WormMine: ExpressionPattern Expr2597

• Pattern: SOP-2::GFP localizes to the cell nuclei of essentially all somatic cells. bxEx99 and bxEx103 arrays produced essentially identical SOP-2::GFP expression patterns.
• Primary Identifier: Expr2597
• Subcellular Localization: SOP-2::GFP localizes to the cell nuclei of essentially all somatic cells and is apparent from the 50-cell stage embryo onward. At first, expression is weak and diffuse within nuclei, but, by the 200-cell stage, it becomes stronger, and distinct nuclear speckles, which is called "SOP-2 bodies," appear. By the comma stage (~400 cells), the nuclei of most somatic cells contain SOP-2 bodies, but their number and size varies among different cell types. Hypodermal and gut nuclei, which undergo endoreduplication, contain large numbers of SOP-2 nuclear bodies (hypodermis, 39.8+/-8.8, n=14; gut, >500, n=2) compared with other cell types (seam cells, 8.8+/-3.7, n=8; neurons, 8.4+/-2.7, n=15). No expression is detected in the nucleolus.
