Targeted Protein Modification (TPM) uses bifunctional agents to alter proteins. Novel TPM strategies beyond degradation offer precise therapeutic potential but require further development for clinical use.
Area of Science:
- Biochemistry
- Molecular Biology
- Drug Discovery
Background:
- Targeted Protein Modification (TPM) encompasses techniques using bifunctional agents to modify target proteins.
- PROTAC-directed protein ubiquitination is a prominent TPM strategy, revolutionizing drug discovery with several PROTACs in clinical trials.
Purpose of the Study:
- To explore novel Targeted Protein Modification strategies beyond degradation.
- To investigate the advantages and disadvantages of emerging TPM approaches.
- To discuss the potential applications of these innovations in various diseases.
Main Methods:
- Review of recent advancements in Targeted Protein Modification.
- Analysis of novel strategies including phosphorylation, acetylation, and O-GlcNAcylation.
- Exploration of pros and cons of these emerging techniques.
Main Results:
- TPM has evolved beyond protein degradation to include other modifications like phosphorylation and acetylation.
- These novel strategies offer precise outcomes with minimized side effects.
- The field is nascent, with significant potential but requiring further clinical translation.
Conclusions:
- Emerging TPM strategies offer new therapeutic avenues.
- Further research is needed to overcome limitations and facilitate clinical application.
- TPM innovations hold promise for treating cancer, neurodegenerative, viral, and autoimmune diseases.

01:26Targets for Drug Action: Overview
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...

Drugs can be agonists or antagonists. Like the endogenous ligands, agonists always bind and activate the target to produce a cellular response. Agonist binding induces a conformational change which in turn...
