WormBase Gene ID  ? WBGene00003558 Gene Name  nca-2
Sequence Name  ? C27F2.2 Brief Description  nca-2 encodes, along with unc-77, an alpha-1 subunit of a voltage-insensitive cation leak channel related to Drosophila narrow abdomen and the vertebrate Vgcnl1/NALCN proteins; nca-2 functions redundantly with unc-77 to transmit depolarization signals from neuronal cell bodies to axons, thus regulating presynaptic activation; nca-2 and unc-77 are also required for normal locomotion and the response to specific volatile anesthetics; in neuronal activity, unc-77 and nca-2 function in the same pathway as unc-79, which encodes a conserved novel protein that positively regulates levels of UNC-77 and NCA-2 protein; in turn, unc-77 and nca-2 likely regulates levels of UNC-79 and UNC-80, an additional novel protein that appears to function in the same pathway to regulate synaptic activity; nca-2::gfp reporters are expressed in the nervous system in a few pharyngeal neurons, many nerve ring interneurons, most ventral nerve motor cord neurons, and in neurons and muscles in the tail; diffuse expression is also seen in vulval muscles and the intestine.
Organism  Caenorhabditis elegans Automated Description  Predicted to enable monoatomic cation channel activity. Involved in positive regulation of GABAergic synaptic transmission; positive regulation of cholinergic synaptic transmission; and positive regulation of locomotion. Predicted to be located in plasma membrane. Expressed in several structures, including intestine; pharyngeal neurons; and somatic nervous system. Human ortholog(s) of this gene implicated in congenital limbs-face contractures-hypotonia-developmental delay syndrome. Is an ortholog of human NALCN (sodium leak channel, non-selective).

  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 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.

  Genes with expression level regulated by genotype (N2 vs CB4856) 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_regulated_developing
