3'-untranslated conservation common or not?

[John Watson]

As I understand it:

UTR's between species homologs often show conservation.  UTR's of subtypes (of
a given receptor, kinase, whatever) within a single species do not. This lack
of conservation allows for EST clustering based on 3' UTR sequence.
