WormMine: Gene WBGene00006757

• WormBase Gene ID: WBGene00006757
• Gene Name: unc-18
• Sequence Name: F27D9.1
• Brief Description: unc-18 encodes the C. elegans ortholog of Saccharomyces cervisiae SEC1 and mammalian Munc18 proteins; UNC-18 function as a chaperone for UNC-64/syntaxin, ensuring its anterograde transport from the endoplasmic reticulum to the plasma membrane; UNC-18 also enables the docking of vesicles to synaptic regions before vesicle priming and fusion, and promotes synaptic vesicle exocytosis; UNC-18 may also inhibit excessive exocytosis; UNC-18 is expressed in ventral cord motor neurons.
• Organism: Caenorhabditis elegans
• Automated Description: Enables syntaxin binding activity. Involved in chemical synaptic transmission and positive regulation of neurotransmitter secretion. Located in axon. Expressed in intestine; nervous system; and uv1. Used to study alcohol use disorder and developmental and epileptic encephalopathy. Human ortholog(s) of this gene implicated in West syndrome; developmental and epileptic encephalopathy 4; and familial hemophagocytic lymphohistiocytosis 5. Is an ortholog of human STXBP1 (syntaxin binding protein 1).

	Transcripts that showed significantly increased expression in L1 neural cells comparing to in adult neural cells.	DESeq2 (v1.18.1) fold change > 2, P-adj<0.05, using BenjaminiHochberg correction.	WBPaper00060811:L1_vs_adult_upregulated_neural
	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
	Genes significantly enriched (> 2x, FDR < 5%) in a particular cell-type versus a reference sample of all cells at the same stage.	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.

10 Expression Patterns

• Primary Identifier: Expr2035989
• 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: Expr8270
• Remark: Picture: Figure 4, Figure 5.
• Pattern: In transgenic animals, this reporter (unc-18::YFP) recapitulated the previously observed expression in the hermaphrodite (see Expr1518). In the male, unc-18::YFP showed the same expression in the ventral cord and head neurons, but also had strong expression in the gonad. The expression was strongest in the 'valve region', a non-neuronal tissue that lies at the junction of the seminal vesicle and the vas deferens. Expression was also present in most, if not all neurons in the male tail.
