WormBase Gene ID  ? WBGene00000200 Gene Name  arx-2
Sequence Name  ? K07C5.1 Brief Description  arx-2 also called as Arp-2 encodes a subunit of the actin related protein of the conserved Arp2/3 complex, with 60% amino acid similarity with the homologous genes from human (OMIM: 604221); arx-2 is an essential gene as disruption in the expression by RNAi results in embryonic arrest due to ventral enclosure defects during morphogenesis; Arp2/3 depletion results in partial shrinking of the Ea/p apical surfaces and incomplete Ea/p cell internalization; WSP-1 activates Arp2/3 complex and their function in ventral enclosure is cell autonomous; Arp2/3 regulates some Apical Junction components in embryos and adults; Arp2/3 is required during intestinal morphogenesis for regulation of intestinal lumen width in embryos and apical F-actin accumulation during larval and adult growth. Mutations in arx-2 causes PDE axon guidance defects; arx-2 mutants affect PQR growth cone morphology and filopodia formation.
Organism  Caenorhabditis elegans Automated Description  Predicted to enable ATP binding activity and actin binding activity. Predicted to contribute to actin filament binding activity. Involved in Arp2/3 complex-mediated actin nucleation; embryonic morphogenesis; and epithelial cell migration. Predicted to be located in cell cortex. Predicted to be part of Arp2/3 protein complex. Expressed in Q cell; anchor cell; apoptotic cell; seam cell; and socket cell. Human ortholog(s) of this gene implicated in colorectal carcinoma and lung disease. Is an ortholog of human ACTR2 (actin related protein 2).

  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 that showed expression levels higher than the corresponding reference sample (L3/L4 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.

    Expr15181 Using ARX-2::GFP (an Arp2 homolog in C. elegans) knock-in animals, we showed that ARX-2::GFP fluorescence is specifically localized in the socket cells but is not detected in the cilia or the sheath cells, which is identical to the localization pattern of GFP::WSP-1A [Expr15180].

    Expr13650 ARX-2::GFP occupied 89% of the periphery of the leading edge.  
    Expr13399 In support of a role of ARX-2 in Q cell corpse clearance, ARX-2::GFP was recruited onto Q cell corpses at 37 ± 9 min (mean ± SD; n = 20) after Q cell birth, and the ARX-2::GFP rings lasted for 19 ± 9 min (n = 20). The corpse was completely degraded 34 ± 18 min (n = 20) after the disappearance of ARX-2::GFP, which suggests that ARX-2 may function during the engulfment of Q cell corpses but may not be involved in the final degradation inside the phagosome.

    Expr13408   SMN-1 expressed from the rescuing smn-1::mCherry transgene is seen in the nucleus and cytoplasm. In the cytoplasm, most SMN-1::mCherry is found at myofilaments in regularly spaced puncta. These puncta appear more ordered in adult muscle as compared with younger muscle. The SMN-1 expression pattern at muscle myofilaments resembles that of ARX-2::mCherry. To test whether ARX-2 and SMN-1 colocalize, we generated transgenic animals expressing both smn-1::GFP and arx-2::mCherry in muscle. SMN-1::GFP colocalizes with ARX-2::mCherry at the thin filaments. However, only SMN-1 is observed in the nucleus. We occasionally observed SMN-1::GFP and ARX-2::mCherry in peri-nuclear puncta. We conclude that SMN-1 and ARX-2 colocalize at muscle myofilaments adjacent to elongated mitochondrial tubules.
