Hi Madhurima,
You just found a bug and a badly formatted protein in our
database.
We are currently working on the IntAct web application so we can
sort out this bug and release it with the new version. We should
be able to redeploy a new version by the end of September (worse
case).
The proteins EBI-1058383 and EBI-1058350 are internally created by
our curators because they do not exist in uniprot yet. You cannot
open the molecule view in our IntAct website for the moment but
you can get more information by looking at the interaction result
table and play with the columns that are displayed.
Alternatively, you can download the sequence information of these
proteins in our big FASTA file provided here:
ftp://ftp.ebi.ac.uk/pub/databases/intact/current/various/intact.fasta.
We will work on the issue in the meantime, thanks for reporting
the bug.
Regards,
Marine
