Expression Pattern :

Pattern  The gfp-tagged genomic exc-4 locus, which is capable of rescuing the exc-4 mutant phenotype, shows expression in the excretory system, hypodermis, vulva, pharyngeal muscle, rectal gland, tubular rectal epithelial cells, and tubular neuronal support cells in the head and tail. EXC-4 protein showed highly specific patterns of subcellular localization. Taken together, EXC-4 localizes to very distinct membranes that undergo substantial remodeling (growth and fusion) in order to create diverse, often tubular membrane structures. EXC-4 localizes in amphid sheath cells in the head and epithelial cells in the anus. Primary Identifier  Expr2809
Subcellular Localization  In the excretory system, EXC-4 localizes to the lumenal membrane of the excretory cell, the duct, and the pore cell. Apical lumenal localization is also observed in the tubeforming cells generating the anus. In the lateral seam cells of the hypodermis, EXC-4 localizes directly adjacent to the adherens junction marker AJM-1 to a compact subapical belt of plasma membrane called the apical junction. In phasmid and labial sheath cells, EXC-4 selectively localizes to the extreme tip of the sheath cell membranes, which enwrap the dendritic ending of sensory neurons and fuse with themselves to form an elongated tubular structure exposed to the sensory environment.
