Abstract

A CD9-binding peptide (RSHRLRLH), screened from EWI-2, was characterized, and its effect on cellular migration and invasion was evaluated. As CD9 protein is overexpressed in Cancer cells and plays an important role in cellular migration, the CD9-binding peptide preferentially inhibited the migration of Cancer cells. Unlike conventional antiproliferative drugs, this CD9-binding peptide is promising as a novel precision antimigratory agent for Cancer therapeutics.
