WormMine: Gene WBGene00014153

• WormBase Gene ID: WBGene00014153
• Gene Name: vab-23
• Sequence Name: ZK930.3
• Brief Description: vab-23 encodes a novel 253 amino acid coiled-coil containing a C-terminal C4H2 zinc finger domain; VAB-23 is a conserved protein and has a strong homology to human hepatocellular carcinoma antigen (HCA127) (OMIM: 610334); vab-23 is required in ventral neuroblasts for ventral closure and elongation of the embryo, specifically to regulate proper cell contacts between contralateral pairs of ventral epidermal cells; vab-23 is also required for vulval cell morphogenesis; in regulating vulval development, vab-23 acts downstream of the EGFR/RAS/MAPK pathway and the CEH-20 and LIN-39 transcription factors, the latter of which binds vab-23 regulatory sequence; VAB-23, in turn, regulates the expression of the SMP-1 semaphorin, the EFF-1 fusogen, the EGL-26 acyltransferase, and LIN-3/EGF in vulval cells, binding SMP-1 and EGL-26 regulatory sequence in vivo; the highly conserved C-terminal zinc finger domain of VAB-23 is necessary for VAB-23 function; VAB-23::GFP is expressed in the nuclei at the onset of epidermal morphogenesis, predominantly on the ventral posterior of the embryo, ventral neuroblasts, and two posterior ventral epidermal cells; within nuclei, VAB-23::GFP appears to localize to nuclear speckles that correspond to regions of lower DNA content.
• Organism: Caenorhabditis elegans
• Automated Description: Involved in several processes, including embryonic body morphogenesis; epidermis morphogenesis; and vulval development. Located in nuclear speck. Expressed in several structures, including hermaphrodite somatic gonadal cell; ventral uterine precursor; vulval cell; vulval muscle; and vulval precursor cell. Human ortholog(s) of this gene implicated in Miles-Carpenter syndrome. Is an ortholog of human ZC4H2 (zinc finger C4H2-type containing).

	Genes with expression level regulated by genotype (N2 vs CB4856) and age at L3 larva and Late reproduction stage (96 hours at 24 centigrade).	For model 2, authors used 100 permutations to estimate the FDR threshold. Per permutation, genotypes and ages were independently randomly distributed, keeping the among-gene structure intact. Then for each spot (23,232) on the array, model 2 was tested. The obtained P-values were used to estimate a threshold for each of the explanatory factors. Authors also used a genome-wide threshold of -log10 P-value = 2, which resembles an FDR of 0.072 and 0.060 for marker and the interaction age-marker for the developing worms and FDR of 0.050 and 0.065 for marker and age-marker for the aging worms. For the physiological age effect, authors used a log10 P-value = 8 in developing worms (0.012 FDR) and -log10 P-value = 6 (0.032 FDR).	WBPaper00040858:eQTL_age_regulated_developing

	Expression Pattern Group C, enriched for genes involved in metabolic processes.	The significance (P 0.0001) of the relative age (time) was used to determine if a gene was differentially expressed between the three age (time) groups. The effect of this factor explaining gene expression differences was used to determine if the expression went up or down during the two age/time periods (t1 - t2 and t2 -t3). Authors used a permutation approach to determine the thresholds for the different mapping strategies. For each of the used models for eQTL mapping, authors used 23,000 permutations. For each permutation, authors randomly picked a spot; each spot could only be picked once. The gene expression and relative lifespan values were than randomly distributed over the RILs (and time points) and used for mapping. In this way, authors obtained a threshold for each of the explaining factors. For the single time points, authors used a FDR of 0.01 to adjust for multiple testing. The genome-wide threshold for this FDR is -log10 P = 3.8 for each of the three time points. For the combined models (t1 to t2 and t2 to t3), authors used a genome-wide threshold of -log10 P = 4, which resembles an FDR of 0.006, 0.001, and 0.006 for marker, age, and the interaction between marker and age, respectively. To determine the threshold for the single gene examples, authors used 1000 permutations as in the genome-wide threshold. The difference is that they use the gene under study in all of the permutations. The P-values for the gene specific thresholds were determined at FDR = 0.05.	WBPaper00036286:Pattern_C
	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.

• Primary Identifier: Expr8814
• Remark: Picture: Fig 7.
• Subcellular Localization: The VAB-23::GFP fusion protein was localized almost exclusively to the cell nuclei. Interestingly, the subnuclear localization of VAB-23::GFP was not uniform but was rather enriched in discrete, rapidly moving punctae, which is characteristic of proteins involved in pre-mRNA processing or mRNA regulation. Co-staining with the DNA-binding dye DAPI indicated that VAB-23::GFP-containing punctae do indeed represent regions of lower DNA content.

• Primary Identifier: Expr2036085
• 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.

• Primary Identifier: Expr9649
• Pattern: VAB-23::GFP was expressed in the AC, the vulval cells, in the ventral and dorsal uterine cells, the seam cells, the vulval muscle cells, a small cluster of unidentified tail cells, and some ventral cord neurons. Vulval expression of VAB-23::GFP was observed predominantly in the 1° lineage beginning at the time of induction and persisting until adulthood. Even thoughVAB-23::GFP was initially expressed at low levels in all VPCs, expression was downregulated in the 2° lineage during induction and persisted at low levels in the tertiary (3°) cells. VAB-23::GFP continued to be strongly expressed in the VulE and VulF cells of L4 larvae during vulval morphogenesis, although relatively weaker expression was also observed in VulC and VulD at this later stage.
