Cotranslational Protein Translocation01:20

Cotranslational Protein Translocation

8.3K
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.
Sec61 channel partners for cotranslational translocation
During cotranslational translocation, the Sec61 channel partners with the signal recognition particle (SRP), the signal recognition particle receptor (SR), and the ribosomes to transport the nascent polypeptide chain...

Membrane Asymmetry Regulating Transporters01:19

Membrane Asymmetry Regulating Transporters

5.9K
Enzymes like flippase, floppase, and scramblase transfer phospholipids from one layer to another in the membrane, thereby affecting membrane asymmetry.
Flippase
Eukaryotic flippases are type-IV P-type ATPases or P4-ATPases belonging to P-type ATPase family proteins that are membrane-bound pumps involved in the ATP-mediated transport of ions and molecules across the membrane. Flippases flip specific phospholipids from the outer to the inner leaflet of a membrane. All P4-ATPases have one...

Mechanically-gated Ion Channels01:12

Mechanically-gated Ion Channels

6.6K
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...

Repressible Operon: trp Operon

2.7K
The trp operon in Escherichia coli exemplifies a repressible operon. It regulates the synthesis of tryptophan through repressor-mediated transcriptional control and attenuation. This dual regulatory mechanism ensures tryptophan biosynthesis occurs only when needed, conserving cellular resources.Structure of the trp OperonThe trp operon consists of five structural genes (trpE, trpD, trpC, trpB, and trpA) that encode enzymes for tryptophan biosynthesis. These genes are transcribed as a single...

Non-gated Ion Channels01:24

Non-gated Ion Channels

7.3K
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....

Area of Science:

  • Molecular Biology
  • Neuroscience
  • Genetics

Background:

  • Transient Receptor Potential (TRP) channels are a diverse group of cation channels.
  • These channels play vital roles in sensory signaling, detecting stimuli like chemicals, temperature, and mechanical force.

Purpose of the Study:

  • To explore the diverse roles of TRP channels in animal sensory signaling and behavior.
  • To highlight the utility of invertebrate models (C. elegans, D. melanogaster) in understanding TRP channel function.

Main Methods:

  • Utilized genetic models (Caenorhabditis elegans and Drosophila melanogaster) to study TRP channel functions.
  • Analyzed sensory signaling pathways and associated behaviors dependent on TRP channels.

Main Results:

  • TRP channels are involved in a wide array of sensory modalities and behaviors.
  • TRP channels function as multitasking proteins with conserved activation modes across species.
  • Phototransduction, previously thought invertebrate-specific, is conserved in TRP channel function.

Conclusions:

  • Invertebrate models provide valuable insights into the conserved functions of TRP channels.
  • Understanding invertebrate TRP channels can predict and elucidate roles of mammalian TRP channels.
