Dear All

I'm Stefano Berto and I'm working in the Katja Nowick group as a PhD
student. In the signature you can easily find my project.

Nowadays I'm working with Transcription factors and the differences
between humans and closely related species.
Thus I found very useful your accurate annotations.

Unfortunately I detected an error downloading a sequence of ZNF717.

This Zinc Finger can be easily found in catalogue:
http://znf.igb.uiuc.edu/human/action/exploreView?type=locus&id=732

and also in your database, Blatting the sequences and find the locus in
the Chromosome.

The problem that I noticed is the protein sequence of ZNF717.

From
http://znf.igb.uiuc.edu/human/action/exploreView?type=locus&id=732
I checked the domains of the protein (KRAB, fingers etc) finding a correct
annotation of the protein.

But if I download the protein sequence there is an error.
In fact, I tried to detect the Zinc Finger domains in the sequence
download and I found some mistakes about some undetectable domains.

Here I'm explaining the problem:

http://znf.igb.uiuc.edu/human/action/exploreView?type=locus&id=732
Here there are the list of domains.
I took this ZNF domain:
YECNECGKSFHQKANLQKHQGIHTGEKP
This is the 18th ZNF domain but I noticed the error in other motifs.

Now I download the protein sequence from the same catalogue and I tried,
with the alignment tool, to detect the sequence but unfortunately I
couldn't.


Thus I blatted the finger sequence in the UCSC website finding a 100% of
identity with a locus in the Chr 3. It is completely inside the ZNF717.

The ERROR is here. In fact I clicked in the browser and, as you understand
if you are following my steps, the SEQUENCE in the browser is completely
different:
MNVMNVENPFIRRQIFRSIKVFTRGRN

Moreover I double checked with the translation of the chromosome locus and
it will give me the CORRECT zinc finger sequence
(YECNECGKSFHQKANLQKHQGIHTGEKP).

Moreover the Refseq in your database is the same that I had from the
catalogue and it is wrong too.

Thus I guess there is a mismatch between the database and the reference
sequence that you can download.
I got in one hand one plausible result but on the other hand a wrong
reference sequence.

Could you check the error?

I hope you can understand the explanation.
I did my best.
By the way, if you need more information, don't hesitate to contact me.

Looking forward to hear from you soon
Best Regards
Stefano
