| Pattern | Expression first detected in embryos though to adulthood. In L1, strong staining detected in the pharynx and in 2 laterally located cells (NLS-lacZ staining). The pharyngeal cells are muscle cells which occupy most of the body of the pharynx and the lateral cells were CAN neurons based on the position of the nucleus and axon morphology. Both pharyngeal muscle and CAN neurons express reporter as embryo through to adulthood. Also stained were several cells in the tail region. These include the B and Y cells (forming male spicule) from L1 to adult, the hypodermal blast cells T in the L1 and some of its progeny in later stages. In L1, subset of cells in ventral nerve cord and DA identified as DB neurons (cholinergic motor neurons innervating dorsal body wall muscles) stain. Cells identified by GFP: GFP without NLS revealed expression in distal tip cells (DTC) spermatheca and uterus. It is not clear if GFP is expressed by somatic cells of the gonad or by the germline cells (namely sperm) in the spermatheca. Expression in uterus was seen outside the embryos. It is not clear which cells expressed the reporter in uterus although observation of NLS-lacZ and NLS-GFP indicated that some somatic cells of the gonad expressed CePAKGFP without NLS. There is expression in many hypodermal cells surrounding the embryos during the morphogenetic stage. C-terminus two amino-acids of CePAK replaced with GFP coding sequence and fusion protein was expressed from the CePAK promoter used to analyze intracellular localization (pCPK2.77). CePAK GFP was enriched at cell surface in pharyngeal muscle cells especially condensed at cell boundaries. In CAN neurons CePAK GFP detected in cell bodies and along the axons. CePAK GFP localized to cell bodies and their processes running along the excretory canal on the lateral surface of adults. | ||
