	oocyte proteins identified by two or more unique peptides during proteomics study.	In the pooled data set, 1453 C. elegans proteins were identified with a probability >= 0.9 according to ProteinProphet, of which 1165 proteins were identified by more than one unique peptide.

	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.

	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

6 Expression Patterns

• Primary Identifier: Expr2034203
• 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: Expr1032446
• Pattern: Tiling arrays expression graphs

• Primary Identifier: Expr2229
• Pattern: Expressed in embryos and adult gonads. Expression pattern in other tissue or life stages are not described in this paper.
• Subcellular Localization: With most of these antibodies, staining was detected in nuclei and in the cytoplasm of many cell types, consistent with the localization of snRNPs in other organisms. Strikingly, Sm antibodies also stained cytoplasmic particles that colocalized with the P granule component PGL-1 within germ cells and their embryonic precursors. Sm staining was observed in nucleus-associated (perinuclear) P granules of adult germ cells and older embryos, as well as in cytoplasmic P granules of oocytes and early embryos. P granules were stained by several monoclonal and polyclonal antibodies that recognize different epitopes on Sm proteins . Furthermore, the staining of P granules by anti-Sm antibodies was greatly reduced after RNAi of Sm proteins but not after RNAi of RNA polymerase II. In addition, antibodies to U2AF65, another splicing factor, stained nuclei but did not stain P granules. Therefore, these results show that at least some Sm proteins are specific and constitutive components of P granules.
