    Insights

    Neuroprotector NT-1505 does not significantly alter endoplasmic reticulum membrane structure. Studies show its effects on microviscosity are temporary, indicating no pathological disturbances.

    Area of Science:

    • Biochemistry
    • Cell Biology
    • Neuroscience

    Context:

    • Endoplasmic reticulum (ER) membranes are crucial for protein folding and lipid synthesis.
    • Neuroprotectors are investigated for their potential to preserve neuronal function.
    • Understanding drug interactions with cellular membranes is vital for therapeutic development.

    Purpose:

    • To investigate the impact of neuroprotector NT-1505 on the structural dynamics of endoplasmic reticulum (ER) membranes.
    • To assess whether NT-1505 induces pathological changes in ER membrane microviscosity.
    • To characterize the temperature-dependent structural transitions of ER membranes under NT-1505 influence.

    Summary:

    • Neuroprotector NT-1505 was evaluated for its effects on ER membrane microviscosity using electron paramagnetic resonance spin labeling with lipid and near-protein probes.
    • Measurements of temperature-dependent rotational diffusion correlation times revealed that NT-1505 administration resulted in temporary, non-pathological changes in membrane microviscosity.
    • The characteristic temperature-dependent structural transitions observed in control ER membranes remained present after NT-1505 treatment, indicating no significant structural alterations.

    Impact:

    • This study suggests that NT-1505 does not induce significant structural damage to ER membranes.
    • Findings contribute to the safety profile assessment of NT-1505 as a potential neuroprotective agent.
    • The research provides insights into the interaction of NT-1505 with cellular membrane components.

    Tail-anchoring of Proteins in the ER Membrane

    Tail-anchored, or TA, proteins are estimated to make up to 3-5% of membrane proteins found in the eukaryotic cell. Such proteins have a single transmembrane domain located approximately 30 amino acid residues upstream from the C-terminal end. As a result, the signal recognition particle (SRP) cannot guide a TA protein to the ER membrane for cotranslational insertion. Hence, they are integrated into the ER membrane post-translationally using their C-terminal end as the anchor. TA proteins...

    The Endoplasmic Reticulum01:43

    The Endoplasmic Reticulum

    The endoplasmic reticulum or ER makes up for more than half of the membranes in a cell and accounts for 10% of total cell volume. It is also the primary protein and lipid synthesis factory for most cell organelles, such as the Golgi apparatus, lysosomes, secretory vesicles, and the plasma membrane. Despite being the most extensive and functionally complex subcellular organelle, ER was the last to be discovered. After years of deliberation, Keith Porter and George Palade in the year 1954,...

    Insertion of Single-pass Transmembrane Proteins in the RER

    Integral membrane proteins are proteins adhered to the lipid bilayer of a cell organelle or membrane. They can be of two types: transmembrane integral proteins that span the lipid bilayer and monotopic proteins that are attached to either side of the membrane but do not pass through it.
    Integral transmembrane proteins possess transmembrane and extra membrane domains. The transmembrane domains are primarily made of 20-25 hydrophobic amino acids arranged in a helical secondary confirmation. These...

    Directing Proteins to the Rough Endoplasmic Reticulum

    The organelle-specific signaling sequences direct proteins synthesized in the cytosol to their final destination like ER, mitochondria, peroxisomes, etc. Some of the proteins directed to ER are then trafficked via vesicles to other organelles within the cell or the extracellular environment through the Golgi complex. For example, the rough ER synthesizes soluble proteins for transportation to the lysosomes or secretion out of the cell. It can also synthesize transmembrane proteins that can...

    Endoplasmic Reticulum

    The Endoplasmic Reticulum (ER) in eukaryotic cells is a substantial network of interconnected membranes with diverse functions, from calcium storage to biomolecule synthesis. A primary component of the endomembrane system, the ER manufactures phospholipids critical for membrane function throughout the cell. Additionally, the two distinct regions of the ER specialize in the manufacture of specific lipids and proteins.

    Post-translational Translocation of Proteins to the RER01:27

    Post-translational Translocation of Proteins to the RER

    A sizable fraction of proteins destined for ER are first synthesized in the cell cytosol and then transported across the ER membrane–a process called post-translational translocation. Similar to cotranslationally translocated proteins, these proteins also use the Sec translocon complex to enter the ER lumen.
    Targeting proteins to the ER
    Hsp40 and Hsp70 chaperone molecules bind the translated proteins in the cytosol to prevent their folding. The chaperone binding helps to keep the signal...
