Description

A EGFP reporter tag is inserted in-frame at the 3' end of the tll open-reading frame, replacing the stop codon and creating a gene encoding a C-terminal protein fusion.

Additional Information
Statement
Reference

GFP-tagged tll protein is detected in type II neuroblasts but not in immature or mature secondary neuroblasts. It is also detected in type I neuroblasts in the brain and in the ventral nerve cord, but at a significantly lower level than in type II neuroblasts

(Rives-Quinto et al., 2020)

tll reporter is most if not all type I neuroblasts in the B1 region of the embryonic brain. The tll reporter is expressed in all three type II neuroblast clusters
