Protein Dynamics in Living Cells01:19

Protein Dynamics in Living Cells

2.3K
Different fluorescence-based techniques are used to study the protein dynamics in living cells. These techniques include FRAP, FRET, and PET.
Fluorescent recovery after photobleaching (FRAP) is a fluorescent-protein-based detection technique used to quantify protein movement rates within the cell. This method exposes a small portion of the cell to an intense laser beam. The laser beam causes permanent photobleaching of the fluorophore-tagged proteins in the exposed region. As the bleached...

Protein-protein Interfaces

14.0K
Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs are stabilized by numerous weak noncovalent chemical forces. The physical shape of the interfaces determines the way two proteins interact. Many globular proteins have closely-matching shapes on their surfaces, which form a large number of weak bonds. Additionally, many PPIs occur between two helices or between a surface cleft and a...

Protein Networks

4.1K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Protein-Drug Binding: Mechanism and Kinetics

1.2K
Protein-drug binding refers to the interaction between drugs and proteins within the body. This binding process can occur intracellularly, involving drug interactions with enzymes or receptors within cells, or extracellularly, involving plasma proteins in the blood.
Various forces drive these interactions, including hydrogen bonds, hydrophobic interactions, ionic bonds, electrostatic interactions, and van der Waals forces. These bonds enable drugs to bind to specific sites on proteins,...

Antiepileptic Drugs: Modulators of Neurotransmitter Release Mediated by SV2A Protein

510
Antiepileptic drugs, such as levetiracetam (Keppra) and brivaracetam (Briviact), have emerged as crucial tools in managing epilepsy. These medications exert their therapeutic effects by targeting the synaptic vesicle protein SV2A, a transmembrane glycoprotein primarily found in the brain.
SV2A is a transmembrane glycoprotein located predominantly in the brain, modulating the release of neurotransmitters for neuronal communication. Both levetiracetam and brivaracetam exhibit a high affinity for...

Background:

  • The transcriptional regulator EVI1, encoded by the MECOM locus, is a potent oncogenic driver in acute myeloid leukemia (AML).
  • High EVI1 expression is strongly associated with aggressive disease and poor prognosis in AML patients.
  • Mechanisms underlying EVI1's role in leukemogenesis and therapeutic resistance are under active investigation.

Purpose of the Study:

  • To review and discuss the protein interactions of EVI1 and its isoforms, MDS-EVI1 and ΔEVI1.
  • To explore the therapeutic potential of targeting EVI1-mediated pathways in AML.
  • To synthesize recent findings on EVI1's genetic activation and downstream effects.

Main Methods:

  • Literature review of recent clinical and experimental studies.
  • Analysis of published data on EVI1 protein-protein interactions.
  • Discussion of genetic mechanisms and downstream events of EVI1 overexpression.

Main Results:

  • Recent discoveries illuminate genetic mechanisms activating EVI1 overexpression.
