WormMine: ExpressionPattern Expr13002

• Pattern: 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.
• Primary Identifier: Expr13002

Definition	Name	Synonym	Primary Identifier
Four processes (canals) of the excretory canal cell each contain a central collecting lumen which feeds to a central lumenal canal in the cell body; the central canal forms a specialized membrane to release fluids into the excretory duct. These five canals form a continuous H-shaped channel which extends almost the full length of the body, generally in contact with the lateral hypodermis and the pseudocoelom.	excretory canal	canal	WBbt:0005775
