What Is PROTAC Technology? Proteolytic targeting chimera (PROTAC) is a new type of drug design technology that works by inducing the degradation of target proteins. Unlike conventional small molecules that typically inhibit protein function, PROTACs facilitate the ubiquitination and subsequent degradation of specific proteins. This bifunctional molecule consists of two distinct elements: a ...
Ubiquitination is a post-translational modification process that involves various biological processes, including signal transduction, cell cycle regulation, cell stress responses, and cell apoptosis. It plays a crucial role in maintaining protein homeostasis, regulating various biological reactions in cells, and ensuring the normal physiological functions of organisms. Immunoprecipitation is a ...
Therefore, measuring the ubiquitination level of a protein is significant for understanding its function and regulation mechanism. This article mainly introduces how to detect the ubiquitination level of a protein.ImmunoblottingImmunoblotting is a common method for detecting the level of ...
Western blot can accurately detect the presence and expression of specific proteins in samples, and it can also be used to detect protein post-translational modifications, such as phosphorylation, ubiquitination, etc. ...
Commonly Used Ubiquitinated Protein Enrichment Methods1. Ubiquitin Antibody EnrichmentThis is one of the most common methods for enriching ubiquitinated proteins. Researchers use high-affinity ubiquitin antibodies to bind to ubiquitinated proteins, then use methods such as immunoprecipitation or affinity chromatography to bind the ubiquitinated proteins to the antibodies, which can then be used ...
Protein Ubiquitination is a crucial cellular biological process. It involves the binding of Ubiquitin protein to the target protein, thereby regulating the degradation, positioning, activation, etc., of the target protein. ...
Post-translational modification (PTM) refers to the biochemical process where specific amino acid residues of a protein are chemically modified after its translation. These chemical modifications greatly expand the functional diversity of proteins, enabling them to participate in more cellular physiological processes. The following are some common post-translational modifications of proteins:1. ...
Tau protein is a microtubule-associated protein, mainly present in nerve cells, and participates in the stabilization of microtubules. In certain neurodegenerative diseases, such as Alzheimer's disease (AD), Tau protein may undergo abnormal phosphorylation and aggregation, forming so-called Tau tangles or neurofibrillary tangles.Ubiquitination is a kind of post-translational modification of ...
Co-immunoprecipitation (Co-IP) is an experimental technique used to detect the interaction between a protein and other proteins. When it comes to detecting protein ubiquitination, Co-IP can be used to determine whether the target protein is ubiquitinated, and its interaction with ubiquitin protein.Analysis Workflow1. Sample PreparationCollect cellular or tissue samples, and lyse the cells with ...
In post-translational modification (PTM) of proteins, ubiquitination is considered one of the most critical processes in regulating cellular functions and various diseases. The identification of ubiquitination sites becomes very crucial for understanding the mechanisms of ubiquitination-related biological processes. Experimental and computational methods can be used to identify ubiquitination ...
Histone modification is an important epigenetic regulatory mechanism, achieved by adding or removing various chemical groups to specific amino acid residues on histones. These modifications can influence the structure and function of chromatin, thereby regulating gene expression. To date, at least nine different types of histone modifications have been discovered. Acetylation, methylation, ...
Ubiquitination detection of proteins is a biochemical technique used to identify and analyze ubiquitination modifications on proteins. Ubiquitination is a post-translational modification process that involves the covalent linkage of the small protein ubiquitin to lysine residues of a target protein, a modification that plays a crucial role in the regulation of protein degradation, signal ...
The ubiquitination site of a protein refers to those specific amino acid residues on the protein molecule that can covalently bind with Ubiquitin. Ubiquitin is a small protein that plays an important regulatory role in cells, particularly in protein degradation and signal transduction. Ubiquitination is a post-translational modification process where ubiquitin molecules are attached to specific ...
Post-translational modifications (PTMs) of histones are crucial for protein structure regulation, playing key roles in gene expression regulation, DNA repair, cell signaling, and more. These PTMs of histones can be achieved by adding or removing different chemical groups or proteins, thus affecting chromatin structure and function. Here are some common types of histone PTMs. 1. Acetylation The ...
Proteolysis Targeting Chimeras (PROTACs) are a novel approach for degrading target proteins. Recently, a new split-and-mix PROTAC (SM-PROTAC) system based on liposome self-assembly, known as LipoSM-PROTAC, was reported in the Journal of the American Chemical Society. The LipoSM-PROTAC system exhibits selective degradation of target proteins, with folate serving as a key ligand. In this study, the ...
In cells, PROTAC molecules can recognize and selectively bind target proteins, recruit specific E3 ubiquitin ligases, and form a “target protein-PROTAC-E3 ubiquitin ligase” ternary complex. Afterwards, E3 ubiquitin ligase and E2 ubiquitin conjugating enzyme work together to ...
In this study, the research team constructed the PROTAC virus to reduce the replication ability of the virus by manipulating the degradation of viral proteins and attenuated the wild-type virus into a vaccine.
