Contains the jnj coding region plus 409bp of upstream and 154bp of downstream sequence (starting from the 5'UTR and 3'UTR respectively). Six copies of the Tag:HA tag have been inserted at the C-terminal end of the open reading frame.
Expression is observed in all germarial stages in the germline cysts. It is present in oocytes throughout oogenesis and is visible in nurse cells in stages S2-3 and not again until stage S8.
