WormMine: ExpressionPattern Expr1133

• Pattern: Expression first appeared in the four descendants of the E cell and later in derivatives of AB.p and C blastomeres. The expression continued in the hypodermis but not gut throughout the remainder of the embryogenesis. In L1, the strongest GFP was signals were observed in the seam cells and the pharyngeal and tail hypodermis. Also noted expression in the excretory duct cell.
• Primary Identifier: Expr1133
• Remark: Reporter gene fusion type not specified. nhr-25::gfp-C causes early embryonic developing arrest, thus none of the embryos showing GFP expression hatched.
• Subcellular Localization: Regardless of NLS, localized to nuclei.
