WormBase Gene ID  ? WBGene00015267 Gene Name  chin-1
Sequence Name  ? BE0003N10.2 Brief Description  chin-1 encodes a putative GTPase activating protein (GAP) and is orthologous to vertebrate chimaerins; chin-1 negatively regulates CDC-42 during asymmetric division in the embryo; chin-1 restricts both the spatial extent of CDC-42 expression and the recruitment of NMY-2 during the phase in which polarity is maintained by CDC-42; chin-1 is also required for viability and normal gonad morphology; CHIN-1 is expressed in the cytoplasm and the cortical region; CHIN-1 expression is stabilized by PAR-2.
Organism  Caenorhabditis elegans Automated Description  Predicted to enable GTPase activator activity. Involved in protein localization. Located in cell cortex. Human ortholog(s) of this gene implicated in Duane retraction syndrome 2. Is an ortholog of human CHN1 (chimerin 1).
Biotype  SO:0001217 Genetic Position  III :-24.785 ±0.003603

Regulated By Treatment Description Algorithm Primary Identifier
  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 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
  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:AVE-neuron_L1-larva_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

Picture: Figure 5A, Movie 13.   Expr8862   GFP::CHIN-1, expressed under germline regulatory control, localized to the centrosomes, pronuclei, central spindle and cell cortex in the early embryo . This reporter strain exhibited no cortical enrichment during Phase I but was recruited to the posterior cortex both in a diffuse pattern and in discrete puncta Phase II (23/23 embryos). These puncta flowed into the ingressing cleavage furrow during Phase III. In older embryos, signal was observed at cell borders, nuclei and centrosomes.
Picture: Figure 5C.   Expr8863   The localization of endogenous CHIN-1 by immunolocalization recapitulates the cytoplasmic and cortical localization of the transgene with no cortical localization during Phase I (0/4 embryos), posterior cortical localization in Phase II (6/7 embryos) and posterior cortical localization of P 1 cells in late prophase and anaphase (5/5 embryos).
