WormMine: ExpressionPattern Expr268

• Pattern: A long transcript mec-9lacZ fusion (TU#165) was expressed only in the 6 touch cells and occasionally in the PVD cells. A fusion specific to the short transcript (TU#160) was expressed in about 25 cells in the head and 50 cells in the ventral cord. Replacing lacZ with the gfp coding region, which permitted visualization of cell processes (in fusion TU#163), showed that the expressing cells were neurons. An integrated line (uIs10) with a mec-9lacZ fusion (TU#171) designed to be expressed in both transcripts was expressed in both sets of cells.
• Primary Identifier: Expr268
• Remark: Data modified according to Shawn Lockery's expression pattern curations. Reporter gene fusion type not specified.
• Reporter Gene: [mec-9::lacZ] or [mec-9::gfp] . Multiple lacZ or gfp fusion constructs.
