WormMine: Gene WBGene00000812

• WormBase Gene ID: WBGene00000812
• Gene Name: csk-1
• Sequence Name: Y48G1C.2
• Brief Description: csk-1 encodes an ortholog of C-terminal Src kinase (Csk) that probablyinhibits SRC-like tyrosine kinases in pharyngeal muscle cells; theC-terminal tyrosines of the SRC-like kinases SRC-2/KIN-22 and SRC-1 areevolutionarily conserved, and phosphorylated by CSK-1, which inhibitsSRC-2/KIN-22 and SRC-1 in vivo; csk-1 is co-expressed with src-2/kin-22 and src-1 inpharyngeal procorpus and metacorpus; csk-1(RNAi) animals are grosslynormal, but overexpression of csk-1 induces an abnormal pharyngealphenotype.
• Organism: Caenorhabditis elegans
• Automated Description: Enables protein tyrosine kinase activity. Involved in several processes, including feeding behavior; muscle cell development; and nematode larval development. Located in cell-cell junction and plasma membrane. Expressed in several structures, including anus; head neurons; hermaphrodite somatic gonadal cell; pharyngeal muscle cell; and vulval cell. Human ortholog(s) of this gene implicated in hepatocellular carcinoma. Is an ortholog of human CSK (C-terminal Src kinase).

	Transcripts expressed in neuronal cells, by analyzingfluorescence-activated cell sorted (FACS) neurons.	DESeq. False discovry rate (FDR) < 0.1.	WBPaper00048988:neuron_expressed
adult vs dauer larva	Transcripts that showed differential expression in adult vs dauer lava in N2 animals at 20C.	N.A.	WBPaper00050488:adult_vs_dauer_regulated_N2_20C
	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.

7 Expression Patterns

• Primary Identifier: Expr1030503
• Pattern: Tiling arrays expression graphs

• Primary Identifier: Expr2312
• Remark: Reporter gene fusion type not specified.
• Pattern: Signals were detected in some neurons (ASE, ADF, AVA, AUA, RMDV and BAG) in the head region, the anchor cell, the vulva, the cells around the anus, the body wall muscle, pharyngeal muscles in procorpus and metacorpus and distal tip cells of gonad.

• Primary Identifier: Expr8539
• Remark: Picture: Figure 3.
• Pattern: The expression of GFP-CSK-1 became detectable at around comma stage, when pharynx begins to organize. At the loop stage of embryonic development, GFP-CSK-1 expression was widely detectable in embryos, with high levels of expression observed in the pharynx, especially at cell-cell boundaries. At the L1 larval stage, GFP-CSK-1 expression was highly concentrated in the pharyngeal muscles, although modest expression was detected in body wall muscles, anchor cells and tail region. At adult stages, GFP-CSK-1 was seen in the pharynx, specifically localized along muscle fibers and cell membranes in the procorpus and the terminal bulb.
• Subcellular Localization: Localized on cell-cell boundaries, muscle fibers and cell membranes.

• Primary Identifier: Expr2010549
• 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).
