Insights

Transient receptor potential (TRP) channels are versatile cation channels found in many organisms. These channels play crucial roles in sensing the environment and are implicated in various human diseases when malfunctioning.

Area of Science:

  • Molecular Biology
  • Physiology
  • Biophysics

Context:

  • Transient receptor potential (TRP) channels represent a diverse superfamily of non-selective cation channels.
  • These channels are conserved across species, from yeast to mammals, highlighting their fundamental biological importance.
  • TRP channels are classified into seven distinct groups based on structural homology: TRPC, TRPV, TRPM, TRPP, TRPML, TRPA, and TRPN.

Purpose:

  • To provide a comprehensive overview of the TRP channel superfamily.
  • To detail the structural classification, functional properties, and activation mechanisms of TRP channels.
  • To underscore the physiological significance and pathological relevance of TRP channels.

Summary:

  • TRP channels are functionally versatile, non-selective cation channels subdivided into seven groups.
  • They are generally weakly voltage-dependent and activated by diverse stimuli including ligands, compounds, heat, and pH.
  • Found in numerous cell types, TRP channels are vital for sensory perception and environmental sensing.

Impact:

  • TRP channels are essential for animals to perceive external stimuli and for cells to sense their local environment.
  • Dysfunction or mutations in TRP channels are linked to a significant role in the pathogenesis of several human diseases.
  • Understanding TRP channel biology offers potential therapeutic targets for a range of diseases.

Thermosensation01:43

Thermosensation

Peripheral thermosensation is the perception of external temperature. A change in temperature (on the surface of the skin and other tissues) is detected by a family of temperature-sensitive ion channels called Transient Receptor Potential, or TRP, receptors. These receptors are located on free nerve endings. Those detecting cold temperatures are closer to the surface of the skin than the nerve endings detecting warmth. These thermoTRP channels, while temperature selective, have relatively...
Mechanically-gated Ion Channels01:12

Mechanically-gated Ion Channels

Mechanically-gated ion channels are proteins found in eukaryotic and prokaryotic cell membranes that open in response to mechanical stress. Tension, compression, swelling, and shear stress can alter the conformation of the protein, opening a transmembrane channel that allows the passage of ions for signal transmission. In eukaryotes, mechanically-gated channels are distributed in several regions like the neurons, lungs, skin, bladder, and heart, where they play critical roles in numerous...

Cotranslational Protein Translocation

Translocation of proteins across membranes is an ancient process that occurs even in bacteria and archaebacteria. In fact, the components of the translocation machinery are still conserved between prokaryotes and eukaryotes.

G-Protein Gated Ion Channels01:21

G-Protein Gated Ion Channels

GPCRs are primarily responsible for our sense of smell, taste, and vision.  The binding of a sensory stimulus activates GPCR to stimulate effector proteins, many of which are ion channels in the sensory organs. GPCRs modulate the opening and closing of the target ion channels either directly by binding them, or by releasing second messengers that activate these channels. As ions move across the membrane, the membrane potential is altered, which induces an appropriate response.
Sensory organs,...
Non-gated Ion Channels01:24

Non-gated Ion Channels

Ion channels are specialized proteins on the plasma membrane that allow charged ions to pass down their electrochemical gradient. Their main function is to maintain the membrane potential which is critical for cell viability. These channels are either gated or non-gated and can transport more than a thousand ions within milliseconds for the cellular event to occur.
Compared to the gated ion channels, the non-gated channels, also known as leakage or passive channels, have no gating mechanism.
