WormMine: Gene WBGene00000084

• WormBase Gene ID: WBGene00000084
• Gene Name: aex-1
• Sequence Name: D2030.10
• Brief Description: aex-1 encodes a novel, C2 calcium-binding domain protein that is similar to human BAP3 proteins and rat Munc13; in C. elegans, AEX-1 functions in retrograde signaling to regulate presynaptic activity and localization of the synaptic vesicle fusion protein UNC-13; AEX-1 is required for the defecation motor program, specifically the anterior body wall and enteric muscle contractions, and for normal locomotion, male mating, and egg laying; mutation of dgk-1, or a gain-of-function mutation of egl-30, suppresses the aex-1 mutant phenotype; AEX-1 is expressed primarily in the anterior and posterior intestine and in body wall muscle cells; tissue-specific expression in the intestine rescues defecation defects, while expression in body wall muscle cells rescues UNC-13 localization defects; genetic analyses suggest that aex-1 and aex-5, which encodes a prohormone convertase, function in the same pathway to regulate retrograde signaling at neuromuscular junctions.
• Organism: Caenorhabditis elegans
• Automated Description: Involved in several processes, including positive regulation of intestinal lipid absorption; positive regulation of transport; and reproductive behavior. Predicted to be located in exocytic vesicle. Expressed in amphid neurons; body wall musculature; and intestine.

Regulated By Treatment	Description	Algorithm	Primary Identifier
	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
	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
	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.

	Genes that were upregulated in lin-15B(n744).	For each gene in each microarray hybridization experiment, the ratio of RNA levels from the two samples was transformed into a log2 value and the mean log2 ratio was calculated.

All genes with a false discovery rate of <= 5% (q <= 0.05) (Storey and Tibshirani, 2003) and a mean fold-change ratio of >= 1.5 were selected for further analysis.

• Primary Identifier: Expr2009246
• 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: Expr1805
• Pattern: AX4: Although pAX4 contained the full-length aex-1 genomic sequence and was capable of rescuing all aex-1 phenotypes, the fluorescence of this fusion protein was extremely weak. pAX3: Expression of this fusion protein was observed in intestine, some amphid neurons, and body-wall muscles. Anterior and posterior, but not central, intestinal cells had detectable GFP fluorescence. Four neurons in the amphid had observable GFP fluorescence; this was observed only at a late adult stage when using pAX3 but not when using pAX4. The exact identities of these neurons are uncertain, but based on their positions, they do not appear to be the GABAergic AVL and DVB neurons required for the defecation behavior.
