucosyltransferases; by homology, CGT-3 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-3 mutant worms show no obvious defects, animals doubly mutant for cgt-3 and cgt-1 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-3::GFP reporter fusion is expressed in pharyngeal tissues, the intestine, the pharyngeal-intestinal and intestinal-rectal valves, the rectal gland cells, head mesodermal cells and additional unidentified head cells; cgt-3 expression in mouse GM95 cells, deficient in glucosylceramide due to a defect in glucosylceramide synthase, confirms that CGT-3 has ceramide glucosyltransferase activity.
Organism  Caenorhabditis elegans Automated Description  Predicted to enable ceramide glucosyltransferase activity. Involved in several processes, including glucosylceramide biosynthetic process; regulation of mesodermal cell fate specification; and regulation of protein localization to basolateral plasma membrane. Located in plasma membrane. Expressed in several structures, including germ line; pharyngeal muscle cell; pharyngeal-intestinal valve; rectal gland cell; and rectal valve cell. Is an ortholog of human UGCG (UDP-glucose ceramide glucosyltransferase).
Biotype  SO:0001217 Genetic Position  II :-0.853217 ±0.000266

  Transcripts expressed in intestine, according to PAT-Seq analysis using Pges-1-GFP-3XFLAG mRNA tagging. Cufflinks FPKM value >=1. WBPaper00050990:intestine_expressed
  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

  Transcripts expressed in pharynx, according to PAT-Seq analysis using Pmyo-2-GFP-3XFLAG mRNA tagging. Cufflinks FPKM value >=1. WBPaper00050990:pharynx_expressed
  Genes with expression level regulated by genotype (N2 vs CB4856) and age at old adults stage (214 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_aging
  Transcripts expressed in seam cells, according to PAT-Seq analysis using Pgrd-10-GFP-3XFLAG mRNA tagging. Cufflinks FPKM value >=1. WBPaper00050990:seam_expressed
  Strictly maternal class (SM): genes that are the subset of maternal genes that are not also classified as embryonic. 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_SM
  Transcripts detected in body muscle nuclei according to a nuclear FACS-based strategy. Cufflinks WBPaper00065120:body-muscle-transcriptome
  Genes that showed expression levels higher than the corresponding reference sample (L2 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.

Strain: BC14136 [F59G1.1a::gfp] transcriptional fusion. PCR products were amplified using primer A: 5' [AAACTCCCAAAAGTTGTAGTTTGC] 3' and primer B 5' [TTTGCACTGAAAAGGCGTC] 3'. Expr6269 Adult Expression: pharynx; intestine; head mesodermal cell; seam cells; Larval Expression: pharynx; intestine; head mesodermal cell; seam cells;  
Picture: Figure 4A to 4C.   Expr8290 Expressed in pharynx, spermatheca, gut, anal cells.  
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.   Expr8572 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). Some cgt-3::gfp expression was also visible in head mesodermal cells.  
    Expr11539 CGT-3::EGFP was expressed in pharyngeal intestinal valve, intestinal rectal valve and hypodermis. In transgenic rescue experiment, relatively weak but definite expression of the cgt-3 gene was detected also in the germline. Searching the in situ hybridization database (see NEXTDB online at http://nematode.lab.nig.ac.jp/ ) with cgt sequences revealed that the cgt-3 gene is expressed in the gonad of adult hermaphrodites. Serial analysis of gene expression (SAGE) by Wang et al. (2009) also showed that cgt-3 is among a set of 603 germline-specific/enriched genes identified only by SAGE.
