Insights

This study reports the first NMR chemical shift assignments for short-form cellular FLICE-inhibitory protein (c-FLIPS). These findings are crucial for understanding the molecular mechanisms behind c-FLIPS

Area of Science:

  • Molecular Biology
  • Biochemistry
  • Structural Biology

Background:

  • Cellular FLICE-inhibitory protein (c-FLIP) regulates apoptosis via the extrinsic cell death pathway.
  • c-FLIP exists in splice variants, including short (c-FLIPS) and long (c-FLIPL) forms.
  • The death-inducing signaling complex (DISC) controls apoptosis and programmed necrosis, with c-FLIP regulating its assembly and activation.

Purpose of the Study:

  • To determine the NMR chemical shift assignments for the short-form of cellular FLICE-inhibitory protein (c-FLIPS).
  • To provide foundational structural data for future investigations into c-FLIPS's anti-apoptotic functions.

Main Methods:

  • Nuclear Magnetic Resonance (NMR) spectroscopy was employed.
  • Chemical shift assignments for c-FLIPS were obtained.

Main Results:

  • Complete NMR chemical shift assignments for c-FLIPS were successfully determined.
  • This provides essential data for understanding the protein's structure and function.

Conclusions:

  • The reported NMR assignments for c-FLIPS are a significant step.
  • This structural information will facilitate research into the molecular basis of c-FLIPS's anti-apoptotic activity.

Protein Folding

Proteins are chains of amino acids linked together by peptide bonds. Upon synthesis, a protein folds into a three-dimensional conformation, critical to its biological function. Interactions between its constituent amino acids guide protein folding, and hence the protein structure is primarily dependent on its amino acid sequence.
Protein Structure Is Critical to Its Biological Function
Proteins perform a wide range of biological functions such as catalyzing chemical reactions, providing...

Intrinsically Disordered Proteins

Intrinsically disordered proteins are a group of proteins that do not fold into specific three-dimensional structures. Their structural flexibility allows them to complement ordered proteins to perform functions that are inaccessible to rigid structures. They are more common in eukaryotes than prokaryotes and may either be exclusively intrinsically disordered or hybrid proteins, consisting of a mix of ordered and disordered regions. The absence of a rigid structure in these proteins can be...

Membrane Asymmetry Regulating Transporters

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...
