WormMine: Gene WBGene00004750

• WormBase Gene ID: WBGene00004750
• Gene Name: sea-1
• Sequence Name: F19B10.9
• Brief Description: sea-1 encodes a T-box transcription factor; during development, sea-1 functions, zygotically and in a dose-dependent manner, as an autosomal element of the X:A (X chromosome:autosome) ratio that determines C. elegans sex; in opposition to the X signal elements, SEA-1 positively regulates transcription of xol-1, the master sex-determination switch gene that is essential for male development and for setting the proper activity level of the dosage compensation complex; consistent with its role as a regulator of sex determination, SEA-1 is expressed in nuclei of early embryos from approximately the 20- to 100-cell stage of embryogenesis.
• Organism: Caenorhabditis elegans
• Automated Description: Enables RNA polymerase II transcription regulatory region sequence-specific DNA binding activity. Involved in dosage compensation by hypoactivation of X chromosome; positive regulation of transcription by RNA polymerase II; and sex determination. Located in nucleus. Expressed in several structures, including coelomocyte; head muscle; intestine; neurons; and ventral nerve cord. Human ortholog(s) of this gene implicated in Abruzzo-Erickson syndrome; X-linked cleft palate with or without ankyloglossia; and bone disease (multiple). Is an ortholog of several human genes including TBX15 (T-box transcription factor 15); TBX4 (T-box transcription factor 4); and TBX6 (T-box transcription factor 6).

	Genes with expression altered >= 3-fold in dpy-10(e128) mutants.	Data across the wild type series was analyzed using the Significance analysis of Microarrays (SAM) algorithm (to calculate the False Discovery Rate (FDR)).	WBPaper00035873:dpy-10_regulated
	Transcripts of coding genes that showed significantly decreased expression in muscle.	DESeq2 (version 1.24.0). Transcripts with a false-discovery rate adjusted p-value less than 0.05 were considered significantly differentially expressed.	WBPaper00062325:muscle_depleted_coding-RNA

	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

	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

10 Expression Patterns

• Primary Identifier: Expr4413
• Pattern: In wild type animals, detectable expression of sea-1 was limited to the bend and proximal region of the gonad

• Primary Identifier: Expr7511
• Remark: Clone: pUL#JS4G5
• Pattern: Expression was seen from early/mid-embryo stage to late embryo in many cells of the embryo. Hatched nematodes showed expression of GFP in nerves of the head and tail and more faintly in the ventral nerve cord. Some expression was seen in the head muscle and in coelomocytes, with faint and intermittent GFP expression also seen in the intestine.

• Primary Identifier: Expr1200017
• Pattern: Data from the TransgeneOme project

• Primary Identifier: Expr10434
• Pattern: Inferred Expression. EPIC dataset. http://epic.gs.washington.edu/ Large-scale cellular resolution compendium of gene expression dynamics throughout development. This reporter was inferred to be expressing in this cell or one of its embryonic progenitor cells as described below. To generate a compact description of which cells express a particular reporter irrespective of time, the authors defined a metric "peak expression" for each of the 671 terminal ("leaf") cells born during embryogenesis. For each of these cells, the peak expression is the maximal reporter intensity observed in that cell or any of its ancestors; this has the effect of transposing earlier expression forward in time to the terminal set of cells. This metric allows straightforward comparisons of genes' cellular and lineal expression overlap, even when the expression occurs with different timing and despite differences in the precise time point that curation ended in different movies, at the cost of ignoring the temporal dynamics of expression, a topic that requires separate treatment. For simplicity, the authors use the term "expressing cells" to mean the number of leaf cells (of 671) with peak expression greater than background (2000 intensity units) and at least 10% of the maximum expression in that embryo. Quantitative expression data for all cells are located here: ftp://caltech.wormbase.org/pub/wormbase/datasets-published/murray2012/

• Primary Identifier: Expr2015703
• 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.

• Primary Identifier: Expr3766
• Remark: Antibodies raised to an N-terminal peptide of SEA-1 recognized a 43 kDa band in Western blots of wild-type embryonic extract, in agreement with the predicted size of SEA-1. This band is more abundant in extract made from embryos carrying the chromosomally integrated yIs61[sea-1(+)] array, which has multiple copies of sea-1(+), and is missing from sea-1(y356) mutant embryonic extract, confirming the specificity of the antibody, the overexpression of SEA-1 from the yIs61[sea-1(+)] array, and the loss of SEA-1 in the mutant. Consistent with the Western blot, SEA-1 accumulates to higher levels in overexpressing yIs61[sea-1(+)] embryos and is absent from sea-1(y356) mutant embryos
• Subcellular Localization: SEA-1 accumulates in nuclei of young embryos, as indicated by immunofluorescence experiments with anti-SEA-1 antibodies.
