WormMine: Gene WBGene00006353

• WormBase Gene ID: WBGene00006353
• Gene Name: sur-7
• Sequence Name: F01G12.2
• Brief Description: sur-7 encodes a slightly divergent member of the cation diffusion facilitator (CDF) family of transmembrane proteins; two other elegans CDF proteins, cdf-1 and cdf-2 have also been identified; CDF proteins regulate the transport of heavy metal ions like zinc; sur-7 loss of function mutants are hypersensitive to high zinc ion concentrations; sur-7 positively regulates Ras-mediated signaling during vulval development, most likely by promoting the cytoplasmic efflux of zinc ions, as cytosolic zinc inhibits Ras signaling; sur-7 localizes to the endoplasmic reticulum; the sub-cellular localization of sur-7 to the endoplasmic reticulum suggests that sur-7 may sequester zinc ions in cellular organelles.
• Organism: Caenorhabditis elegans
• Automated Description: Involved in several processes, including cellular response to zinc ion; muscle cell cellular homeostasis; and positive regulation of Ras protein signal transduction. Located in endoplasmic reticulum membrane. Expressed in several structures, including hypodermis; muscle cell; pharynx; tail; and vulva.

	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 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

	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.

	Genes that showed expression levels higher than the corresponding reference sample (L3/L4 all cell 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.

• Primary Identifier: Expr2035274
• 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: Expr2883
• Reporter Gene: The sur-7HGFP construct is functional since the expression of this construct rescues sur-7(ku119);let-60(n1046).
• Pattern: SUR-7HGFP was expressed in most tissues with the notable exception of intestinal cells. Under a UV-light dissecting microscope, GFP was seen to be strongly expressed in the pharynx, some tail cells and the vulva. Under higher magnification, GFP was observed in many if not all neurons, muscles and hypodermal cells.
• Subcellular Localization: SUR-7HGFP was not localized to the plasma membrane, as was the case for a CDF-1HGFP construct, but was enriched at the nuclear periphery and throughout the cytoplasm in a fenestrated pattern. This localization is endoplasmic reticular for two reasons. First, this expression pattern is indistinguishable from that of a C. elegans YFPHTRAM construct (TRAM is an endoplosmic recticulum (ER) transmembrane protein). Secondly, several CDF family members are known to be ER localized.
