WormBase Gene ID  ? WBGene00004914 Gene Name  snr-1
Sequence Name  ? Y116A8C.42 Brief Description  snr-1 encodes an ortholog of human small nuclear ribonucleoprotein Sm D3, a protein that forms part of a heptameric complex required for the biogenesis and function of the snRNPs that catalyze mRNA splicing; in combination with the gene that encodes the human Sm B ortholog (snr-2) snr-1 affects embryonic viability and the nuclear association and localization of P granules in embryos based on an RNAi assay, snr-1 also affects embryonic viability, growth, and fertility based on large-scale RNAi assays; snr-1 is expressed in embryos and is expressed in larvae and adults in muscles of the alimentary system, in body-wall muscle, in seam cells and other unidentified cells.
Organism  Caenorhabditis elegans Automated Description  Predicted to enable RNA binding activity. Predicted to be involved in spliceosomal snRNP assembly. Located in P granule. Expressed in germ line; gonad; head; and tail. Human ortholog(s) of this gene implicated in systemic lupus erythematosus. Is an ortholog of human SNRPD3 (small nuclear ribonucleoprotein D3 polypeptide).

  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.

    Expr3827 It was previously detected that SNR protein accumulate in the nuclei and cytoplasm of embryos and in the adult germline, using a pan-SNR antibody. Gene Catchr-derived GFP::SNR-1 fusion extends this result by showing that SNR-1 accumulates in the nuclei of many cell types throughout development. GFP::SNR-1 localizes to the nucleus.
    Expr2229 Expressed in embryos and adult gonads. Expression pattern in other tissue or life stages are not described in this paper. 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.
