Protein Degradation by the Ubiquitin-Proteasome Pathway in Normal

Figure 1. The ubiquitin (Ub)-proteasome pathway (UPP) of protein degradation. Ub is conjugated to proteins that are destined for degradation by an ATP-dependent process that involves three enzymes.

Role of arginine-tRNA in protein degradation by the ubiquitin

Degradation of intracellular proteins through the ubiquitin and ATP-dependent proteolysis pathway involves several steps. Initially, ubiquitin is covalently linked to the ... It was shown that a free -NH2 group is one important feature of the protein structure recognized by the ubiquitin ligation system4,5, and that the...

Insulin Resistance Accelerates Muscle Protein Degradation:

Thus, insulin resistance causes muscle wasting by mechanisms that involve suppression of PI3K/Akt signaling leading to activation of caspase-3 and the ubiquitin-proteasome proteolytic pathway causing muscle protein degradation.

Heat Shock Response and Protein Degradation: Regulation of HSF2 by

HSF2 is a labile protein which accumulates during proteasome inhibition. Activation of HSF2 during down-regulation of the ubiquitin-proteasome degradative system suggests that either HSF2 or a component in the pathway of HSF2 activation is labile.

Heat Shock Response and Protein Degradation: Regulation of HSF2 by

Here, we demonstrate that a stress signal for HSF2 activation occurs when the ubiquitin-proteasome pathway is inhibited. ... HSF2 is labile, and its activation requires both continued protein synthesis and reduced degradation.
