WormBase Gene ID  ? WBGene00004105 Gene Name  szy-20
Sequence Name  ? C18E9.3 Brief Description  szy-20 encodes a conserved RNA binding protein; szy-20 functions to negativelyregulate centrosome size, duplication, and microtubule-nucleating capacity by limiting the amount of centriolar and pericentriolar material, such as gamma-tubulin and ZYG-1, SPD-2, and SPD-5, at the centrosomes; SZY-20 also plays a role in cytokinesis, centrosome attachment to the nucleus, mitotic metaphase spindle length, polar body extrusion, pronuclear rotation,and possibly block to polyspermy; SZY-20 localizes to centrosomes as well as to nucleoli during interphase, the surface of meiotic and mitotic chromosomes, and to small cytoplasmic foci; a GST::SZY-20 fusion protein binds polyuridine-coupled beads in vitro.
Organism  Caenorhabditis elegans Automated Description  Predicted to enable RNA binding activity. Involved in several processes, including negative regulation of protein localization to centrosome; positive regulation of fertilization; and regulation of cell cycle. Located in centrosome; cytoplasm; and nucleolus.
Biotype  SO:0001217 Genetic Position  II :0.938547 ±0.001569

  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

Picture: Fig 3.   Expr8947   In immunostained embryos, SZY-20 is found in small foci in the cytoplasm and at centrosomes where it coincides with GFP-SAS-4, a marker of centrioles. In addition, SZY-20 localizes to nucleoli during interphase and to the surface of chromosomes during meiosis and mitosis. RNAi of szy-20 significantly reduces staining of all structures, confirming the specificity of the antibody. SZY-20 is first detected at centrosomes during meiosis where it often appears as two distinct dots adjacent to the male pronucleus. While SZY-20 localizes to the centrosome throughout the cell cycle, the extent of its association is regulated in a cell cycle-dependent manner. The level of centrosome-associated SZY-20 peaks at prometaphase and metaphase, slowly declines, and reaches a minimal level during interphase.
