All Janelia lexA stocks (a.k.a. "Rubin lexA" lines) currently available at Bloomington are listed here. These lines express lexA under the control of defined sequence fragments from either flanking non-coding or intronic regions of associated genes.
Data on the expression patterns generated by these lexA lines is available at Janelia's FlyLight site.
Important expression information: The vast majority of the sequence fragments used in these constructs were also used in the GMR_Brain_exp_1 collection of GAL4 driver lines (FBlc0000201, see the Janelia GAL4 collection at the BDSC). It is important to note that most of these lexA constructs are inserted in the attP40 site at 25C7 on 2L, whereas the GAL4 insertions are in attP2 at 68A4 on 3L (this was done in order to avoid possible transvection effects while using both lexA and GAL4). Because genomic position effects differ between these sites, lexA and GAL4 lines carrying the same sequence fragment can have significant differences in their observed expression patterns; generally the lexA patterns are a subset of the GAL4 pattern.
