8 Expression Patterns

• Primary Identifier: Expr1744
• Remark: Reporter gene fusion type not specified.
• Pattern: F42G10.2 expressed in pharyngeal muscles and several unspecified neurons. The promoter of F42G10.2 was not active in the intestine, anus, or excretory cell. Promoter activity observed throughout the pharynx. GFP observed in the corpus, isthmus and terminal bulb.

• Primary Identifier: Expr1200129
• Pattern: Data from the TransgeneOme project

• Primary Identifier: Expr14340
• Pattern: Labeled EXC-2 is located at the lumen of the excretory canal, in the corpus, posterior bulb, and pharyngeal-intestinal valve of the pharynx, as well as in the uterine seam and intestinal-rectal valve.
• Subcellular Localization: Labeled EXC-2 is located apical to canal cytoplasm, as determined via cross-sectional fluorescence intensity measurements. This result was confirmed by evaluating the subcellular location of EXC-2 relative to a known apical membrane protein, ERM-1 (Gbel et al. 2004). The results demonstrate that EXC-2 and ERM-1 show overlapping expression at the canal apical (luminal) membrane.

• Primary Identifier: Expr15267
• Pattern: IFC-2a/e::YFP is localized in the intestine, the excretory canal, corpus and posterior bulb of the pharynx, pharyngeal-intestinal valve and interfacial uterine cells.

• Primary Identifier: Expr15268
• Pattern: No intestinal expression can be observed for IFC-2a/b/c, which instead presents a very prominent localization in the intestinal-rectal valve. Expression is also observed in the excretory canal, corpus and posterior bulb of the pharynx, pharyngeal-intestinal valve and interfacial uterine cells.

• Primary Identifier: Expr1954
• Remark: Reporter gene fusion type not specified.
• Pattern: Corpus and terminal bulb of pharynx; few head neurons; tail hypodermis; posterior intestine; some vulva, uterine muscles.

• Primary Identifier: Expr1200031
• Pattern: Data from the TransgeneOme project

• Primary Identifier: Expr3025
• Pattern: The iri-1::gfp is expressed in the terminal bulb of the pharynx, amphid socket cells, pharyngeal-intestinal valve, intestine, excretory cell, rectal epithelial cells, and vulva hypodermis. In addition, iri-1::gfp is expressed in the corpus of the pharynx, the pharyngeal neuron I3, the anal sphincter and in the gonad precursor cells Z1 and Z4.
