The RMCE cassette of the Mi{MIC}mblMI00139 insertion has been replaced with a Trojan-GAL4 cassette. The insertion is in a coding intron of mbl and is predicted to gene trap the gene. (Note that if this gene has multiple transcripts, only those where the insertion is in a coding intron are predicted to be trapped).
The translational mbl reporter is expressed in third instar larval photoreceptors. In the brain, expression is observed mainly in post-mitotic neurons with some expression in glial cells. It is also detected in muscles. An intersectional strategy was used to label single cells. mbl reporter is observed in L1, L4, R7 and R8 neurons. mbl is expressed in a cell-specific manner that correlates with the expression of Dscam2 exon 10B but not 10A. It is not detected in mushroom body neurons that express Dscam2 exon 10A in adults.
