Iron Physiology and Its Impact on Atopic Diseases: An EAACI Taskforce Report

Allergy, EarlyView.
ABSTRACT Iron is essential for oxygen transport, energy metabolism, and immune regulation. Yet iron deficiency is the most common micronutrient disorder across all age groups, affecting nearly one quarter of the global population. Iron deficiency triggers nutritional immunity, a host defense mechanism that withholds and redistributes iron, contributing

Leveraging paired germline and somatic analysis to improve the classification of DDX41 variants

British Journal of Haematology, EarlyView.
Summary Constitutional pathogenic variants in DDX41 predispose to myelodysplasia and acute myeloid leukaemia. Acquisition of subsequent somatic hits in the second allele is frequent, with notable recurrent variants at key hotspots. Sequencing of Deoxyribonucleic acid from blood/marrow of 239 patients with suspected/confirmed haematological malignancies

The Sole DEAD-Box RNA Helicase of the Gastric Pathogen Helicobacter pylori Is Essential for Colonization

mBio, 2018
Present in every kingdom of life, generally in multiple copies, DEAD-box RNA helicases are specialized enzymes that unwind RNA secondary structures. They play major roles in mRNA decay, ribosome biogenesis, and adaptation to cold temperatures.

Molecular insights into DNA interference by CRISPR-associated nuclease-helicase Cas3 [PDF]

, 2014
Mobile genetic elements in bacteria are neutralized by a system based on clustered regularly interspaced short palindromic repeats (CRISPRs) and CRISPR-associated (Cas) proteins.

Unwinding the Mechanisms of a DEAD-Box RNA Helicase in Cancer [PDF]

Journal of Molecular Biology, 2015
RNA helicases function in all organisms to manage the conformational states of RNAs of all stripes. The largest family of RNA helicases is the DEAD-box family, with 37 members in humans [1]. DEAD-box proteins interact with and manipulate RNAs that range from rRNAs, as they fold and assemble into ribosomes, to mRNAs as they are exported from the nucleus,

Compartmentalisation in cAMP signalling: A phase separation perspective

British Journal of Pharmacology, EarlyView.
Cells rely on precise spatiotemporal control of signalling pathways to ensure functional specificity. The compartmentalisation of cyclic AMP (cAMP) and protein kinase A (PKA) signalling enables distinct cellular responses within a crowded cytoplasmic space.

Changing nucleotide specificity of the DEAD-box helicase Hera abrogates communication between the Q-motif and the P-loop [PDF]

, 2017
DEAD-box proteins disrupt or remodel RNA and protein/RNA complexes at the expense of ATP. The catalytic core is composed of two flexibly connected RecA-like domains.

Identification and characterisation of transcriptional regulatory proteins that modulate estrogen receptor α activity

, 2009
Breast cancer is the most common malignancy in women in the Western world, accounting for 18% of all female cancers. Two-thirds of breast cancers express Estrogen receptor-α (ERα) and ERα is a predictive and positive prognostic marker.

Host Factors interacting with the Pestivirus N terminal protease, Npro are Components of the Ribonucleoprotein Complex [PDF]

, 2014
The viral N-terminal protease N(pro) of pestiviruses counteracts cellular antiviral defenses through inhibition of IRF3. Here we used mass spectrometry to identify a new role for N(pro) through its interaction with over 55 associated proteins, mainly ...
