WormMine: ExpressionPattern Expr13896

• Pattern: Examination of the GFP-tagged strain (referred to as F49E8.2:GFP) revealed nuclear expression restricted to the P lineage in embryos beginning in the P4 primordial germ cell. In larval stages, F49E8.2:GFP is present in all germ cells. In adults, F49E8.2:GFP localizes to the nuclei of germ cells in the mitotic zone through entry into meiosis. Strikingly, F49E8.2:GFP expression abruptly disappears in the late pachytene region, and is absent from developing oocytes. OEF-1 expression is detected in the proximal germ cells of L4 animals undergoing spermatogenesis, but not in the proximal germ cells of adult hermaphrodites undergoing oogenesis.
