WormMine: ExpressionPattern Expr1776

• Pattern: A distinct expression pattern in the hypodermal and cuticular regions of all stages was obtained from the Ce-cpl-1 translational fusion construct. Expression of the CPL-1::GFP fusion protein was also observed along the length of the pharyngeal lining in L1-L4 stages, but was restricted to the posterior bulb of the pharynx in adult worms. Furthermore, robust expression was observed in the eggshells surrounding the embryos inside the hermaphrodite and in the regions of the vulva, uterus, and spermatheca. In contrast to the transcriptional reporter construct there was no CPL-1::GFP expression in the gut.
• Primary Identifier: Expr1776
• Remark: No GO_term assigned.
• Subcellular Localization: GFP was detected in the eggshells of laid eggs in different stages of development.

a rigid external coating which is secreted by the hypodermis, seam and some transitional epithelial cells which covers the outer body, the major openings into the body cavity from the exterior, and two large sensory bristles, the male spicules. The cuticle of the spicules, the hook, and of some portions of the spicule channels is especially rigid and is probably sclerotized. Similar sclerotic features are occasionally noted in the ventral surface of the male tail fan.	cuticle	exoskeleton	WBbt:0005755
