ddl-1 expression is found in the pharynx, intestine, body wall muscles, vulva muscles, spermatheca, and several head and tail neurons.

Subcellular Localization
Using a GFP-tagged DDL-1 driven by the endogenous ddl-1 promoter, DDL-1::GFP expression can be found primarily in the cytoplasm of intestinal cells, pharyngeal cells, and a number of neuronal cells in the head and tail.

an accordion-like tube that contains sperm and is the site of oocyte fertilization.
A chain of very large cuboidal cells forming a wide central lumen in which food arrives from the posterior pharynx, is digested, and from which waste products proceed to the rectum. Intestinal rings form in groups of two and four cells surrounding the common lumen; thus the epithelium is only one cell deep at any point, with neighboring cells firmly secured to their neighbors by apical adherens junctions. These cells have very large nuclei and many large vacuoles, yolk granules, and other inclusions; the latter increase in number and electron density as the animal ages.
Longitudinal bands of muscle cells surrounding animal body, with one band running in each quadrant of the body, regulated contraction and relaxation of these muscles cause locomotion.
the feeding organ, a neuro-muscular pump in the head of the animal, used to ingest food, bacteria suspended in liquid, filter them out, grind them up and transport posteriorly into the instestine.
