WormMine: ExpressionPattern Expr9134

• Pattern: pxn-2 transcriptional GFP reporters containing the 1.8 kb promoter sequence defined by rescue experiments were expressed in the embryonic epidermis. Expression was observed in epidermal precursors beginning in late gastrulation (~200 minutes after the first cleavage), which is ~4 hours before the elongation defects of pxn-2 mutants become apparent at 450 minutes. Ppxn-2-GFP was expressed by most differentiated epidermal cells throughout embryonic, larval and adult development. In adults, Ppxn-2-GFP was expressed in vulval muscles and in a small number of neurons, including PVQ.
