WormBase Gene ID  ? WBGene00008570 Gene Name  kcnl-2
Sequence Name  ? F08A10.1 Brief Description  kcnl-2 encodes multiple isoforms of a small conductance, calcium-activated potassium (K+) channel homologous to mammalian SK channels; KCNL-2 activity is required for regulation of the rate of egg laying: loss-of-function kcnl-2 mutations result in an egg-laying defective phenotype, while kcnl-2 overexpression results in hyperactive egg-laying behavior; KCNL-2 GFP reporter fusion proteins are expressed in the nervous system, including head neurons, the nerve ring, ventral nerve cord motor neurons, the dorsal cord, tail ganglia, and the VC4 and VC5 neurons of the egg-laying apparatus; kcnl-2 expression is also seen in the vulval muscles.
Organism  Caenorhabditis elegans Automated Description  Predicted to enable calmodulin binding activity and small conductance calcium-activated potassium channel activity. Involved in positive regulation of egg-laying behavior. Located in neuron projection. Expressed in nervous system; seam cell; and vulval muscle. Human ortholog(s) of this gene implicated in dystonia and paranoid schizophrenia. Is an ortholog of human KCNN1 (potassium calcium-activated channel subfamily N member 1).

  Transcripts that showed significantly increased expression in L1 neural cells comparing to in adult neural cells. DESeq2 (v1.18.1) fold change > 2, P-adj<0.05, using BenjaminiHochberg correction. WBPaper00060811:L1_vs_adult_upregulated_neural
  Transcripts of coding genes that showed significantly decreased expression in muscle. DESeq2 (version 1.24.0). Transcripts with a false-discovery rate adjusted p-value less than 0.05 were considered significantly differentially expressed. WBPaper00062325:muscle_depleted_coding-RNA
  Transcripts expressed in neuronal cells, by analyzingfluorescence-activated cell sorted (FACS) neurons. DESeq. False discovry rate (FDR) < 0.1. WBPaper00048988:neuron_expressed
  Genes significantly enriched (> 2x, FDR < 5%) in a particular cell-type versus a reference sample of all cells at the same stage. 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.

  Genes that showed significantly increased expression in daf-2(e1370);hel-1(gk148684) comparing to in hel-1(gk148684) To identify DEGs, Students t test and the log2 median ratio test were performed to compute t values and median ratios for all the annotated genes. The adjusted P values from each test were computed using an empirical distribution of the null hypothesis, which was obtained from random permutations of the samples. Finally, the adjusted P values from the individual tests were combined to compute the overall P values using Stouffers method , and genes with overall P < 0.05 and fold change > 1.5 were selected as DEGs.

9 Expression Patterns

Remark Reporter Gene Primary Identifier Pattern Subcellular Localization
    Expr1033734 Tiling arrays expression graphs  
    Expr11268 Four constructs were made where GFP was fused to either initiation site or stop codon in order to determine if the splice variants are differentially expressed. Expression of the transformation vectors was driven under 1,951 bp of the KCNL-2 endogenous promoter. Confocal fluorescent imaging of transgenic lines expressing these constructs in the N2 background showed a neuronal expression pattern. expression of KCNL-2 when tagged at the latter stop codon (pkcnl-2kcnl-2(taa2)::gfp) was detected in head neurons, the nerve ring (NR), motor neurons of the ventral nerve cord (VNC), the dorsal cord (DC) and tail ganglia. The pkcnl-2kcnl-2(taa2)::gfp construct was expressed in many neuronal processes innervating the vulva while pkcnl-2gfp::(atg2)kcnl-2 shows expression in the VC4 and VC5 neurons of the egg-laying apparatus in addition to other neuronal processes innervating the vulva. The authors made two additional constructs to drive GFP expression under the KCNL-2 promoter to aid in determining the complete expression profile of KCNL-2 that may be masked in transgenic lines that express GFP-tagged KCNL-2.The first construct, pkcnl-2(atg1) gfp, encompassed the coding sequence of GFP which was expressed downstream of the promoter of KCNL-2 (1,951 bp upstream of atg1). The second construct, pkcnl-2(atg2) gfp, expressed GFP at the second initiation site where the coding sequences for kcnl-2-b and -c were deleted. pkcnl-2(atg1) gfp showed a neuronal expression profile with additional GFP-expression in the vulval muscles. pkcnl-2(atg2) gfp showed a strict neuronal expression profile that complemented the expression profile of the pkcnl-2kcnl-2::gfp constructs. pkcnl-2(atg2) gfp readily labels the VC4 and VC5 neurons and displays a highly innervated vulva, a feature that is lacking in the expression profile of pkcnl-2(atg1) gfp. Ultimately, since both pkcnl-2(atg1) gfp and pkcnl-2(atg2) gfp are expressed in different neurons, this suggests that the various isoforms of KCNL-2 may have differing neuronal expression profiles.
