WormBase Gene ID  ? WBGene00018285 Gene Name  smk-1
Sequence Name  ? F41E6.4 Brief Description  smk-1 encodes a novel, evolutionarily conserved protein that is orthologous to the mammalian and Dictyostelium discoideum SMEK (suppressor of MEK null) proteins; smk-1 activity is essential for several aspects of DAF-16-mediated longevity namely, the defense response to pathogenic bacteria and increased resistance to oxidative and UV-induced damage; in regulating DAF-16 activity, SMK-1 appears to act by affecting the transcription of DAF-16 target genes, such as sod-3, ctl-1, and lys-8; SMK-1 is present in the nucleus of intestinal cells, many head and tail neurons, and some hypodermal cells throughout development.
Organism  Caenorhabditis elegans Automated Description  Predicted to enable protein phosphatase activator activity. Involved in negative regulation of mitotic DNA damage checkpoint; response to radiation; and response to stress. Located in nucleus. Expressed in hypodermis; intestine; and tail. Is an ortholog of human PPP4R3A (protein phosphatase 4 regulatory subunit 3A) and PPP4R3B (protein phosphatase 4 regulatory subunit 3B).
Biotype  SO:0001217 Genetic Position  V :1.48475 ±0.002222

  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

  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.

The GFP signal was reduced upon treatment with smk-1 RNAi, and Western blot analysis showed that SMK-1 protein levels were reduced upon smk-1 RNAi treatment.   Expr3839 Using a gfp-tagged smk-1 cDNA construct under the control of the endogenous smk-1 promoter to create a stable transgenic line, strong nuclear localization of SMK-1-GFP was observed in intestinal cells. GFP fluorescence was also detected in the nuclei of several hypodermal cells and in many neurons in the head and tail. Expressed in nuclei.
    Expr3840 Endogenous SMK-1 could be detected in the nuclei of intestinal cells, hypodermal cells, and head and tail neurons by staining with affinity-purified SMK-1 antibodies. Examination of SMK-1-GFP at different larval stages revealed patterns of consistent nuclear localization throughout development. Expressed in nuclei.
