In some cases, these tags double as affinity tags, not only facilitating soluble expression but also increasing the efficiency of protein purification
P53 phosphorylation at Ser15 was confirmed to enhance the affinity for both FOXO4 and FOXO4-DRI, providing a structural explanation for FOXO4-DRIs preferential engagement with the hyperphosphorylated p53 that characterises senescent cells
Foods rich in Vitamin C include oranges, strawberries, kiwi, bell peppers, and lemons
Higher HRV signals a nervous system that can shift out of stress and back into a more restorative state more efficiently, improving sleep, muscle repair, and next-day performance
It also regulates neurological function, supports the production of the antioxidant glutathione, and has been associated with improved insulin sensitivity
