WormMine: Gene WBGene00000406

• WormBase Gene ID: WBGene00000406
• Gene Name: cdk-4
• Sequence Name: F18H3.5
• Brief Description: cdk-4 encodes two isoforms of a cyclin-dependent serine/threonine protein kinase orthologous to human CDK4 and CDK6 (OMIM:123829 and OMIM:603368, mutated in cutanous malignant melanoma) which complex with D-type cyclins to regulate progression through the G1 phase of the cell cycle; CDK-4 activity is essential for G1 progression in postembryonic blast cells and as a result, cdk-4 mutant animals generally arrest during larval stages; the lethality generated by cdk mutations, also seen in animals doubly mutant for cdk-4 and cyd-1, a C. elegans D-type cyclin, can be suppressed by mutations in lin-35/Rb suggesting that, as in other organisms, LIN-35/Rb may be a major target of CDK-4/CYD-1 kinase activity; CDK-4 expression is first detected in neuronal and hypodermal lineages during mid-to-late embryogenesis, with postembryonic expression detected in hypodermal seam cells, cells of the P lineage which will give rise to ventral cord neurons, and cells of the somatic gonad, the vulva, and the intestine.
• Organism: Caenorhabditis elegans
• Automated Description: Enables protein serine/threonine kinase activity. Involved in several processes, including G1/S transition of mitotic cell cycle; developmental process involved in reproduction; and positive regulation of cell cycle process. Part of cyclin D1-CDK4 complex. Expressed in gonad; intestine; neurons; and vulva. Used to study cancer. Human ortholog(s) of this gene implicated in several diseases, including carcinoma (multiple); central nervous system cancer (multiple); and urinary system cancer (multiple). Is an ortholog of human CDK4 (cyclin dependent kinase 4) and CDK6 (cyclin dependent kinase 6).

	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.

6 Expression Patterns

• Primary Identifier: Expr2009811
• 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).

• Primary Identifier: Expr1030223
• Pattern: Tiling arrays expression graphs

• Primary Identifier: Expr1156
• Remark: mid-embryogenesis (author) = elongating embryo (wjc)
• Pattern: Initially expressed during mid-embryogenesis, primarily in postproliferative hypodermal cells and neurons in the head, ventral cord and tail. This expression fades during morphogenesis so that when the larvae hatch expression is seen primarily in lateral hypodermal cells known as seam cells. Common sites of expression included the P cells and their descendents, lateral seam cells, and somatic gonad and vulva. Expression in the P lineage, whose descendents give rise to numerous ventral cord neurons, often disappeared once proliferation of the lineage was complete whereas expression in the seam cells and somatic gonad often persisted. cdk-4::GFP was biased towards the uterine cells with minor spemathecal cell expression. The cdk-4::GFP reporter gene was also expressed at high levels throughout the intestine.
