C-prune is the C-terminal domain of h-prune, overexpressed in breast, colorectal, and gastric cancers, interacting with multiple partners, and representing an ideal target for inhibition of cancer development. Its C-terminal domain results in an intrinsically disordered domain (IDD), and the peculiar properties of gH625 render it an optimal candidate to act as a carrier for this net negatively charged molecule by comparison with the positively charged TAT. A characterization of the recombinant gH625-c-prune fusion protein was conducted by biochemical, cellular biology and confocal microscopy means in comparison with TAT-c-prune. The results showed that the gH625-c-prune exhibited the ability to cross biomembranes, opening a new scenario on the use of gH625 as a novel multifunctional carrier. Keywords: delivery, IDP |
