Insights

New Parkinson's disease (PD) therapies focus on allosteric LRRK2 inhibitors. This approach bypasses safety concerns of current ATP-competitive drugs, offering a promising alternative for treating this neurodegenerative disease.

Area of Science:

  • Neuroscience
  • Pharmacology
  • Genetics

Background:

  • Parkinson's disease (PD) is a prevalent neurodegenerative disorder.
  • Leucine-rich repeat kinase 2 (LRRK2) plays a key role in both familial and sporadic PD.
  • Pathogenic LRRK2 mutations increase its kinase activity, making it a therapeutic target.

Purpose of the Study:

  • To review recent advancements in developing allosteric LRRK2 inhibitors.
  • To explore alternative strategies for targeting LRRK2 activity beyond ATP-competitive inhibition.
  • To identify novel intra- and interprotein interaction targets for PD therapeutics.

Main Methods:

  • Review of current literature on LRRK2 inhibitors.
  • Analysis of allosteric inhibition mechanisms, focusing on GTPase activity.
  • Identification of potential new therapeutic targets within LRRK2 pathways.

Main Results:

  • Development of selective LRRK2 inhibitors with brain availability.
  • Concerns regarding the long-term safety of ATP-competitive LRRK2 inhibitors.
  • Emergence of allosteric inhibition as a viable therapeutic strategy.

Conclusions:

  • Allosteric LRRK2 inhibitors offer a safer alternative to ATP-competitive drugs.
  • Targeting LRRK2's GTPase activity is a promising therapeutic avenue.
  • Further research into LRRK2 interactions may unlock new PD treatments.

Allosteric Regulation01:08

Allosteric Regulation

Allosteric regulation of enzymes occurs when the binding of an effector molecule to a site that is different from the active site causes a change in the enzymatic activity. This alternate site is called an allosteric site, and an enzyme can contain more than one of these sites. Allosteric regulation can either be positive or negative, resulting in an increase or decrease in enzyme activity. Most enzymes that display allosteric regulation are metabolic enzymes involved in the degradation or...

Allosteric Proteins-ATCase

Binding sites linkages can regulate a protein's function.  For example, enzyme activity is often regulated through a feedback mechanism where the end product of the biochemical process serves as an inhibitor.
Aspartate transcarbamoylase (ATCase) is a cytosolic enzyme that catalyzes the condensation of L-aspartate and carbamoyl phosphate to  N-carbamoyl-L-aspartate. This reaction is the first step in pyrimidine biosynthesis. UTP and CTP, the end products of the pyrimidine synthesis...

Cooperative Allosteric Transitions01:58

Cooperative Allosteric Transitions

Cooperative allosteric transitions can occur in multimeric proteins, where each subunit of the protein has its own ligand-binding site. When a ligand binds to any of these subunits, it triggers a conformational change that affects the binding sites in the other subunits; this can change the affinity of the other sites for their respective ligands. The ability of the protein to change the shape of its binding site is attributed to the presence of a mix of flexible and stable segments in the...

Ligand Binding and Linkage00:49

Ligand Binding and Linkage

Allosteric proteins have more than one ligand binding site; the binding of a ligand to any of these sites influences the binding of ligands to the other sites. When a protein is allosteric, its binding sites are called coupled or linked.  In the case of enzymes, the site that binds to the substrate is known as the active site and the other site is known as the regulatory site. When a ligand binds to the regulatory site, this leads to conformational changes in the protein that can influence...
