WormMine: Gene WBGene00004217

• WormBase Gene ID: WBGene00004217
• Gene Name: ptr-2
• Sequence Name: C32E8.8
• Brief Description: ptr-2 encodes an ortholog of Drosophila and human PTCHD3, which definesone of seven paralogous families of sterol sensing domain (SSD)proteins; PTR-2 is required for cytokinesis in somatic cells, but not inthe germline (the converse of PTC-1's function); PTR-2 is partiallyrequired for normal molting from L4 to adult stages; PTR-2 is alsorequired for normal male tail development, growth to full size,locomotion, and viability.
• Organism: Caenorhabditis elegans
• Automated Description: Predicted to enable transmembrane transporter activity. Involved in mitotic cytokinesis and molting cycle. Acts upstream of or within nematode male tail mating organ morphogenesis. Predicted to be located in cytoplasmic vesicle membrane and plasma membrane. Human ortholog(s) of this gene implicated in autistic disorder. Is an ortholog of human PTCHD1 (patched domain containing 1) and PTCHD4 (patched domain containing 4).

	Maternal class (M): genes that are called present in at least one of the three PC6 replicates.	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_M

	Genes that showed oscillating mRNA expression level throughout the 16 hour time courses from L3 larva to young adult.	The following three lines of R code were used to perform the classification: increasing <-2*amplitude-PC1 < -1.7; oscillating <-!increasing & (amplitude > 0.55); flat <-!increasing & !oscillating; Note that the amplitude of a sinusoidal wave corresponds to only half the fold change between trough and peak.	WBPaper00044736:oscillating_dev_expression
	Genes that showed expression levels higher than the corresponding reference sample (embryonic 0hr 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.
