The P{PZ} element in P{PZ}grn05930 has been replaced with a P{GAL4} element.
In the ventral nerve cord, grn reporter expression begins at early embryonic stage 12 in a diverse set of interneurons and motorneurons that extend axons along the major axon tracts. With the exception of one doral glial cell, expression is restricted to neurons. Based on overlap with neural markers, expression was identified in the intersegmental nerve motoneurons aCC, RP2 and the U1-5 neurons.
