'Kiss of Death' Discoverers Get Nobel Prize

baldinux writes "Science Daily has written an article describing the cellular process of regulated protein degredation, which has landed three people the Nobel Prize in Chemistry. According to the article, this finding could greatly help researchers understand ubiquitin-mediated protein degradation, making it possible to develop drugs to treat cervical cancer, for example."

      Interestingly there are diseases caused by malfunctioning ubiquitin ligase. The mental retardation disorder Angelmans disease is caused by a knockout of the ubiquitin ligase E6-AP on the maternal chromasome. Due to genetic imprinting, the maternal form is only used in the brain, so this is like a brain specific knockout of this ligase.

      It's not known exactly what targets of E6-AP are responsible for the disease, but in a mouse model the protein CaMKII was hyperphosphorylated and deactivated. CaMKII is one of the major proteins in the brain (approx 10% of brain protein by mass), and it is essential for Long Term Potentiation, a major mode of synaptic plasticity. This is exciting because it's the first time that CaMKII and LTP deficiancies have been linked to learning in humans. Protein phosphatase activity was also reduced in these brains, suggesting a phosphatase deactivation as the proximal cause of CaMKII hyperphosphorylation. Elucidating how E6-AP knockout leads to phosphatase dysregulation will be a large part of my thesis research, if I can ever get some phospho-CaMKII antibodies that work...

Degradadtion of macromolecules like proteins (through ubiquitine pathway discovered by the Nobel laureates) or RNAs is, however, primarily a way to control different cellular processes. The cell adjusts to different needs by altering the set of proteins that it contains (called the proteome). If proteins were infinitely stable there would be no way of up- or downregulating their levels - once made they would stay there forever. So proteins (and mRNAs that encode them) have a built-in end-of-life mechanism that, together with varying the synthesis rate, makes regulation possible. There is more to it - protein degradation is also used to remove damaged or incorrectly made proteins. So, to sum it up: protein degradation is essential for both regulation and quality control of cell's proteins. Even though there are no direct practical applications so far, the significance of the discovery is great - we do know that if something goes wrong with the cell's regulatory mechanisms we get cancer, understanding ubiqutination brings us closer to understanding how cancer happens.

    The biggest problem to developing any potential theapies from these groundbreaking discoveries is to figure out how to target particular proteins or classes of proteins. There are numerous E3 ubiquitin ligases in cells that target a varety of proteins for degradation. However, the molecular mechanisms by which this recognition takes place is still rather uncertain. The structure of the molecular interaction must be determined at atomic resolution (A difficult process which commonly uses X-ray crystallography and very, very intensive computing).

    I see two methods which would lead to useful therapies:

    The first is the simplest and will therefore also most likely be the first viable strategy: harnessing natural ubiquitin ligases to target and downregulate harmful proteins. This means that any therapies will be limited to natural ubiquitination processes. Humankind will find ways to make these reactions better, or ways stimulate them in diseased cells.

    The second approach is de novo design. Once the structure of the target is determined, enzymes can be desgined to target it for ubiquitination/degradation. However, this requires an understanding of biochemistry far beyond what currently exists. Not only does the therapeutic enzyme have to recognize the target, but it must also catalyze the ubiquitination reaction. At this time, I do not believe that anyone has designed a functional protein-based enzyme from the ground up. This technique has greater potential, as we could target ANY protein we dislike, but we are not quite able to implement it yet.

      The problem here is that in order to tag and then transport the beta amyloid proteins to the proteosome for degradation, you first need to break up the plaque, where they are otherwise not accessible/transportable. But if you figure out a way to do that the natural degradation of the proteins will likely take place on it's own, assuming it is still functioning.
