WormMine: ExpressionPattern Expr519

• Pattern: Body wall muscle at embryo. Presumptive GLRDL, GLRDR, GLRL, GLRR, GLRVL, GLRVR, coelomocytes, and anal muscles show expression in addition to body muscle cells at L1, L2, L3 L4 and adult. Distal tip cells of developing gonad in L2, L3, and L4. Spermathecal cells and distal ends of gonad show expression at L4 and adult. Vulval and uterine muscles in adult.
• Primary Identifier: Expr519
• Remark: Essentially same pattern as seen for emb-9 (see Expression Pattern 518). Reporter construct derived from clone that rescues let-2. Transgenic Marker: rol-6(su1006). A transcriptional lacZ fusion construct with more 5' upstream sequences showed little activity.

an accordion-like tube that contains sperm and is the site of oocyte fertilization.	spermatheca		WBbt:0005319
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.	body wall musculature	body muscle	WBbt:0005813
muscle associated with hermaphrodite vulva.	vulval muscle		WBbt:0005821
A free-floating spherical cell lying in the pseudocoelomic cavity of larvae and adult C. elegans which can endocytose many compounds, possibly for immune surveillance. There are six coelomocytes in adult hermaphrodites, and they display prominent cytoplasmic inclusions and vacuoles.	coelomocyte		WBbt:0005751
