Expr13002

An extrachromosomal array containing 1.6 kb of the presumptive C46E1.3 promoter linked to gfp is strongly expressed both in the excretory canal cell and in the glial amphid sheath cells. Expression within the canal cell begins soon after the cell is born, and persists throughout the lifetime of the animal. A translational construct expressing C46E1.3 cDNA linked to GFP solely within the canal and head mesodermal cell is strongly expressed within the canal cytoplasm.
