Any variation in the cellular or subcellular pattern of expression of a gene product produced by exogenous DNA that has been introduced into the organism compared to its expression in control animals.
Animals exhibit defects in the cell-mediated uptake of external materials via receptor activity. Receptor-mediated endocytosis ensures specificity of transport and generally occurs via clathrin-coated pits and vesicles. In C. elegans, this is often judged by the lack of yolk uptake in oocytes.
