Kidins220/ARMS interacts with Pdzrn3, a protein containing multiple binding domains

► Kidins220 and Pdzrn3 are coexpressed in sites where neurogenesis occurs. ► We performed biochemical assays to study their association mediated by PDZ-domain. ► Kidins220 colocalizes with HA-Pdzrn3 in PC12 cells induced with nerve growth factor.
