Subject: Re. FlyBase query
Dear Gillian,
The tkv* construct used for the experiments described in our paper (see below)
is indeed downstream of UAS elements. However, the expression of the construct
was not driven by a GAL4 line, but rather by enhancer piracy, and hence the
promoter is unknown. The only information we are in a position to provide is
that the line used is a jump of UAS-tkv* onto the TM3, Sb balancer chromosome.
Please feel free to write to me for further clarifications.
Regards,
Pradeep Das

Dear Pradeep,
thanks for your reply, it was very helpful.
I would just like to confirm whether the UAS-tkv* construct used to make
your tkv* enhancer piracy line is the construct that was described in:
Lecuit et al., 1996, Nature 381(6581): 387--393
I would like to record the details of your tkv* enhancer piracy line as a
personal communication to FlyBase from you. Is that OK ?
Also, do you have a particular designation for the line, as this helps in
naming the construct in FlyBase.

Dear Gillian,
the UAS-tkv* construct described in our paper was made in our lab, so while the
nature of the mutation may be the same as the one in Lecuit et al. (and in
several other papers), the transgenic line itself is unique. The designation we
use for this line is 'SC143' (TM3, Sb, tkv*).
Please cite personal communication from Seo-Hee Cho - he's the student in our
lab that made the lines and characterised them.
Hope that was helpful! Please feel free to email me for further clarifications.
Regards,
Pradeep

Dear Pradeep,
as you made the UAS-tkv* construct in your lab, I will make a new entry in
FlyBase for it.  Is the mutation Q199D, as described in the materials and
methods of your paper for Ubi-tkv ? and is it in the pUAST vector ?
As I've been writing to you, it seems fair if I cite the personal
communication from both Seo-Hee Cho and you, and I'll record that the
construct was made by him in the personal communication, is that OK ?
Sorry to keep e-mailing you, and thanks for being so helpful !

yes to both.
