WormMine: Gene WBGene00013355

• WormBase Gene ID: WBGene00013355
• Gene Name: gck-3
• Sequence Name: Y59A8B.23
• Brief Description: gck-3 encodes a STE20-related kinase, required for normal excretory canal tubules, that is regulated by WNK-1 and in turn inhibits CLH-3; GCK-3 is expressed in oocytes and the excretory cell; GCK-3 binds the C-terminus of CLH-3B in both two-hybrid and GST affinity assays; GCK-3 inhibits a fast gating process in CLH-3B by phosphorylating it, both reducing the magnitude of CLH-3B's responses to hyperpolarization and slowing them; gck-3(tm1296) mutants are sterile, perhaps because they lose sperm from their spermathecae; gck-3(tm1296) mutants also have defective excretory canal tubules; both the fertility and the excretory canal phenotypes of gck-3(tm1296) are partially suppressible by the null clh-3(ok763) allele; a wnk-1 phenotype similar to gck-3(tm1296)'s is suppressible by constitutively activated GCK-3; and gck-3(RNAi) constitutively activates CLH-3B in immature oocytes; GCK-3 is phosphorylated by WNK-1 in vitro, and gck-3 mutants phenotypically resemble wnk-1.
• Organism: Caenorhabditis elegans
• Automated Description: Enables protein kinase binding activity and protein serine/threonine kinase activity. Involved in epithelial tube morphogenesis; hyperosmotic response; and multicellular organismal-level water homeostasis. Acts upstream of with a positive effect on positive regulation of gene expression. Located in cytoplasm. Expressed in body wall musculature; excretory system; hypodermis; oocyte; and spermatheca. Is an ortholog of human OXSR1 (oxidative stress responsive kinase 1) and STK39 (serine/threonine kinase 39).

	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

	Genes that showed expression levels higher than the corresponding reference sample (L3/L4 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.
