Expression of E(spl)m2-BFM coding region plus 6-10 nucleotides of 5' UTR (to ensure normal translation initiation) is governed by UASt regulatory sequences.
macrochaeta & adult head, with Scer\GAL4sca-537.4
macrochaeta & mesothoracic tergum, with Scer\GAL4sca-537.4
When expression is driven by Scer\GAL4Bx-MS1096 many sensory organ precursors are missing and wing vein L5 is truncated. When expression is driven by Scer\GAL4sca-537.4 several notal bristles and/or head bristles are lost, the dorsocentral bristles being particularly sensitive. Some microchaetae are also lost. Sensory organ precursors fail to be specified.
