Structural dynamics of the plant hormone receptor ETR1 in a native‐like membrane environment

FEBS Letters, EarlyView.
The present study unveils the structural and signaling dynamics of ETR1, a key plant ethylene receptor. Using an optimized nanodisc system and solution NMR, we captured full‐length ETR1 in a native‐like membrane environment. Our findings reveal dynamic domain uncoupling and Cu(I)‐induced rigidification, providing the first evidence of metal‐triggered ...

Axion predictions in SO(10) × U(1)PQ models

Journal of High Energy Physics, 2018
Non-supersymmetric Grand Unified SO(10) × U(1)PQ models have all the ingredients to solve several fundamental problems of particle physics and cosmology — neutrino masses and mixing, baryogenesis, the non-observation of strong CP violation, dark matter ...

Magnetogenesis from a rotating scalar: à la scalar chiral magnetic effect

Journal of High Energy Physics, 2020
The chiral magnetic effect (CME) is a phenomenon in which an electric current is induced parallel to an external magnetic field in the presence of chiral asymmetry in a fermionic system.

TBA [PDF]

Proceedings of Corfu Summer Institute on Elementary Particle Physics — PoS(corfu98), 1999
We start with a brief presentation of the Standard Model and the weak neutral current, in view of a discussion of parity-violation in electron-hadron electroweak interactions. We then discuss some limitations of this model, motivating the consideration of larger frameworks such as grand-unification and supersymmetry.

Protein kinase FAM20C—when subcellular localization matters

FEBS Letters, EarlyView.
FAM20C is a Golgi‐resident kinase that phosphorylates proteins along the entire secretory pathway. The presence of potential FAM20C substrates in the cytoplasm or nucleus raises the question of how the kinase and its substrates encounter each other. Protein kinases achieve signaling specificity through consensus sequence recognition and subcellular ...

Road map through the desert: unification with vector-like fermions

Journal of High Energy Physics, 2019
In light of null results from New Physics searches at the LHC, we look at unification of the gauge couplings as a model-building principle. As a first step, we consider extensions of the Standard Model with vector-like fermions.

Running of fermion observables in non-supersymmetric SO(10) models

Journal of High Energy Physics, 2018
We investigate the complete renormalization group running of fermion observables in two different realistic non-supersymmetric models based on the gauge group SO(10) with intermediate symmetry breaking for both normal and inverted neutrino mass orderings.

Gravitational wave and CMB probes of axion kination

Journal of High Energy Physics, 2022
Rotations of an axion field in field space provide a natural origin for an era of kination domination, where the energy density is dominated by the kinetic term of the axion field, preceded by an early era of matter domination.

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

FEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Hadron collider sensitivity to fat flavourful Z ′s for R K ∗ $$ {R}_{K^{\left(\ast \right)}} $$

Journal of High Energy Physics, 2019
We further investigate the case where new physics in the form of a massive Z ′ particle explains apparent measurements of lepton flavour non-universality in B → K (*) l + l − decays.
