WormBase Gene ID  ? WBGene00001309 Gene Name  emr-1
Sequence Name  ? M01D7.6 Brief Description  emr-1 gene encodes a homolog of the human integral nuclear membrane protein emerin ; EMR-1 belongs to a family of proteins sharing the LEM-domain (LAP2-Emerin-MAN1 domain) that are generally conserved in metazoa and bind to lamin; EMR-1, along with another LEM-domain protein, LEM-2 is required for larval development, normal life-span, nuclear envelope and chromatin organization, chromosome segregation and cell division; emr-1 is also required for smooth muscle activity; emr-1 negatively regulates pha-4, the transcription factor required for pharynx identity; EMR-1 protein is found in the nuclear envelopes of all cell types except sperm and at all life stages; EMR-1 binds to lamin/LMN-1; emr-1 mutations also exhibit weak hypersensitivity to DNA damage.
Organism  Caenorhabditis elegans Automated Description  Enables lamin binding activity. Involved in several processes, including mitotic cytokinesis; nuclear envelope organization; and response to X-ray. Located in nuclear inner membrane. Used to study Emery-Dreifuss muscular dystrophy. Is an ortholog of human LEMD1 (LEM domain containing 1).

  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 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.

No detailed description on cellular localization.   Expr1068   During interphase, endogenous Ce-emerin localized at the nuclear envelope and colocalized with lamins (Ce-MAN1 protein also colocalized with the lamina). nuclear rim staining by Ce-emerin persisted during prophase, metaphase, and early anaphase.
Previous studies showed that Ce-emerin, like its human ortholog, colocalizes with Ce-lamin, requires Ce-lamin for its inner nuclear membrane localization and co-immunoprecipitates with Ce-lamin.   Expr2365   This experiment confirmed that Ce-emerin is associated with the peripheral chromatin.

    Expr11865   Ce-emerin was detected at the nuclear envelope in all embryonic cells, and was detected in all cells examined throughout larval development and in adult N2 hermaphrodites, including the gonad, with one possible exception. Ce-emerin was not detected in cells undergoing spermiogenesis that had reached the stage of having condensed chromatin. However, we could not definitively conclude that emerin was absent from sperm, because sperm lack Ce-lamin (Liu et al., 2000) and therefore had no positive control for antibody access into these cells during staining. Nevertheless, the nearly ubiquitous positive staining seen for Ce-emerin throughout development and in adult animals was similar to that seen for human emerin, which is found in most cell types examined (Manilal et al., 1999).
