WormBase Gene ID  ? WBGene00010036 Gene Name  cpar-1
Sequence Name  ? F54C8.2 Brief Description  cpar-1 encodes one of two C. elegans proteins homologous to the inner kinetochore histone H3 variant CENP-A (the other is encoded by hcp-3); loss of cpar-1 and hcp-3 activity via RNAi results in mitotic chromosome segregation defects, but no significant defects in meiotic chromosome segregation; when expressed in the germline using the pie-1 promoter, a CPAR-1::GFP fusion protein localizes to meiotic chromosomes during late prophase/prometaphase of meiosis I, but is not seen on chromosomes during meiosis II.
Organism  Caenorhabditis elegans Automated Description  Predicted to enable DNA binding activity and protein heterodimerization activity. Predicted to be a structural constituent of chromatin. Involved in mitotic sister chromatid segregation. Located in condensed chromosome and nucleus.
Biotype  SO:0001217 Genetic Position  III :0.495229 ±0.005206
Length (nt)  ? 1044

  Genes with expression altered >= 3-fold in dpy-10(e128) mutants. Data across the wild type series was analyzed using the Significance analysis of Microarrays (SAM) algorithm (to calculate the False Discovery Rate (FDR)). WBPaper00035873:dpy-10_regulated
  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
  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. WBPaper00045420:fertilization_downregulated_transcript
  Transcripts that showed significantly increased expression after animals were treated with 50uM Rifampicin and 250uM Allantoin from day 1 to day 3 adult hermaphradite. DESeq2(v1.14.1), fold change > 2, p-value < 0.05 WBPaper00055354:Rifampicin-Allantoin_upregulated
  Proteins interacting with NHR-49-GFP according to co-IP and LC-MS. N.A. WBPaper00064071:NHR-49_interacting
  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 L3 larva and Late reproduction stage (96 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_developing
  Transcripts that showed significantly increased expression in day 1 adult hermaphrodite comparing to in L4 larva fem-3(q20) animals. Fold change > 2, FDR < 0.05 WBPaper00064088:Day-1-adult_vs_L4_upregulated_fem-3(q20)

  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

  Genes with increased RNA expression after 24 hours rotenone treatment EdgeR provides statistical routines for determining differential expression in digital gene expression data using a model based on the negative binomial distribution. The resulting p-values were adjusted using the Benjamini and Hochbergs approach for controlling the false discovery rate (FDR). Transcripts with an adjusted p-value smaller 0.05 were assigned as differentially expressed. WBPaper00044426:rotenone_24h_upregulated
  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. WBPaper00037950:A-class-motor-neurons_L2-larva_expressed
Temprature shift to 28C for 24 hours. Transcripts that showed significantly decreased expression after animals were exposed to 28C temperature for 24 hours. Differentially expressed genes wereidentified using DESeq (v.1.18.0) by normalizing readsbased on the negative binomial distribution method andcomparing each HS timepoint to the 0-h control.

  Transcripts that showed significantly decreased expression in tetraploid N2 comparing to diploid N2 animals at L4 larva stage. DESeq2 R package (1.20.0), fold change > 2, and FDR < 0.05. WBPaper00066110:tetraploid_vs_diploid_downregulated
  Transcripts that showed significantly decreased expression in hpl-2(tm1489) comparing to in N2 animals. DESeq2, adjusted p-value < 0.05, log2 fold change > 2 or < -2. WBPaper00054493:hpl-2(tm1489)_downregulated

8 Expression Patterns

Remark Reporter Gene Primary Identifier Pattern Subcellular Localization
    Expr4208   GFP:CPAR-1 is not detectable in nuclei in the pachytene region of the gonad. GFP::CPAR-1 becomes visible in nuclei at the late pachytene/diplotene region and increases in intensity as the meiotic nuclei are cellularized to form oocytes. No GFP:CPAR-1 is detected in any of the dsRNA-injected gonads.
