A truncated form of arm is expressed under the control of its own promoter. A stop codon has been introduced in the coding sequence after amino acid 757 truncating the protein in the middle of the C-terminal region. arm 3' trailer sequences are also present.
Dominant suppressor of the wghs.2sev rough eye phenotype. Shows a strong genetic interaction with panER1, resulting in adult phenotypes characteristic of reduced wg activity.
Analysed by SDS-PAGE to study protein phosphorylation and stability.
Isolated during a screen for dominant suppressors of the rough eye phenotype caused by wghs.2sev expression during eye development.
