His research interests include determining posttranslational modifications on EBOV glycoproteins and antiviral strategies for severe virus infections.
In certain cases, the controlled variable directly regulates the activities of the stress gene products (usually specific enzymes) in a posttranslational manner, forming a short feedback loop that bypasses the transcriptional control (Figure 2A,D, dashed lines).
Rheb belongs to the Ras family, which encodes a carboxyl-terminal CAAX box, suggesting that the protein undergoes posttranslational farnesylation--the membrane localization of Rheb through farnesylation is important for upstream regulation of mTOR signaling (Basso et al.
They may hide within normal protein bands and remain undetected or, owing to posttranslational modifications, they may be so broad that they can hide in plain sight.
