A 4.5kb genomic fragment located upstream of the 5' end of prc regulates expression of a GAL4 driver.
The marker line is expressed with the same pattern as prc in late embryos and larvae. It is expressed in cardial cells in embryos and in fat body in larvae.
ScerGAL4prc.4.5 drives expression in a subset of zfh1-expressing pericardial cells.
