WormBase Gene ID  ? WBGene00003582 Gene Name  dcap-2
Sequence Name  ? F52G2.1 Brief Description  dcap-2 encodes an mRNA decapping enzyme that is a member of the NUDIX hydrolase (NUcleoside Diphosphate linked to some moiety X) family of enzymes; dcap-2 exhibits sequence- and context-dependent hydrolysis of mRNA caps in vitro, but RNAi experiments indicate that this activity is not essential for embryonic development; DCAP-2 localizes to cytoplasmic mRNA processing bodies and to P granules throughout embryonic development.
Organism  Caenorhabditis elegans Automated Description  Enables 5'-(N(7)-methyl 5'-triphosphoguanosine)-[mRNA] diphosphatase activity. Involved in several processes, including deadenylation-dependent decapping of nuclear-transcribed mRNA; determination of adult lifespan; and response to stress. Located in P granule and P-body. Is an ortholog of human DCP2 (decapping mRNA 2).
Biotype  SO:0001217 Genetic Position  IV :9.46741 ±0.014388

  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 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

  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.

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.

  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.

    Expr3648   The punctate cytoplasmic pattern of AIN-1::GFP resembles that of the P bodies. By using an anti-DCAP-2 antibody, DCAP-2 has been localized to cytoplasmic foci in C. elegans embryos that resembled P bodies (Richard Davis, personal communication). DCAP-2 is the mammalian and yeast homolog of subunit Dcp2 of decapping enzymes that localizes at P bodies. Staining using this antibody and an anti-GFP antibody indicated that AIN-1 was colocalized with DCAP-2 in the embryos. AIN-1::GFP was also observed to be colocalized with a FLAG-tagged DCAP-1 protein at cytoplasmic foci in C. elegans larvae. DCAP-1 is a homolog of mammalian and yeast Dcp1 that are also a subunit of decapping enzymes localized at P bodies.

    Expr3746   Immunostaining of C. elegans embryos revealed that Dcp2 protein was found enriched in particles in the embryonic cytoplasm, and these particles disappear in embryos depleted of Dcp2 using RNAi. Dcp2 staining particles were on average 0.5 +/- 0.03 um in size, and many foci were observed per cell. Although it is difficult to count the exact number of foci in a given cell, the number of Dcp2 enriched bodies per cell more closely resembles the many particles observed in mammalian cells than the 2.4 +/- 1.4 foci per cell observed in yeast. Though present around nuclei in the germ cells of the gonad, cytoplasmic (nonperinuclear) Dcp2 foci were first obvious after fertilization and were present by the time the two pronuclei meet and fuse. By the 2-cell stage, Dcp2 bodies were observed throughout the cytoplasm of both the somatic and germ line lineage, though they often appear stronger in the P-cell than the somatic cell at this early point in development. From the 4-cell stage onward, many Dcp2 foci were observed in the cytoplasm of all cells. Dcp2 staining was faint in nuclei. Somatic CGH-1 foci are coincident with Dcp2. In contrast to previous observations showing that CGH-1 somatic foci disappear after the first few embryonic divisions, cytoplasmic Dcp2 foci persist throughout embryonic development. Dcp2 immunostained C. elegans embryos were colabeled with monoclonal antibodies that stain P-granules (K76 and OIC1D4) and also with anti-GLH-1, which has previously been shown to label P-granules. Such immunostaining indicates that Dcp2 is enriched in P-granules. Dcp2 is also present at sites where P-granules are observed in C. elegans germ cells during oogenesis.
