WebAug 24, 2024 · Cysteine oxidative modification of cellular proteins is crucial for many aspects of cardiac hypertrophy development. However, integrated dissection of multiple types of cysteine oxidative post-translational modifications (O-PTM) of proteomes in cardiac hypertrophy is currently missing. WebJul 29, 2024 · Muscle actins, typically containing a Cys in the second position, are processed by Met-AP1/2 to remove the N-terminal Met, followed by Cys acetylation, likely by NatA, and acetylated Cys removal by ANAP, to expose the acidic residue in …
WebOne of the proposed mechanisms involves the posttranslational modification of protein cysteine residues, a process called S-sulfhydration. In this work, a modified biotin switch method was used for the detection of Arabidopsis (Arabidopsis thaliana) proteins modified by S-sulfhydration under physiological conditions. WebThese modifications modulate protein activity, structure, location and interactions, and, thereby, control many core biological processes. Aberrant post-translational …
WebMay 4, 2014 · Protein ubiquitination is an important post-translational modification involved in several essential signalling pathways. It has different effects on the target protein substrate, i.e., it can trigger the degradation of the protein in the proteasome, change the interactions of the modified protein with its partners, or affect its localization and activity. … WebSelected Milestones in Histone Post-Translational Modification (PTM) Discovery. ... Cysteine residues have sulfur-containing thiol side chains that attack electrophilic species, including molecules with carboxylic acid substituents, such as palmitic acid .
