Oxidative Stress Responsive Serine Rich 1 (OSR1) is a protein that plays a critical role in the cellular response to oxidative stress. Oxidative stress occurs when there is an imbalance between the production of reactive oxygen species (ROS) and the cell's ability to detoxify them or to repair the resulting damage. ROS are chemically reactive molecules containing oxygen, such as peroxides and superoxide, which can lead to cellular damage if not regulated.OSR1 contains serine-rich regions, which are often indicative of proteins that undergo extensive post-translational modifications such as phosphorylation. Phosphorylation of serine residues can significantly alter a protein's function, typically modulating its activity, localization, or interactions with other proteins. The presence of serine-rich domains in OSR1 suggests it may be regulated in this manner, especially under conditions of oxidative stress.

The function of OSR1 is associated with its ability to sense increased levels of ROS and to participate in signaling pathways that help protect the cell. This may include activating transcription factors that induce the expression of antioxidant enzymes, which work to neutralize ROS, or enhancing the cell's capacity for repair.OSR1's exact mechanisms of action are not fully understood, but it likely interacts with other proteins involved in stress response and cellular homeostasis. It may also be involved in other biological processes independent of its role in oxidative stress response, as serine-rich proteins often have multifunctional capacities.
