Disassembly is thought to be mediated in several ways, including by changes in tension and posttranslational modifications or by proteolytic cleavage of critical adhesion components (16– 16).
The percent modification of each residue following hydroxyl radical-mediated modification was determined by proteolytic cleavage of the peptide and LC MS analysis.
These proteins were absent in the ago2-1 mutant plants indicating that they represent isoforms of AGO2 due possibly to posttranslational modification or cleavage by proteolytic enzymes.
This modification is followed by proteolytic cleavage within the CAAX motif and carboxymethylation of the exposed cysteine residue.
In addition, in vitro studies have supported a loss of function of Beclin-1 due to proteolytic modification by caspases.
Third, post-translational modifications of the Cav1.2 LTCC protein by proteolytic cleavage of the C-terminus region can significantly impact voltage-dependent activation and activity of the channel (Wei et al., 1994; Hulme et al., 2006).
Apart from translocation based activation, NF-κB can be regulated by proteolytic procession or posttranslational modifications like HDAC mediated acetylation or deacetylation, suggesting a potential RelA/p65 inhibitory effect of HDIs like SAHA and VPA [ 20].
We hypothesized that PSV-associated preservation of respiratory muscle activity would induce less diaphragmatic catabolic damage as shown by modifications of proteolytic and protein synthesis activities and oxidative injury.
Furthermore, other AMPs should be evaluated as potential performance enhancers and chemical modification or encapsulation methods should be evaluated to prevent degradation by proteolytic enzymes within the digestive system of production animals [ 6].
In particular the use of the protein fingerprint technology, that identifies neo-epitopes of ECM proteins generated by proteolytic cleavage by proteases or other post-translational modifications, might identify such novel biomarkers of renal fibrosis.
