Contains a genomic EcoRI-XhoI E(spl)mγ-HLH fragment extending from -947 to +2078 downstream of the transcribed region. A GFP tag has been inserted into a ClaI site in the E(spl)mγ-HLH open reading frame.
E(spl)mγ-HLHT:AvicGFP drives expression at the medial edge of the neuroepithelium of the developing optic lobe. It co-localises with Patj protein in 2 to 3 cells, the transitioning neuroepitheliuml cells.
