The shortest path from the surface to the nucleus: RBP-J kappa/Su(H) transcription factor.

Communication between cell surface receptors and nuclear transcription factors is of primary importance to multicellular organisms. Since there are numerous molecules involved in this process, their mutual interaction forms complex networks of informational regulation, which is still under extensive investigation. The RBP-J kappa transcription factor interacts directly with the Notch receptor involved in cell lineage commitment, implicating the presence of a uniquely simple communication strategy between the surface receptor and the nucleus.
