Webb18 mars 2013 · These exhibit largely non-redundant functions and are differently expressed, localized, and regulated. The Polo homolog Plk1 is common to all eukaryotes, apart from plants and certain protozoan parasites. Plk4 is also present in most vertebrates and invertebrates and probably arose early on, in a first round of gene duplication.
