Peptidases/ proteases may possibly generally be topic to damaging regulation by ASK1-E3s, thus coupling peptidase-mediated protein processing or degradation with the UPS.Feasible strategies that ASK1 regulates gene expressionFig. 7 Possible mechanisms of transcriptome and proteome regulations by ASK1-E3s. a ASK1-E3s may regulate gene transcription by destabilizing transcription aspects. The transcription variables are stabilized in ask1 mutant and activate or repress downstream gene transcription. TF+, transcriptional activators; TF-, transcriptional repressors. b ASK1-E3s may possibly destabilize substrate X, which positively regulates the abundance of target proteins Y. Within the ask1 mutant proteome, ASK1-E3 substrate X and their target protein Y accumulate. c ASK1-E3s could possibly destabilize substrate X, which negatively regulates the abundance of target protein Y. In the ask1 mutant proteome, ASK1-E3 substrate X accumulates but target protein Y decreases. Bars, negative regulation; horizontal arrows, optimistic regulation; dashed gray bars and horizontal arrows, missing regulations; upward arrows, improve in abundance; downward arrows, reduce in abundanceBy integrative evaluation of transcriptome and proteome data, we discovered that ASK1-E3s could regulate gene expression at a number of actions, ranging from transcriptional, translational, to post-translational regulations. ASK1-E3s may possibly destabilize transcription repressors or activators to derepress or inactivate gene transcription, respectively (Fig. 7a). In the absence of ASK1, the accumulation of these transcriptional repressors or activators final results in down-regulation or upregulation of gene transcription, respectively. On the other hand, we cannot rule out the possibility that the altered transcriptome and proteome may possibly be indirect consequences of your ask1 mutation. The proteins accumulated in ask1 may possibly be direct substrates of ASK1-E3s, or stabilized by ASK1-E3 title= jir.2013.0113 substrates (Fig. 7b). One example is, ubiquitin-specific proteases UBP5 and UBP6, which accumulate in the ask1 proteome (Table 7), could be substrates of ASK1-E3s; UBP5 and UBP6 could deubiquitinate and stop degradation of ubiquitinated proteins, whose protein levels are then improved in ask1. An example in human could be the herpesvirusassociated ubiquitin-specific protease (HAUSP), whichstabilizes a tumor suppressor p53 by deubiquitination [81]. Ribosomal proteins could share a related mechanism: accumulation of ribosomal proteins in ask1 may possibly enhance protein synthesis; alternatively, if ribosomal proteins have extraribosomal regulatory functions, they might stabilize some proteins within a similar way as those stabilizing p53 in human [67]. In a different doable situation, ASK1-E3s may destabilize some proteolytic enzymes (e.g., E3 ubiquitin ligases orLu et al. BMC Plant Biology (2016) 16:Page 13 ofpeptidases), which can degrade other proteins (Fig. 7c), forming a double unfavorable regulation cascade. The accumulation of such proteolytic enzymes in ask1 may perhaps bring about decreased levels of their proteolytic substrates.
