WormBase Gene ID  ? WBGene00006496 Gene Name  cgef-1
Sequence Name  ? C14A11.3 Brief Description  cgef-1 encodes a putative guanine nucleotide exchange factor (GEF) and positively regulates CDC-42 during asymmetric division in the embryo; cgef-1 also affects the localization of PAR proteins in the embryo; since cgef-1 mutants exhibit mild phenotypes, cgef-1 may function redundantly with other GEFs to regulate CDC-42 function; CGEF-1 expressed under germline regulatory control is enriched in the nucleoplasm and cell cortex and localizes to the cytoplasm.
Organism  Caenorhabditis elegans Automated Description  Predicted to enable guanyl-nucleotide exchange factor activity. Involved in protein localization. Located in cell cortex and nucleoplasm. Expressed in hermaphrodite gonad; neurons; somatic gonad precursor; and vulva. Is an ortholog of human MCF2 (MCF.2 cell line derived transforming sequence); MCF2L (MCF.2 cell line derived transforming sequence like); and MCF2L2 (MCF.2 cell line derived transforming sequence-like 2).

  Transcripts that showed significantly increased expression in L1 neural cells comparing to in adult neural cells. DESeq2 (v1.18.1) fold change > 2, P-adj<0.05, using BenjaminiHochberg correction. WBPaper00060811:L1_vs_adult_upregulated_neural
  Transcripts of coding genes that showed significantly decreased expression in muscle. DESeq2 (version 1.24.0). Transcripts with a false-discovery rate adjusted p-value less than 0.05 were considered significantly differentially expressed. WBPaper00062325:muscle_depleted_coding-RNA
  Transcripts expressed in neuronal cells, by analyzingfluorescence-activated cell sorted (FACS) neurons. DESeq. False discovry rate (FDR) < 0.1. WBPaper00048988:neuron_expressed
  Genes that showed expression levels higher than the corresponding reference sample (embryonic 24hr 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. WBPaper00037950:all-neurons_L1-larva_expressed

  mRNAs that showed decreased expression in 1 cell mebryo comparing to in oocyte, according to RNAseq analysis. Gaussian error propagation. As cutoff for the up-regulated genes authors used log2 fold change > 1 and P < 0.05 and as cutoff for the down-regulated genes authors used log2 fold change < -1 and P < 0.05.

  Neuronally enriched transcripts according to a comparison of neuronal nuclei IP samples to total nuclei using isolation of nuclei from tagged specific cell types (INTACT) technology. DESEQ2, fold change > 2 and FDR < 0.01. WBPaper00062103:neuron_enriched
Bacteria infection: Enterococcus faecalis Genes with increased expression after 24 hours of infection by E.faecalis Fold changes shown are pathogen vs OP50. For RNA-seq and tiling arrays, log2 fold changes between gene expression values of infected versus uninfected nematodes were calculated. For log2 fold changes > 0.00001 the values > 81.25th percentile were defined as up-regulated and for log2 fold changes < -0.00001 the values < 18.75th percentile were defined as down-regulated.

  Coexpression clique No. 60, 176662_at-Y53F4B.16, on the genome-wide coexpression clique map for the nematode GPL200 platform. All available microarray datasets for the GPL200 platform (Affymetrix C. elegans Genome Array) were obtained from the GEO repository. This included 2243 individual microarray experiments. These were normalized against each other with the software RMAexpress (Bolstad, 2014). Based on these normalized values, Pearsons correlation coefficients were obtained for each probe-probe pair of the 22,620 probes represented on this array type. The resulting list of correlation coefficients was then ranked to generate the ranked coexpression database with information on each probe represented on the GPL200 platform.

  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 that showed significantly increased expression in mrg-1(qa6200) comparing to in control animals in primordial germ cells (PGCs) at L1 larva stage. DESeq2(v1.32.0), FDR < 0.05. WBPaper00064315:mrg-1(qa6200)_upregulated_PGCs
  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.

  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).

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.

  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.
