engrailed + en-lacZ

Expression: engrailed (en) is expressed in NB 1-2, the median NB, and all row 6 and 7 neuroblasts from the time of their formation through S5. Check out the map for details. At stage 16 en is found in a subset of neurons both in the anterior and posterior compartments (see Cui and Doe, (1992) for the names of neurons).

Phenotype: Unknown

Other remarks: The 4D9 anti-invected antibody can be used to follow en expression. It makes a good landmark for positioning and double-labels.

References: The Flybase reference for en might be useful.
