The family of proteins known as ephrins plays a critical role in a variety of biological processes. In a recent article in the Journal of Biological Chemistry, Hee Jun Cho, Ph.D., and colleagues report on the interaction between proteins CNK1 and ephrinB1 that promotes cell movement. Their findings may have an important implication in developing new therapeutics for reducing metastases in certain cancers.
“Eph and ephrin signaling has become an area of intense interest due to the influence these molecules exert on the control of cell adhesion and cell movement,” Cho said. “This signaling affects the formation of tissues during development and has been shown to play an instructive role in angiogenesis, as well as tumor cell invasion.”
