Restrict a view to the C-terminus of a protein

[Bothe, Gerald W]

Hi

in the mutation view, e.g.

https://www.cbioportal.org/results/mutations?case_set_id=all&gene_list=CHEK2%3AMUT&...

the whole gene is shown. This gene has 543 AA, therefore I don't see much detail, many mutations cover each other. How can I restrict the view to just the C-terminus of the protein, e.g. AA 500 - 543?

Thanks

Gerald
