The Send2 coding sequence carried on an approximately 8 kb genomic fragment is precisely replaced with that of GAL4 resulting in a construct where a 4 kb Send2 upstream sequence regulates expression of a GAL4 driver.
Comment: in secretory cells of mated females only
Send2 reporter drives expression in the spermathecal secretory cells of mated females. It is visible by 3 hours post-mating.
