Encapsulin-associated ferritin proteins form metal-dependent decamers that are active as ferroxidase enzymes, but require encapsulation to form an iron store.
Iron derived from autophagy-mediated ferritin degradation in response to pressure overload induces lipid peroxidation, necrotic cardiomyocyte death, and heart failure in mice.
Human ferritin light chain (FTL) mRNA translation is regulated via its 5'-untranslated region (5'-UTR) by three mechanisms: RNA folding, iron response protein binding, and eukaryotic translation initiation factor eIF3 binding.
Cuticulosomes are organelles found in the hair cells of birds that are composed of ferritin nanoparticles, form rapidly after hatching by the fusion of vesicular structures, and may play an indirect role in magnetic sensation.
Neutrophil pseudopods are composed of multiple sheets that are inherently flat, protrude in three dimensions, and whose assembly correlates with cell turning.
Several new magneto-mechanical and magneto-thermal mechanisms of ion channel activation in magnetogenetics are proposed that may explain some of the mysteries that challenge current understanding of the magnetogenetics experiments.
