Summary
Calmodulin, a calcium-sensor protein, plays a key role in Alzheimer's disease pathology by interacting with proteins involved in amyloid plaque and neurofibrillary tangle formation. Further research into calmodulin's role may yield new therapeutic targets.
Area of Science:
- Neuroscience
- Molecular Biology
- Biochemistry
Background:
- Calmodulin is a ubiquitous calcium-sensor protein vital for cellular functions.
- Alzheimer's disease (AD) is a neurodegenerative disorder characterized by amyloid plaques and neurofibrillary tangles.
- The role of calmodulin in AD pathogenesis is increasingly recognized.
Purpose of the Study:
- To review the existing literature linking calmodulin and its binding proteins to Alzheimer's disease.
- To identify calmodulin-binding proteins involved in key AD pathological hallmarks.
- To discuss the potential of calmodulin as a biomarker and therapeutic target for AD.
Main Methods:
- Literature review of experimentally verified calmodulin-binding proteins in relation to AD.
- Analysis of proteins implicated in amyloid-β plaque and neurofibrillary tangle formation.
- Examination of calmodulin's association with genes identified through genome-wide association studies.
Main Results:
- Multiple calmodulin-binding proteins, including APP, BACE1, PS1, and ADAM10, are implicated in amyloid plaque formation.
- CaMKII, CDK5, and calcineurin are calmodulin-binding proteins associated with neurofibrillary tangles.
- Calmodulin interacts with proteins involved in calcium metabolism (mAchR, NMDAR), neuroinflammation, endocytosis, and apoptosis relevant to AD.
Conclusions:
- Calmodulin is intricately linked to the molecular mechanisms underlying Alzheimer's disease.
- Calmodulin-binding proteins are central to both amyloid plaque and neurofibrillary tangle pathology.
- Calmodulin represents a promising target for future AD biomarker development and therapeutic strategies.

7.2K
Calmodulin (CaM) is a calcium-binding protein in eukaryotes that controls various calcium-regulated cellular processes. It has four calcium-binding sites that bind calcium to form the calcium-calmodulin ( Ca2+-CaM) complex. GPCR stimulation increases the calcium levels in the cells that bind to CaM and induces a conformational change.
The Ca2+-CaM complex does not have enzymatic activity by itself. Instead, the complex binds downstream target proteins, including membrane proteins or enzymes,...

01:26Alzheimer's Disease: Overview
2.0K
Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ...

1.3K
Alzheimer's Disease (AD), a neurodegenerative disorder, is pathologically identified by amyloid plaques and neurofibrillary tangles composed of tau protein. AD pharmacotherapy aims to manage cognitive symptoms, delay disease progression, and treat behavioral symptoms. The treatment is primarily symptomatic and palliative, with no definitive disease-modifying therapy available. Cholinesterase inhibitors, including donepezil (Aricept), rivastigmine (Exelon), and galantamine (Razadyne), are...

01:30Ligand-Gated Ion Channel Receptor: Gating Mechanism
5.0K
Ligand-gated ion channels are transmembrane proteins that play a vital role in intercellular communication and functions of the nervous system. They allow the influx of ions across the membrane once the neurotransmitter binds, allowing the subsequent transmission of electrical excitation across the neurons. Other ligand-gated ion channels, like the γ-aminobutyric acid (GABA) receptor, permit anions like chloride into the cells on the binding of the GABA molecule. Their entry into the cell...

03:03Amyloid Fibrils
13.1K
Amyloid fibrils are aggregates of misfolded proteins. Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils.
Amyloid deposits were observed as early as 1639 in the liver and the spleen. In 1854, Rudolph Virchow performed iodine staining,...

Ligand-gated ion channels are transmembrane proteins with a channel for ions to pass through and a binding site for a ligand. The channel opens only when a ligand attaches to the binding site.
Three Subfamilies of Ligand-gated Ion Channels
Ligand-gated ion channels fall into three subfamilies. The 'Cys-loop' includes the nicotinic acetylcholine receptors, γ-aminobutyric acid (GABA), glycine, and 5-hydroxytryptamine receptors. The second one is the 'Pore-loop' channels that...
