Genomic fragment containing a C-terminally truncated form of exu (contains only the EXO-like domain). The protein is tagged at the N-terminal end with Venus and Tag:StrepII.
The anterior localization of bcd mRNA is impaired in exu333.T:Zzzz\StrepII,T:Avic\GFP-YFP.Venus/exuVL transheterozygote embryos.
