ftz neural enhancer is fused upstream of a minimal Hsp70 promoter which in turn is fused to an in-frame fusion of Ecol\lacZ-Tag:MT(btau). Btau\MAPT-Ecol\lacZ is composed of a 1.2kb HindIII RsaI Btau\MAPT cDNA, encoding the first 383 amino acids (including sequences necessary for microtubule binding) and Ecol\lacZ fragment starting from codon 5.
Normal neuronal development is not affected with upto 4 copies of P{Cftz/tau-lacZ}. Anterior corner cell behaviour is indistinguishable from wild type and individuals are fully viable.
Carried in plasmid pCftz/tau-lacZ.
