SpletThe nucleolus is increasingly being recognized as playing an active role in the DNA damage response due to the localization of proteins involved in DNA repair including PARP1, … SpletIn cell biology, the nucleolus is defined as a sub-organelle of the nucleus of a cell (which itself is an organelle). It is a round and typically, a small granular structured body which is composed of RNA and protein substances in the cell’s nucleus.

PARPs, PAR and NAD Metabolism and Their Inhibitors in Cancer

SpletThe nucleus. The nucleus (plural, nuclei) houses the cell’s genetic material, or DNA, and is also the site of synthesis for ribosomes, the cellular machines that assemble proteins. Inside the nucleus, chromatin (DNA wrapped around proteins, described further below) is stored in a gel-like substance called nucleoplasm. Spletp53, also known as Tumor protein P53, cellular tumor antigen p53 (UniProt name), or transformation-related protein 53 (TRP53) is a regulatory protein that is often mutated in human cancers. The p53 proteins (originally thought to be, and often spoken of as, a single protein) are crucial in vertebrates, where they prevent cancer formation. As such, p53 has … josh hardin roofing
