You can perform such a search in PIR website. Go to
and set the following fields and queries (see snapshot below): UniProtKB
ID/AC "not null" (will retrieve proteins from UniProtKB)
AND Molecular Weight "80<(kD)<=90" AND Organism Name "homo sapiens"
This will retrieve human proteins in UniProtKB that matches the
specified molecular weight range.
You can save the file as table, open it for example as an excel
spreadsheet and sort it as needed.
Hope it works OK.
