The IBC2 chemical screening unit under the lead of Alexandra Stolz contributed to a study now published in Science. In the study, researchers from Karolinska Institutet and colleagues improved the function of a protein called OGG1, an enzyme that repairs oxidative DNA damage, implicated in ageing and diseases such as Alzheimer’s, cancer, and autoimmunity. The team examined how catalyst molecules, previously described by others, bind to OGG1 and affect its function in cells. One of the molecules proved to be of particular interest: it enabled the enzyme to cut DNA in an unusual way such that it no longer required its usual counterpart, APE1 to work, but relied on another protein called PNKP1. Potentially, OGG1 proteins improved in this way can be exploited as novel drugs for diseases in which oxidative damage is implicated.... (read more)
IBC2 director Ivan Đikić has been awarded with an Advanced Grant of the European Research Council (ERC). This is the third time he receives the prestigious grant that comes along with research funding in the amount of € 2.5 million for the next five years.
With his grant, Ivan Đikić intends to unravel molecular mechanisms of endoplasmic reticulum (ER) remodelling via ER-phagy pathways. The endoplasmic reticulum (ER) is the largest intracellular membrane system and covers important functions in numerous processes. It is essential for cellular homeostasis and wellbeing. To fulfill its diverse functions, the ER is constantly adapting its shape, and Ivan Đikić is amongst the pioneers in shedding light on the regulation of these dynamic changes. He postulated that ER-phagy, a selective autophagy route targeting ER, is a major driver of ER remodelling and found first molecular cues on how this process is regulated.
