Hello all,

This past Friday I defended my doctoral thesis, making me the second PhD to be produced thanks to GPUGRID.net. I owe you all a great debt of gratitude for supporting my work. My thesis covered my work on the study of complex binding processes in membrane proteins and disordered peptides. The membrane work was related to the enzyme FAAH and another work we are hoping to publish very soon. The disordered protein work was also a really great surprise for us, and will be continued further. The thesis itself will be published publicly after an embargo period (due to the still-unpublished works it contains). We will post the link as soon as it's available.

I must also announce that I will be leaving GPUGRID and moving on. I haven't accepted a position yet, but it is looking like I will be moving to a university in California in the next few months. It is a great opportunity and I'm very excited about it. I will continue to push forward biology with the methods and applications that I have learned working on here.

Thanks again and onward,
Nate

Hi everyone,

We are very pleased to announce the publication of our latest research article, titled "Kinetic modulation of a disordered protein domain by phosphorylation", which was published yesterday in the journal Nature Communications. You can see the official journal page link here. Since we know most of you don't have access to the fancy formatted version from Nature Publishing Group, we have placed the our less-fancy formatted pre-print version of the article here (first PDF link at the top of the page).

Since I am sure the title and abstract is quite cryptic/confusing to everyone, let me explain what we discovered and why this work was important. The main focus of the paper was a disordered protein domain called KID. Disordered proteins like KID do not have any rigid structures (so no x-ray crystal structures), and are in fact very flexible like polymers. However, despite being flexible they are very important and common in many different aspects of cell biology. They are important in many protein-protein interactions, such as ones that are important in communication inside the cell. They are frequently involved in many diseases like cancer (among many others).

KID is a protein that has been studied for more than 15 years, and a lot was already known about it. Other proteins in the cell chemically modify KID through a process known as phosphorylation, which then causes it to bind to specific proteins. It binds most famously to a protein known as KIX. The behavior of KID in the phosphorylated and normal state has been studied by a technique known as NMR (a cousin of MRI), and the binding of KID to KIX has also been studied this way. However, what we discovered in our study—and not seen by any other method yet—was that when KID is phosphorylated, it undergoes an a slowdown in its motions and forms a temporary, partially folded state. We believe this state is important in the binding process, and modelling and comparison with previous experiments also suggest this. This work is significant because it is the first time anyone has shown that such chemical modifications could change the behavior of a protein in this way, and also that it could have important consequences for the way proteins interact.

If you have questions, please ask away. We will assign badges and update the webpage soon.

There is now plenty of space on the server so no one should be having upload/download problems. Of course, please let us know if any of you still has problems. We still have work to do to ensure this doesn't happen again, but that's for us to worry about.

Hello all.

The NOELIA_SH2eq workunits were all failing, so those have been cancelled.

There some other groups that follow the naming pattern NOELIA_TRPXXX. Those continue to run, because from what I can tell the ones that are being sent out now do not have a problem. The first post in this thread (http://www.gpugrid.net/forum_thread.php?id=3770&nowrap=true#36977) refers to a group that was cancelled, fixed and resent earlier in the week. However, if you continue to have problems with those please let me know here.

Hey guys,

We're looking into it. Unfortunately Noelia is away right now so we may have to cancel them for now. Thanks for catching it and pointing it out.
