Nucleosome dynamics
WebMany structural studies have shed light on how these proteins are recruited to the nucleosome, and how they affect nucleosome structure and dynamics. Nucleosomes provides many unique structural features for protein recruitment, and indeed, these factors target either nucleosomal or extra-nucleosomal DNA, the histone core surface, histone … WebTo determine whether global nucleosome and citrullinated nucleosome levels were elevated in COVID-19 patients, ... However, intrinsic or acquired unresponsiveness to immunotherapies does occur due to the dynamic cancer immunoediting which ultimately leads to immune escape.
