This function is crucial for cellular homeostasis because failure to activate ubiquitin, as seen by the chemical inhibition of E1 activity in the cell, results in the almost immediate shutdown of the entire UPS PubMed:24457024
Considering the importance of protein catabolism in maintaining cell homeostasis, it is not surprising that dysregulation of protein turnover is associated with myriad disease states such as cancer and neurodegeneration [5]. PubMed:18930136
These data, in addition to older biochemical studies that empirically used heme to inhibit proteasome function in biochemical assays, led us to the hypothesis that excessive intracellular heme could disrupt cellular protein homeostasis by an inhibitory action on the proteasome. PubMed:25301065
The proteasome is the principal pathway to remove senescent and damaged proteins, and intact proteasome function is essential to preserve and repair cellular homeostasis during oxidative stress, such as that triggered by heme exposure.27 PubMed:25301065
