A significant indicator of prognosis

Expression of the YB-1 protein is a powerful indicator of prognosis in cancers, yet its biological role is unclear. It is known to bind mRNA molecules in the cytoplasm and it controls transcription of RNA to DNA in the nucleus.

Does it have a role in cell stress?

Our group has shown that YB-1 also interacts with the p53 protein which is very important in controlling the way cells deal with stress.  Hence, we are now working to clarify the role of YB-1 in the context of cellular stress responses to determine whether that explains its prognostic significance.
