WormBase Gene ID  ? WBGene00004130 Gene Name  ketn-1
Sequence Name  ? F54E2.3 Brief Description  ketn-1 encodes an ortholog of kettin (in D. melanogaster, SALLIMUS), an invertebrate isoform or paralog of titin; ketn-1 is transcriptionally upregulated two-fold by hypoxia, requires both HIF-1 and VHL-1 for this induction, and contains three predicted HIF-1 binding sites in its predicted 5' regulatory region; ketn-1's induction by hypoxia correlates with upregulation of other genes required for collagen synthesis (phy-2 and bli-3), encoding lectin domains (C31G12.2, F35D11.10, and F47C12.2), or encoding a chitin-binding protein (K04H4.2); ketn-1 is expressed in the reproductive system and several muscle types (body wall, vulval, anal depressor, and probably pharyngeal); KETN-1 colocalizes with actin to I-bands in muscle cells, but more narrowly than actin, and falls into repeated blocks alternating with non-overlapping blocks of DEB-1/vinculin.
Organism  Caenorhabditis elegans Automated Description  Predicted to enable actin binding activity. Located in I band. Expressed in anal depressor muscle; body wall musculature; male gonad; and pharyngeal muscle cell.
Biotype  SO:0001217 Genetic Position  V :-13.0693 ±0.013103

  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
  TGF- Dauer pathway adult transcriptional targets. Results obtained by comparing the microarray results of the dauer-constitutive mutants daf-7(e1372), daf-7(m62), and daf-1(m40) with dauer-defective mutants daf-3(mgDf90), daf-5(e1386), and daf-7(e1372);daf-3(mgDf90) double mutants at the permissive temperature, 20C, on the first day of adulthood. SAM WBPaper00031040:TGF-beta_adult_upregulated
  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.

Picture: Figure 3.   Expr7982   Authors reexamined intracellular localization of Ce-kettin by double or triple staining with other cytoskeletal markers and found that it localized to a portion, not the entire length, of the I-bands. Triple staining of body wall muscle for actin (thin filaments), Ce-kettin (MH44), and myosin heavy chain (thick filaments) confirmed that Ce-kettin is associated with the thin filaments. However, Ce-kettin localized to a ladder-like pattern and its localization was limited to a narrow region in the middle of the bands of actin. Triple staining for actin, Ce-kettin, and vinculin (dense bodies) showed that Ce-kettin has some overlap with vinculin, but the center of the dense bodies was devoid of Ce-kettin. In addition, comparison with the location of tropomyosin showed that tropomyosin localized to the outer region on the thin filaments with minimal overlap with Ce-kettin. These results indicate that Ce-kettin is associated with a portion of the thin filaments near the dense bodies.

This pattern is inconsistent with the report by Kolmerer and colleagues that a monoclonal antibody against insect kettin recognizes the dense bodies in the C. elegans body wall muscle. Furthermore, the MH44 staining significantly extends into the I-bands towards the A-bands, whereas kettin in insects or crayfish localizes in or near the Z-discs. Therefore, further studies on the localization of C. elegans kettin are needed to determine if these discrepancies are due to different epitopes recognized by the antibodies or inherent unique characteristics of C. elegans kettin that might be adapted to the obliquely striated muscle.   Expr3812   Kettin co-localized with actin in a ladder-like pattern, but the width of the staining was narrower than the actin bands. Vinculin, a component of the dense bodies, localized to the spots where the kettin staining was very weak or absent. Therefore, kettin is associated with a portion of the thin filaments near the dense bodies, which are equivalent to the Z-discs in cross-striated muscles.
