WormBase Gene ID  ? WBGene00006875 Gene Name  vab-9
Sequence Name  ? T22C8.8 Brief Description  vab-9 encodes a claudin homolog orthologous to human brain cell membrane protein 1 (BCMP1) and Drosophila CG6982; VAB-9 colocalizes with HMP-1 to an apical layer of the adherens junctions of all epithelial cells, one layer more apically than AJM-1; vab-9 mutants have disorganized F-actin at the adherens junction, implying that VAB-9 links junctions to circumferential actin filaments; VAB-9 is also expressed in the nerve ring; VAB-9 requires the cadherin HMR-1 to localize to the cell membrane, and both alpha-catenin (HMP-1) and beta-catenin (HMP-2) to remain at the cell junction after membrane localization.
Organism  Caenorhabditis elegans Automated Description  Involved in cell-cell adhesion; defense response to Gram-negative bacterium; and innate immune response. Located in cell junction. Expressed in epithelial cell; hypodermis; and nerve ring. Human ortholog(s) of this gene implicated in erythrokeratodermia variabilis and mutilating palmoplantar keratoderma with periorificial keratotic plaques. Is an ortholog of human TMEM47 (transmembrane protein 47).

  Transcripts expressed in neuronal cells, by analyzingfluorescence-activated cell sorted (FACS) neurons. DESeq. False discovry rate (FDR) < 0.1. WBPaper00048988:neuron_expressed
adult vs dauer larva Transcripts that showed differential expression in adult vs dauer lava in N2 animals at 20C. N.A. WBPaper00050488:adult_vs_dauer_regulated_N2_20C
  TGF- Dauer pathway adult transcriptional targets. Results obtained by comparing the microarray results of the dauer-constitutive mutants daf-7(e1372), daf-7(m62), and daf-1(m40) with dauer-defective mutants daf-3(mgDf90), daf-5(e1386), and daf-7(e1372);daf-3(mgDf90) double mutants at the permissive temperature, 20C, on the first day of adulthood. SAM WBPaper00031040:TGF-beta_adult_upregulated
Osmotic stress Transcripts that showed significantly altered expression with 500 mM salt (NaCl) vs 100 mM salt when food was present DESeq(version 1.10.1), FDR < 0.05. WBPaper00050726:OsmoticStress_regulated_Food
  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.

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.

  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 aak-1(tm1944);aak-2(ok524) animals comparing to in N2. DEseq 1.18.0, adjusted p-value < 0.05. WBPaper00056471:aak-1(tm1944);aak-2(ok524)_upregulated
  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.
