WormMine: Gene WBGene00001165

• WormBase Gene ID: WBGene00001165
• Gene Name: efn-4
• Sequence Name: F56A11.3
• Brief Description: efn-4 encodes a divergent member of the ephrin family of ligands; efn-4 is required for neuroblast migrations during closure of the ventral gastrulation cleft and subsequent epidermal morphogenesis, possibly functioning independently of EFN-1, EFN-2, EFN-3, and the VAB-1 receptor during morphogenesis; EFN-4 can interact weakly with VAB-1 in vitro; EFN-4 is expressed in neural and epidermal precursors at the 100-cell stage, in head neurons, pharyngeal cells, lateral and tail neurons, and in the ectoderm during epidermal enclosure.
• Organism: Caenorhabditis elegans
• Automated Description: Predicted to enable ephrin receptor binding activity. Involved in several processes, including embryonic morphogenesis; nematode male tail tip morphogenesis; and regulation of axon guidance. Located in axon and neuronal cell body. Expressed in several structures, including CAN; epithelial cell; ganglia; intestinal cell; and somatic nervous system. Human ortholog(s) of this gene implicated in craniofrontonasal syndrome; dysostosis; and stomach cancer. Is an ortholog of human EFNB1 (ephrin B1).

	Strictly embryonic class (SE): genes that are the subset of embryonic genes that are not also classified as maternal.	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_SE

11 Expression Patterns

• Primary Identifier: Expr1030742
• Pattern: Tiling arrays expression graphs

• Primary Identifier: Expr12914
• Pattern: EFN-4-GFP is detectable in intestinal cells prior to int5 intercalation. EFN-4-GFP is not detectable in intestinal cells at later stages, but is abundant in a subset of pharyngeal and valve cells anterior to the intestine. As expected for a secreted protein, EFN- 4-GFP accumulates at high levels in all visible extracellular spaces within the embryo.

• Primary Identifier: Expr12755
• Pattern: EFN-4::GFP is expressed in the nervous system and can be detected in head neurons, the nerve ring and the ventral nerve cord, seam cells, lateral neurons, including the CAN neuron, vulval cells, and tail neurons.

• Primary Identifier: Expr2300
• Pattern: Indistinguishable expression patterns were observed using both methods. EFN-4 was first detected at about the 100-cell stage in a large number of ventral surface cells, identified as neural or epidermal precursors. During and after enclosure of the epidermis, EFN-4 was expressed in many neurons and not in epidermal cells. In later embryos, larvae and adults, EFN-4-GFP was expressed in several head neurons, pharyngeal cells and a small number of lateral and tail neurons, within which EFN-4 was localized throughout the neuronal cell body and in axonal processes.
• Subcellular Localization: EFN-4 was localized throughout the neuronal cell body and in axonal processes.

• Primary Identifier: Expr2011193
• 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).

• Pattern: Time-lapse fluorescence microscopy was performed, including DIC for morphology. Gene expression patterns were summarized in 4 manners: Average over time, Average over time and at different positions along the anterior-posterior (AP) axis, a voxelized representation over time, and on individual cells overlaid from a reference coordinate dataset (https://doi.org/10.1016/j.ydbio.2009.06.014). The analysis was done with a pipeline based on the multi-purpose image analysis software Endrov (https://doi.org/10.1038/nmeth.2478), which further is needed to browse the raw recording data. Thumbnail movies were also generated, using maximum Z projection for the 3D fluorescence channel. Raw recordings available in the Endrov OST-file format are available at https://www.ebi.ac.uk/biostudies/studies/S-BIAD191?query=S-BIAD191

• Primary Identifier: Expr2930
• Remark: Lineage expression: Rn descandents.
• Pattern: Among epidermal cells in the tail, efn-4::gfp was expressed in Rn.a descendants but not in other tail epidermal cells. Expression was first detected in Rn.aa and Rn.ap cells, and expression increased in strength in their descendants. Expression levels among descendants of the same Rn.a cell were similar. Expression was strongest and most frequent in descendants of R2.a and R6.a, intermediate in strength and frequency in R4.a, R5.a, and R7.a, and absent from R1.a and R3.a; expression was not scored in R8.a and R9.a descendants because it was weak and highly variable between individuals.
