Summary
Cholesterol significantly impacts class C G-protein coupled receptors (GPCRs) by altering their structure and function. This review explores these cholesterol interactions and their therapeutic potential.
Area of Science:
- Biochemistry
- Molecular Biology
- Pharmacology
Background:
- G-protein coupled receptors (GPCRs) are crucial cell-surface proteins involved in numerous physiological processes.
- Cholesterol modulates GPCR structure and function, with imbalances linked to various diseases.
- While Class A GPCRs have been studied, Class C GPCRs' cholesterol interactions remain underexplored.
Purpose of the Study:
- To review the specific sites of interaction between cholesterol and Class C GPCRs.
- To elucidate the functional and structural consequences of cholesterol modulation on Class C GPCRs.
- To explore the therapeutic potential arising from understanding these cholesterol-GPCR relationships.
Main Methods:
- Literature review of existing studies on cholesterol-GPCR interactions.
- Analysis of structural and functional data for Class C GPCRs.
- Synthesis of current research to identify cholesterol recognition sites and effects.
Main Results:
- Cholesterol directly binds to specific sites on Class C GPCRs or indirectly alters the lipid membrane environment.
- These interactions affect the structural features and functional dynamics of Class C GPCRs.
- Specific examples from typical Class C GPCR family members illustrate these effects.
Conclusions:
- Cholesterol plays a significant role in regulating the structure and function of Class C GPCRs.
- Understanding these interactions offers potential avenues for therapeutic interventions.
- Further research into Class C GPCRs and cholesterol is warranted.

01:29Cholesterol: Significance and Regulation
616
Although not a source of energy, cholesterol plays a significant role as a foundational structure for bile salts, steroid hormones, and vitamin D, as well as being a crucial component of plasma membranes. Approximately 15% of blood cholesterol is derived from our diet, with the remainder synthesized from acetyl CoA by the liver and intestines. Cholesterol is eliminated from the body through its conversion into bile salts, which are eventually discarded in the feces.

01:15G Protein-coupled Receptors
12.5K
G Protein-Coupled Receptors or GPCRs are membrane-bound receptors that transiently associate with heterotrimeric G proteins and induce an appropriate response to sensory stimuli such as light, odors, hormones, cytokines, or neurotransmitters.
GPCRs are also called heptahelical, 7TM, or serpentine receptors, and consist of seven (H1-H7) transmembrane alpha-helices that span the bilayer to form a cylindrical core. The transmembrane helices are connected by three extracellular loops and three...

2.1K
G Protein–Coupled Receptors (GPCRs) are membrane-bound receptors that transiently associate with heterotrimeric G proteins and induce an appropriate response to various stimuli. GPCRs regulate critical physiological pathways and are excellent drug targets for treating diseases such as diabetes, cancer, obesity, depression, or Alzheimer's. Nearly 35% of approved drugs implement their therapeutic effects by selectively interacting with specific GPCRs.

01:09GPCRs Regulate Adenylyl Cylase Activity
5.7K
Some GPCRs transmit signals through adenylyl cyclase (AC), a transmembrane enzyme. AC helps synthesize second messenger cyclic adenosine monophosphate (cAMP). AC catalyzes cyclization reaction and converts ATP to cAMP by releasing a pyrophosphate. The pyrophosphate is further hydrolyzed to phosphate by the enzyme pyrophosphatase, which drives cAMP synthesis to completion. However, cAMP is rapidly degraded to 5′ AMP by the enzymes phosphodiesterase (PDE), preventing overstimulation of...

01:25Cholinergic Receptors: Muscarinic
2.5K
The pharmacological actions of acetylcholine are elicited via its binding to two families of cholinergic receptors or cholinoceptors, namely, muscarinic and nicotinic receptors. Muscarinic receptors are G protein-coupled receptors and have five subtypes, M1–M5. All mAChR subtypes are activated by acetylcholine and blocked by the antagonist, atropine.
The subtypes M1, M3, and M5 couple with the Gq subunit and activate the phospholipase C (PLC) activity, mobilizing intracellular Ca2+....

01:22Cholinesterases: Distribution and Function
517
Cholinesterases are a group of serine hydrolase enzymes that play a crucial role in the breakdown of choline esters. The two primary types of cholinesterases are acetylcholinesterases (AChEs) and butyrylcholinesterase (BuChEs), which differ in their distribution, function, and substrate specificity. AChEs, also known as true cholinesterases, specifically hydrolyze acetylcholine, while BuChEs, often referred to as pseudocholinesterases, can hydrolyze various choline esters, including...
