WormBase Gene ID  ? WBGene00000106 Gene Name  alg-2
Sequence Name  ? T07D3.7 Brief Description  alg-2 encodes a PAZ and PIWI-domain containing protein that is a member of the highly conserved eukaryotic RDE-1/AGO1/PIWI family of proteins that regulate posttranscriptional gene silencing (PTGS); ALG-2 functions with ALG-1 to control specific developmental timing events by positively regulating expression of small temporal RNAs (stRNAs) encoded by lin-4 and let-7; ALG-2 and ALG-1 are also required for RNAi in the germ line, although they are not required for RNAi in the soma; ALG-2 is expressed in nearly all cells from embryogenesis through adulthood and localizes to the cytoplasm.
Organism  Caenorhabditis elegans Automated Description  Enables RNA binding activity and RNA endonuclease activity. Involved in embryo development; nematode larval development; and regulatory ncRNA-mediated gene silencing. Located in cytoplasm. Part of RISC complex. Expressed in several structures, including gonad; hypodermis; neurons; somatic cell; and ventral nerve cord. Human ortholog(s) of this gene implicated in alcohol dependence and glaucoma. Is an ortholog of human AGO2 (argonaute RISC catalytic component 2).

  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. WBPaper00045420:fertilization_downregulated_transcript
  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.

  Genes that showed expression levels higher than the corresponding reference sample (L2 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.

Reporter gene fusion type not specified.   Expr4610 Expressed in the cytoplasm from early embryogenesis to adulthood in most, if not all, cells in C. elegans. There is no clear difference in the expression patterns of alg-1 and alg-2.  
    Expr2009289 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.

    Expr1030055 Tiling arrays expression graphs  
    Expr16402    
    Expr10011 ALG-2 was predominantly expressed in subsets of neurons in the head ganglia. Cells in the tail also displayed specific expression. Expression was seen in vulva, seam cells, ventral nerve chord and somatic gonad. Examination of the ALG-2 expression during larval development did not reveal differences in expression during the four larval stages and adults. During embryogenesis ALG-2 started to be expressed from pre-morphogenetic embryonic stages.

    Expr13806 ALG-1 and ALG-2 were expressed in most somatic cells but exhibited some tissue specificity in the head region. Pharyngeal cells predominantly expressed GFP::ALG-1, while certain head neurons adjacent to the pharynx were enriched for RFP::ALG-2. Consistent with the Western blot results, there was a global decline in expression of GFP:: ALG-1 but not RFP::ALG-2 as the animals aged.
