Functional role of p33ING1 phosphorylation in cellular stress responses to DNA damage

The organization of DNA sequences within a structured framework is vital to maintain the stability of a cell’s genetic material. When DNA damage occurs and is left unrepaired, it can affect cell division and normal cellular functions and ultimately lead to cancer. Eric Campos is expanding previous knowledge generated in Dr. Gang Li’s lab around a tumour suppressing protein known as p33ING1. This protein has been found to play an important role in the cell’s response to ultraviolet radiation, enhancing the repair of UV-damaged DNA. Eric’s research focuses on the biochemical processes by which p33ING1 is activated. This work could lead to novel treatments for cancer, a disease caused by the onset of genomic instability.
