WormMine: Gene WBGene00003783

• WormBase Gene ID: WBGene00003783
• Gene Name: nos-1
• Sequence Name: R03D7.7
• Brief Description: nos-1 encodes an putative RNA-binding protein that contains a zinc-binding motif homologous to that of Drosophila Nanos, a posterior-group protein required for embryonic patterning and primordial germ cell development; in C. elegans, NOS-1 is required redundantly with NOS-2, a second Nanos homolog, for maintenance of germ cell viability during postembryonic development and for preventing primordial germ cells from dividing in the absence of food; nos-1 mRNA is expressed dynamically in the embryo, with early expression seen throughout the embryo and later expression restricted solely to germline blastomeres; nos-1 mRNA becomes undetectable after the 200-cell stage, but reappears later at the 550-cell stage; NOS-1 protein is not detectable in germline blastomeres until the 550-cell stage, suggesting that NOS-1 might actually function zygotically in germline specification.
• Organism: Caenorhabditis elegans
• Automated Description: Predicted to enable mRNA binding activity. Involved in medium-term memory and short-term memory. Predicted to be located in perinuclear region of cytoplasm. Expressed in Z2 and Z3. Human ortholog(s) of this gene implicated in spermatogenic failure 12. Is an ortholog of human NANOS1 (nanos C2HC-type zinc finger 1); NANOS2 (nanos C2HC-type zinc finger 2); and NANOS3 (nanos C2HC-type zinc finger 3).

	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

Cuffcompare and Cuffdiff	WBPaper00056090:E.faecalis_downregulated_hpx-2(dg047)
	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.

7 Expression Patterns

• Primary Identifier: Expr1031769
• Pattern: Tiling arrays expression graphs

• Primary Identifier: Expr1158
• Pattern: maternal RNAs are preferentially maintained in germline blastomeres. nos-1 transcript is maintained in the germ lineage until approximately the 200-cell stage. nos-1 transcripts reappear in the primordial germ cells (PGCs) Z2 and Z3 in the 550-cell stage.

• Primary Identifier: Expr1160
• Remark: The specificity of antibody was confirmed by staining embryos deficient for NOS-1. Affinity-purified anti-NOS-1 antibody detected NOS-1 in nos-2(RNAi) embryos but not in nos-1(RNAi) and nos-1(gv5) embryos. NOS-1 and NOS-2 thus do not depend on each other for expression. To test whether NOS-1 is expressed zygotically, authors crossed nos-1(gv5) hermaphrodites (which express no NOS-1) to wild-type males and stained their progeny for NOS-1 protein. Detected NOS-1 expression in a pattern identical to that observed in embryos derived from wild-type hermaphrodites, confirming that NOS-1 expression is zygotic.
• Pattern: NOS-1 protein is expressed sequentially during embryogenesis. No NOS-1 protein was detected in pregastrulation embryos, even though nos-1 RNA is present in these stages. NOS-1 first appeared in Z2 and Z3 at the 550-cell stage and remained expressed in these cells until the end of embryogenesis.
