It all depends on the quartenray structure of the protein. What shape does
the second protein take as opposed to the first one? Also is the second
protein motif exposed? If it is buried within a protein ( in a canyon for
example) then the antibody is not gonna be able to recognize it.
I guess the answer to your question is ' I don't know':) but I think these
points are important to consider.
