WormMine: ExpressionPattern Expr2026

• Pattern: Expression is seen from 3-fold embryo stage, through all larval stages and through to adulthood. Punctate cytoplasmic and nuclear expression is quite extensive and is seen throughout the worm in bodywall muscle and hypodermis. More specifically the vulC cells of the vulva frequently show strong expression, as do cells of the defecation muscle system.
• Primary Identifier: Expr2026
• Remark: Other strain-- UL952
• Subcellular Localization: Punctate cytoplasmic and nuclear expression is quite extensive and is seen throughout the worm in bodywall muscle and hypodermis.
