The Nobel Prize in Chemistry for 2004 is shared between three scientists who have made fundamental discoveries concerning how cells regulate the breakdown of intracellular proteins with extreme specificity as to target, time and space. Aaron Ciechanover, Avram Hershko and Irwin Rose together discove ...
a morphogenetic role for the TNF signalling pathway
... One mechanism by which RhoA activity can be regulated is via the RhoGDP dissociation inhibitor (RhoGDI), which can bind to the intracellular domain of p75 (Yamashita and Tohyama, 2003). The binding of RhoGDI to p75 prevents the inhibition of RhoA by RhoGDI, allowing activation of RhoA by an as-yet-u ...
