Well obviously you would need information regarding what part of the first
protein the Ab "maps" to, as well as 3D structure (since odds are it will
be a conformational rather than linear epitope), and then *maybe* you can
decide...based on structure of the second protein and whether or not the
epitope region is among the 50% conserved...the same Ab will bind.

Short response: you'll have to try and see. It is impossible to answer
your question based solely upon the information provided.
