Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

open access: yesFEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

Recovery from smell loss [PDF]

open access: yes, 2021
Loss or impaired sense of smell is a symptom of viral illnesses, including the common cold (Pellegrino et al., 2017) and SARS-CoV-2 (Gerkin et al., 2020; Pellegrino et al., 2020), sinonasal disease (Dalton, 2004), traumatic brain injury (Collet et al ...

Olfactory threshold and odor discrimination ability in children – evaluation of a modified “Sniffin’ Sticks” test

open access: yesScientific Reports, 2017
The clinical diagnostics of olfactory dysfunction in children turns out to be challenging due to low attention span, insufficient linguistic development and lack of odor experiences. Several smell tests have been developed for adults.

Clivus Rathke cleft cyst: case report of a rare disease and literature review [PDF]

open access: yesRhinology Online, 2018
Background: Rathke's cleft cysts (RCCs) are nonneoplastic epithelial lesions derived from true remnants of the embryological Rathke's pouch. They are commonly located in the sellar and suprasellar region and usually appear as an asymptomatic mass. Case:

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

More than smell - COVID-19 is associated with severe impairment of smell, taste, and chemesthesis [PDF]

open access: yes, 2020
Recent anecdotal and scientific reports have provided evidence of a link between COVID-19 and chemosensory impairments, such as anosmia. However, these reports have downplayed or failed to distinguish potential effects on taste, ignored chemesthesis, and

Altered functional properties of the codling moth Orco mutagenized in the intracellular loop-3

open access: yesScientific Reports, 2021
Amino acid substitutions within the conserved polypeptide sequence of the insect olfactory receptor co-receptor (Orco) have been demonstrated to influence its pharmacological properties.

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

SMELL [PDF]

open access: yes, 2023
Although somewhat marginal in relation to the other senses, smell is the most potent way of anchoring ourselves to the world. We subconsciously find our place in it by sniffing our body, the body of the one next to us, the room in which we are, the ...

Interpreting the effects of DNA polymerase variants at the structural level

open access: yesMolecular Oncology, EarlyView.
Using MAVISp and molecular dynamics simulations, we analyzed over 60 000 missense variants in POLE and POLD1 from ClinVar, COSMIC, cBioPortal, and saturation mutagenesis. Identified mechanistic indicators, including stability, binding, and long‐range, enable structural interpretation, providing ACMG‐like evidence for possible reclassification of VUS ...
