WormMine: Gene WBGene00004795

• WormBase Gene ID: WBGene00004795
• Gene Name: sid-1
• Sequence Name: C04F5.1
• Brief Description: sid-1 encodes a dsRNA channel with conserved human (OMIM:606816) and mouse homologs; SID-1 functions to enable passive (ATP-independent) uptake of double-stranded RNA (dsRNA) and is required cell autonomously for systemic RNA interference (RNAi) and for efficient reduction of multicopy transgene expression (repeat-induced silencing); SID-1 is not, however, required for export of RNA silencing from C. elegans tissues; a SID-1::GFP fusion is enriched at cellular membranes of most nonneuronal cells from late embryogenesis through adulthood with highest levels detected in cells exposed to the environment; SID-1 extracellular domain (ECD) selectively binds long double-stranded RNA (dsRNA) and the binding affinity is related to RNA transport efficiency.
• Organism: Caenorhabditis elegans
• Automated Description: Enables RNA transmembrane transporter activity and double-stranded RNA binding activity. Involved in dsRNA transport and regulatory ncRNA-mediated post-transcriptional gene silencing. Located in plasma membrane. Expressed in several structures, including pharynx.
• Biotype: SO:0001217

	mRNAs that showed decreased expression in 1 cell mebryo comparing to in oocyte, according to RNAseq analysis.	Gaussian error propagation. As cutoff for the up-regulated genes authors used log2 fold change > 1 and P < 0.05 and as cutoff for the down-regulated genes authors used log2 fold change < -1 and P < 0.05.

Osmotic stress	Transcripts that showed significantly altered expression with 500 mM salt (NaCl) vs 100 mM salt when food was present	DESeq(version 1.10.1), FDR < 0.05.	WBPaper00050726:OsmoticStress_regulated_Food

	Maternal class (M): genes that are called present in at least one of the three PC6 replicates.	A modified Welch F statistic was used for ANOVA. For each gene, regressed error estimates were substituted for observed error estimates. The substitution is justified by the lack of consistency among the most and least variable genes at each time point. Regressed error estimates were abundance-dependent pooled error estimates that represented a median error estimate from a window of genes of similar abundance to the gene of interest. A randomization test was used to compute the probability Pg of the observed F statistic for gene g under the null hypothesis that developmental time had no effect on expression. P-values were not corrected for multiple testing.	[cgc5767]:expression_class_M
	Genes with expression level regulated by genotype (N2 vs CB4856) and age at old adults stage (214 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_aging

	Strictly maternal class (SM): genes that are the subset of maternal genes that are not also classified as embryonic.	A modified Welch F statistic was used for ANOVA. For each gene, regressed error estimates were substituted for observed error estimates. The substitution is justified by the lack of consistency among the most and least variable genes at each time point. Regressed error estimates were abundance-dependent pooled error estimates that represented a median error estimate from a window of genes of similar abundance to the gene of interest. A randomization test was used to compute the probability Pg of the observed F statistic for gene g under the null hypothesis that developmental time had no effect on expression. P-values were not corrected for multiple testing.	[cgc5767]:expression_class_SM

8 Expression Patterns

• Primary Identifier: Expr2034047
• 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. Interactive visualizations are available as a web app (https://cello.shinyapps.io/celegans/) and can also be installed as an R package (https://github.com/qinzhu/VisCello.celegans).

• Primary Identifier: Expr11213
• Pattern: The sid-1 promoter appears to be most active in the pharynx.

• Primary Identifier: Expr1032379
• Pattern: Tiling arrays expression graphs

• Primary Identifier: Expr13321
• Pattern: The majority of sid-1 mRNA expression is confined to the germline in wild-type C. elegans.

• Primary Identifier: Expr1867
• Pattern: A transgene that includes only the sid-1 promoter region fused to GFP (sid-1 pro::GFP), is expressed in late embryos and continues to be detected in nearly all nonneuronal cell types through adulthood. The highest levels of GFP expression in the adult are in the cells and tissues in direct contact with the environment. These environment-exposed cells also show expression of a transgene construct in which GFP was fused to the COOH-terminus of full-length SID-1 (sid-1::C-GFP). This construct was capable of rescuing sid-1(qt2) animals, suggesting that localization of this reporter is representative of SID-1 localization. Expression of SID-1::C-GFP was only seen in these environment exposed cells, perhaps because of the significantly lower expression of the translational reporter relative to the transcriptional reporter.
• Subcellular Localization: In addition to cytoplasmic expression, significant enrichment of subcellular localization of SID-1::C-GFP was seen at the cell periphery.
