WormMine: ExpressionPattern Expr1964

• Pattern: Expressed in most somatic cells in embryos abd young larvae; however, the GFP reporter construct did not express in a subset of embryonic cells that give rise to the central part of the worm. Later during larval development, expression was consistently detected in cells of the head, the hypodermis, and the tail. Because the expression of transgenes is silenced in the germline, mep-1::gfp was not observed in the germline.
• Primary Identifier: Expr1964
• Subcellular Localization: In all cases, MEP-1::GFP was nuclear.
