WormMine: ExpressionPattern Expr1395

• Pattern: Similar expression patterns were obtained using either the BAR-1 antibodies in immunocytochemistry experiments or by direct observation of the functional BAR-1-GFP. BAR-1 is present in P3.p through P8.p in the late L1/early L2 stage and disappears in the mid-L3 stage before the first divisions of P3.p-P8.p. Did not observe BAR-1 in P1.p, P2.p, P9.p, P10.p or P11.p at this time. P6.p occasionally showed higher BAR-1 expression than the other vulval precursor cells, and was often observed to be the last vulval precursor cell to lose BAR-1 staining. In addition to the vulval precursor cells, BAR-1 is expressed in several other postembryonic cells, including the seam cells , cells in the somatic gonad and P12.
• Primary Identifier: Expr1395
• Subcellular Localization: In the vulval precursor cells, BAR-1 is predominantly cytoplasmic, with some protein present in the nucleus and some at cell junctions.
