mTOR pathway 2009
The mTOR (mammalian target of rapamycin) is the pathway I'm working on, and I tried to put some of the recent publications in there. If anybody likes to point out a mistake or has any suggestions, please feel free to do so! This isn't supposed to be a good overview that you'd put in a presentation, rather I tried to put together most of the relevant information I could find, most useful for scientists working on this pathway. There are uncertainties and contradictions, so future work has to be done, especialy regarding the mTorc2 (mTOR complex 2) and its upstream regulators and effectors.

This is getting too complicated!
I guess version 2.0 will require 3D glasses... or a Matrix-like brain connection
did I miss something there?
Thanks for the pathway presentation. Indeed, it is handy and have been using it for months that it remains fresh in my memory. Very useful and thanks again for sharing. I like your blog, in general.
I am located in Singapore. In case, if you plan to visit Asia, you are most welcome to the small vibrant country.
I cam across your picture of the mTOR pathway. I would like to use it in a presentation for customers who might be interested in the SIROLIMUS method that Siemens Healthcare Diagnostics has available on their laboratory equipment. The presentation provides a background on Sirolimus, and the pathway is a great depiction of the area that Siro blocks. I don't know for sure how to gain permission to use the picture in my powerpoint. Can you grant me the permission to use the depiction without alteration in my presentation? I will note the link to this article in my presentation.

I would be glad for a copy of the presentation though.
I should put some recent things in there though
