WormMine: Gene WBGene00020652

• WormBase Gene ID: WBGene00020652
• Gene Name: egg-4
• Sequence Name: T21E3.1
• Brief Description: egg-4 encodes a pseudotyrosine phosphatase; egg-4, along with egg-5 which also encodes a pseudotyrosine phosphatase, are required for the egg-to-oocyte transition and embryonic development; EGG-4 and EGG-5 function to negatively regulate the activity of the MBK-2 DYRK family kinase by sequestering MBK-2 at the oocyte cortex and, in the case of EGG-4, by inhibiting its enzymatic activity; EGG-4 physically interacts with MBK-2 and in in vitro assays, appears to function as a mixed-type inhibitor of MBK-2 kinase activity; EGG-4 localizes to the oocyte cortex and nuclei.
• Organism: Caenorhabditis elegans
• Automated Description: Enables protein kinase binding activity and protein kinase inhibitor activity. Involved in cortical actin cytoskeleton organization; female gamete generation; and positive regulation of protein localization to cell cortex. Located in cell cortex and nucleus. Expressed in germ line and oocyte. Human ortholog(s) of this gene implicated in gastric adenocarcinoma. Is an ortholog of human PTPRG (protein tyrosine phosphatase receptor type G) and PTPRZ1 (protein tyrosine phosphatase receptor type Z1).

	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

7 Expression Patterns

• Primary Identifier: Expr8937
• Remark: Picture: Fig 2.
• Subcellular Localization: Associated with the cortex of developing oocytes and newly fertilized embryos. In oocytes and newly fertilized embryos, GFP:EGG-4 colocalize with mCherry:EGG-3. In dissected gonads, all antibodies labeled the cortex of developing oocytes in a pattern that was identical to the GFP fusions.

• Primary Identifier: Expr8837
• Remark: Picture: Figure 4B, 4C, Figure S6
• Subcellular Localization: EGG-4/5 localize to the cortex of oocytes. In addition, EGG-4/5 were also detected in oocyte nuclei. The cortical and nuclear signals were eliminated by RNAi codepletion of EGG-4 and EGG-5, confirming that they correspond to endogenous EGG-4/5. Staining of hermaphrodites homozygous for single deletions in either EGG-4 or EGG-5 gave the same pattern as wild-type, confirming that EGG-4 and EGG-5 are both expressed in oocytes. In zygotes in meiosis II, EGG-4/5 were enriched on subcortical puncta, also positive for EGG-3. EGG-3-positive puncta invade the cytoplasm during meiosis II. EGG-4/5 puncta, in contrast, were prominent only near the cortex and around the sperm pronucleus. No EGG-4/5 were detected above background in 2-cell embryos.

• Primary Identifier: Expr4156
• Remark: Curated by authors based on online in-situ hybridization database (Y. Kohara, personal communication; http://nematode.lab.nig.ac.jp).
• Pattern: Expressed in proximal germline.

• Primary Identifier: Expr2011202
• 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).
