Expression Pattern :

Pattern  Expression of is first detected in the nucleus of cells as they move inward into the gastrula. As the cells arrange into the endodermal and mesodermal layers, mRNAs are detected within cytoplasm. Expression continues as the intestinal cells and the precursors of the pharynx form a central cylinder with the myoblasts filling in between this cylinder and the outer layer of cells. Strong expression is detected in the myoblasts. The expression in the pharyngeal and the intestinal cells is relatively weak. Primary Identifier  Expr3984
Remark  The expression patterns of lam-1 and lam-2 are identical during embryogenesis. Subcellular Localization  Expressed in nucleus and later in cytoplasm.

Definition Name Synonym Primary Identifier
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. intestine gut WBbt:0005772
