WormMine: ExpressionPattern Expr15837

• Pattern: PAN-1GFP signal was detected broadly in embryos and early larvae, but decreased substantially in late larvae and adults. Two types of PAN-1GFP subcellular patterns were observed: at the cell membrane and as cytoplasmic puncta. Some prominent PAN-1GFP signal was found in seam cells, a type of epidermal cells that shows stem-cell like division during larval development. These cells were lined up in a single profile at each lateral line and embedded in syncytial epidermis. Between the seam cells and the epidermis, a ring of tight junctions formed on the apical-lateral side of the cells. By colabelling a tight-junction component DLG-1::RFP and PAN-1GFP, we observed that PAN-1 distributed at the lateral basal membrane of seam cells. PAN-1 is also localized on the cell membrane of many ventral cord neurons, including DD neurons at L1 and L2. Therefore, we observed that PAN-1 is localized on the cell membrane.

neuron with cell body associated with the ventral nerve cord.	ventral cord neuron	ventral cord motoneuron	WBbt:0005300
Neuron class of six motoneurons, with cell bodies in the ventral cord, which innervate dorsal muscles. Each cell has a short, posteriorly directed and a longer, anteriorly directed process emanating from its cell body. The anterior process has a branch, which leaves the ventral cord as a commissure and runs round to the dorsal cord.	DD neuron		WBbt:0005270
