Abstract:Among the proteins putatively interacting with PTPRJ, a tyrosine phosphatase with tumor suppressor activity, we focused on the oncoprotein CD98hc as a very interesting candidate for the development of innovative targeted drugs. In fact, CD98hc, representing the heavy chain of a transmembrane aminoacid transporter, is overexpressed in several human cancers. Furthermore, CD98hc higher expression is associated with poor prognosis in lung cancer patients. CD98hc is linked to light chains (LATs, xCT) by disulfide b… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
