WormBase Gene ID  ? WBGene00018572 Gene Name  lin-42
Sequence Name  ? F47F6.1 Brief Description  lin-42 encodes three PAS domain-containing proteins orthologous to insect and vertebrate Period proteins that function in regulation of circadian rhythms; during larval development, lin-42 functions in the heterochronic pathway to regulate developmental switches that occurs in multiple tissues, including the hypodermis, gonad, sex myoblasts, and vulva; genetic analysis suggests that, in the hypodermis, lin-42 acts downstream of lin-46 and in the hypodermis and gonad, in parallel to daf-12 and upstream of lin-29; lin-42 mRNA levels oscillate during larval development with peak levels seen during intermolts and low levels seen during ecdysis and after the L4-to-adult molt; LIN-42 protein appears to be a widely expressed nuclear protein whose levels also fluctuate during larval stages, with peak protein typically seen towards the latter half of each larval stage in a cell type-specific manner, and then disappearing during each successive molt; in addition to three PAS domain-containing proteins, lin-42 also encodes a protein that lacks the PAS domain; transformation rescue experiments indicate that the LIN-42 isoform lacking the PAS domain is sufficient for rescue when present in multiple copies.
Organism  Caenorhabditis elegans Automated Description  Enables RNA polymerase II-specific DNA-binding transcription factor binding activity. Involved in negative regulation of dauer larval development; negative regulation of miRNA transcription; and regulation of development, heterochronic. Located in cytoplasm and nucleus. Expressed in head; hyp7 syncytium; and pharyngeal muscle cell. Human ortholog(s) of this gene implicated in advanced sleep phase syndrome 1 and cocaine dependence. Is an ortholog of human PER1 (period circadian regulator 1) and PER2 (period circadian regulator 2).

  Coexpression clique No. 60, 176662_at-Y53F4B.16, on the genome-wide coexpression clique map for the nematode GPL200 platform. All available microarray datasets for the GPL200 platform (Affymetrix C. elegans Genome Array) were obtained from the GEO repository. This included 2243 individual microarray experiments. These were normalized against each other with the software RMAexpress (Bolstad, 2014). Based on these normalized values, Pearsons correlation coefficients were obtained for each probe-probe pair of the 22,620 probes represented on this array type. The resulting list of correlation coefficients was then ranked to generate the ranked coexpression database with information on each probe represented on the GPL200 platform.

  Genes with expression level regulated by genotype (N2 vs CB4856) and age at L3 larva and Late reproduction stage (96 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_developing

Remark Reporter Gene Primary Identifier Pattern Subcellular Localization
    Expr4568   These antibodies reveal that LIN-42C/D is nuclear and broadly expressed.
    Expr2871 The mRNAs for lin-42, nhr-23, and nhr-41a exhibit a low-high (peak)-low profile during the L1 intermolt that is precisely reiterated at later stages. The mRNAs for nhr-25a, nhr-25b, and nhr-41b have a high-low-high (peak) expression profile during the L1 stage (and into early L2) that is also reiterated. nhr-25a and nhr-41b also show a downward trend in baseline expression as development proceeds. For all six mRNAs, there are peaks of expression that occur at precise intervals relative to the molt at all larval stages: nhr-25b and nhr-41b peak at the beginning of the intermolt; nhr-23 peaks at mid-intermolt, slightly preceding the intermolt peak in lin-42 expression; and nhr-25a and nhr-41a peak at the time the larval molts occur. Two mRNAs, nhr-6 and nhr-85a, show a more irregular expression pattern with respect to the molt; however, it should be noted that nhr-6 mRNA has consistent relatively lower expression values at the times the molt takes place. nhr-67 also does not display a reiterated, oscillating expression pattern, although two early peaks are observed at the end of the L1 stage and at the beginning of L2.

  [lin-42ap::gfp-pest] transcriptional fusion. The start codon of lin-42a and 3,043 bps of upstream sequence were fused with gfp-pest. --precise ends. Expr9861 GFP expressed from the lin-42a promoter was robustly expressed in the pharyngeal myoepithelium midway through the L1 stage and continuously thereafter. The lin-42a reporter was also expressed in hyp7 and the lateral seam cells of late L1-stage larvae undergoing the first molt. Expression of the lin-42a reporter in the hypodermis was detected later in the L1 stage than expression of the lin-42b reporter. Fluorescence from the lin-42a reporter also persisted through ecdysis, whereas fluorescence from the lin-42b reporter dissipated during lethargus. To fully define the cyclical expression pattern of the lin-42ap::gfp-pest fusion gene, we measured the relative intensity of the associated fluorescence in the hypodermis throughout larval development. The intensity of fluorescence repeatedly increased 2- to 10-fold during the molts and dropped to background levels early in the next life stage.  
This information was extracted from published material (Archana Sharma-Oates, Andrew Mounsey and Ian A. Hope).   Expr691 First detected in late embryonic stage and continues to be detected through to adulthood. Intensity is higher in animals undergoing ecdysis. Subcellular accumulation generally enriched in nuclei relative to cytoplasm. Cytoplasmic signal is enhanced in lateral seam cells during the molt periods. There is a period of cytokinesis where LIN-42::GFP is not observed. L3 molt: Higher intensity in seam cells, but most intense in V1.pppp. Cells that stain at this stage: H1.aa, V4.papp, H1.app, V5.pppp, H2.ppp V6.papp, V2.papp V6.pppp, V2.pppp, V3.papp, V3.pppp, V4.pppp. L4 molt higher intensity of staining observed in the cytoplasm of seam cell. LIN-42::GFP is present in lateral hypodermis, hyp7 synctium which includes main body hypodermis and head and tail hypodermal cells. Expressed in cytoplasm of seam cell during L4 molt.

    Expr12252 Plin-42a::GFP-pest and Plin- 42b::mCherry-pest reporters displayed highly pulsatile expression during the L1 stage with initiation and termination of expression at 12 and 28 hours post L1 arrest, respectively. In addition, Plin-42a::GFP-pest expression peaks at 16 hrs, immediately preceding the expression of the Pmir::GFPpest reporters, while the peak of Plin-42b::mCherry-pest expression occurs at 20 hrs. Detailed analysis of individual L3-to-adult animals indicates that Plin-42a::GFP-pest expression displays a temporal expression pattern that is highly similar to Plin-4::GFP-pest and Plet-7::GFP-pest expression. Specifically, in all three reporters, GFP-pest expression diminishes prior to L3 ecdysis, resumes prior to the L4 lethargus period, and terminates immediately after L4 ecdysis.  
This information was extracted from published material (Archana Sharma-Oates, Andrew Mounsey and Ian A. Hope).   Expr693 mRNA level is lower in animals undergoing ecdysis compared to levels in intermolt animals.  
This information was extracted from published material (Archana Sharma-Oates, Andrew Mounsey and Ian A.

After L4 to adult molt mRNA levels remain low.
