WormMine: Gene WBGene00006748

• WormBase Gene ID: WBGene00006748
• Gene Name: unc-8
• Sequence Name: R13A1.4
• Brief Description: unc-8 encodes an amiloride-sensitive DEG/ENaC cation-selective channel subunit orthologous to human ENaCB (OMIM:600760, associated with Liddle syndrome, an autosomal dominant form of hypertension); UNC-8 is predicted to function as part of a mechanically gated channel that responds to stretch, and is required for modulating the sinusoidal body wave that is characteristic of C. elegans locomotion; unc-8 interacts genetically with unc-1 and unc-24, which encode stomatin-like proteins, and with mec-6, which encodes a paraoxonase; UNC-8 is expressed in motor neurons, sensory neurons, and interneurons in the nerve ring; UNC-8 may form a channel with the degenerin DEL-1, with which it is coexpressed in ventral cord motor neurons.
• Organism: Caenorhabditis elegans
• Automated Description: Predicted to enable ligand-gated sodium channel activity. Involved in locomotion and neuron remodeling. Located in neuronal cell body. Expressed in neurons. Human ortholog(s) of this gene implicated in bronchiectasis (multiple) and renal tubular transport disease (multiple). Is an ortholog of human SCNN1B (sodium channel epithelial 1 subunit beta); SCNN1D (sodium channel epithelial 1 subunit delta); and SCNN1G (sodium channel epithelial 1 subunit gamma).

	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.

12 Expression Patterns

• Primary Identifier: Expr15442

• Primary Identifier: Expr7928
• Remark: Picture: Figure 2. Reporter gene fusion type not specified.
• Pattern: Expressed in more than 10 neurons but not ASE.

• Primary Identifier: Expr1615
• Remark: Reporter gene fusion type not specified.
• Reporter Gene: pR13A14lacZ expression pattern were also characterized in a strain in which the reporter construct was stably integrated into the genome (ZB167), which gave results consistent with those observed for mosaic animals. An identical expression profile was observed when a second fusion, including 2.5 kb upstream of the predicted initiation codon, was assayed.
• Pattern: pR13A14lacZ activity is apparent in the embryo and is first detected during the 3-fold stage, about 300 min prior to hatching. This staining is likely to occur in the embryonically derived DA, DB, and/or DD motor neurons. Beta-galactosidase activity is observed in additional neurons later in development and peaks during the L2 stage when intense staining of sensory neurons, interneurons in the nerve ring, and motor neurons in the ventral nerve cord are apparent. Strong staining persists into adulthood. Among the neurons that express pR13A14lacZ are the ASH and FLP sensory neurons, the PVM touch neuron, the PVC, AVB, AVA, and AVD command interneurons, and the PDA, PDB, DA, DB, DD, VA, VB, and VD classes of motor neurons. Additional neurons situated either within or in the vicinity of the nerve ring express the R13A1_4 reporter gene. In summary, R13A1_4 expression is neuron specific and restricted to about 45 cells.

• Primary Identifier: Expr2036054
• Pattern: Single cell embryonic expression. Only cell types with an expression fraction of greater 0.2 of the maximum expressed fraction are labeled (Full data can be downloaded from http://caltech.wormbase.org/pub/wormbase/datasets-published/packer2019/). The colors represent the broad cell class to which the cell type has been assigned. The size of the point is proportional to the log2 of the numbers of cells in the dataset of that cell type.

• Subcellular Localization: DEL-1 and UNC-8 colocalize at puncta along the PVD dendrites.

• Primary Identifier: Expr3408
• Subcellular Localization: The UNC-8 protein was detected in lipid rafts in wild-type animals. However, UNC-8 also were localized to the higher density membrane pellet. In unc-8(0) animals, no UNC-8 was detectable in the fractions that contained rafts. In addition, UNC-8 protein was not detected in lipid raft preparations from unc-1(0) animals.
