Summary
Chemosensory receptors (CRs) detect chemical cues, but their structures are hard to study. This review highlights how in silico methods advance understanding of vertebrate CR structures.
Area of Science:
- Biochemistry
- Structural Biology
- Neuroscience
Background:
- Chemical communication relies on diverse chemical cues perceived by chemosensory receptors (CRs).
- CRs, part of the G-protein-coupled receptor (GPCR) family, share conserved seven-transmembrane (7TM) α-helical structures.
- Studying CR structures is challenging due to protein characteristics and traditional methods.
Purpose of the Study:
- To review current knowledge of vertebrate chemosensory receptors (CRs).
- To emphasize the application of in silico structural biology methods for CR studies.
- To explore how computational approaches overcome structural resolution limitations.
Main Methods:
- Review of existing literature on vertebrate CRs.
- Focus on in silico structural biology techniques and algorithms.
- Analysis of computational methods applied to CR structure determination.
Main Results:
- Vertebrate CRs exhibit conserved GPCR structures.
- In silico methods offer powerful alternatives for CR structural analysis.
- Advancements in algorithms since the 1960s have improved structural predictions.
Conclusions:
- In silico structural biology is crucial for understanding CRs, especially olfactory and taste receptors.
- Computational approaches are vital for overcoming experimental limitations in CR structure determination.
- Further development of in silico methods will enhance insights into CR function and signaling.

01:26Introduction to Special Senses
6.2K
Sensory receptors play an integral part in comprehending our external and internal environments. They receive diverse stimuli, converting them into the nervous system's electrochemical signals. This conversion occurs as the stimulus alters the sensory neuron's cell membrane potential, instigating the generation of an action potential. This action potential is subsequently transmitted to the central nervous system (CNS), which integrates with other sensory data or higher cognitive...

01:25Olfaction
45.2K
The sense of smell is achieved through the activities of the olfactory system. It starts when an airborne odorant enters the nasal cavity and reaches olfactory epithelium (OE). The OE is protected by a thin layer of mucus, which also serves the purpose of dissolving more complex compounds into simpler chemical odorants. The size of the OE and the density of sensory neurons varies among species; in humans, the OE is only about 9-10 cm2.

01:03Olfactory Receptors: Location and Structure
9.6K
The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...

01:27Tactile and Chemical Senses
361
Tactile senses encompass touch, temperature, and pain, each mediated by specific receptors. Touch receptors detect mechanical energy or pressure against the skin. Sensory fibers from these receptors enter the spinal cord and relay information to the brain stem. Here, most fibers cross over to the opposite side of the brain. The touch information then moves to the thalamus, which projects a map of the body's surface onto the somatosensory areas of the parietal lobes in the cerebral cortex.

01:15G Protein-coupled Receptors
13.5K
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...

01:31Introduction to Sensory Receptors
4.0K
Sensory receptors are vital in our ability to perceive and interpret the world. Sensory receptors are specialized cells in the peripheral nervous system that respond to various stimuli and enable one to experience different sensations. Based on specific criteria, sensory receptors are classified into distinct types.
The first classification criterion is based on cell type, position, and function. Some receptor cells are neurons with free nerve endings, where their dendrites are embedded in the...
