WormMine: ExpressionPattern Expr1865

• Pattern: FEH-1 antibodies in whole-mount immunofluorescence analysis showed a largely prominent localisation of the protein in the pharynx at all stages of development, from three-fold stage embryos to adults. Barely detectable staining could be observed also in some neurons in the nerve ring and in the nerve chord and in the tail. In the pharynx the fluorescent signals start from the most terminal end of the organ and extend posteriorly to the second pharyngeal bulb and the attachment to the intestine.
• Primary Identifier: Expr1865
• Subcellular Localization: Part of the protein appears to uniformly fill the cytoplasm of the expressing cells but an important fraction appears to associate with some sub-cellular compartment/structure in the shape of filaments that form, at the level of the second bulb, a characteristic basket-like structure.

	The C. elegans life stage spanning 620-800min(hatch) after first cleavage at 20 Centigrade. Cell number remains at ~560 cells, with some new cells generated and some cells go through programmed cell death. A stage after elongation is over. The last stage of embryogenesis. Also called pre-hatched embryo, late embryo or morphogenetic embryo.		fully-elongated embryo Ce	WBls:0000021
	The C. elegans life stage spanning 520-620min after first cleavage at 20 Centigrade. Cell number remains at ~560 cells, with some new cells generated and some cells go through programmed cell death. The shape of embryo is elongated and tripple fold. A stage between 2-fold embryo and fully-elongated embryo. Also called pretzel embryo or pretzel stage.		3-fold embryo Ce	WBls:0000020
