I would like to run the following sequence through D-I-TASSER. Unfortunately the length is 1083. Is there a way around the 750 limit in the text paste box? I tried uploading the sequence as a .fasta file from my computer with no luck, I was told the text paste box was empty.

Any help is greatly appreciated. Thank you.

Dear user,

Due to the resource limitation, we limited the sequence to 750AA current.

Please find our pre-build model by D-I-TASSER for your target protein. https://zhanggroup.org/HPmod/data/Q9ULD8/result.zip.

for your case, I think the C-terminal may not be that confident, you can put the C-terminal sequence (cut from the whole sequence) to the D-I-TASSER server and select the AF2 distance and IMG option, to see if the C-terminal can be improved.
