KSRP phosphorylated at serine193 binds 14-3-3zeta (YWHAZ) which impairs the ability of KSRP to destabilize RNA. Thus the RNAs become stabilized. KSRP is able to shuttle between the nucleus and the cytoplasm. 14-3-3zeta is nucleoplasmic. Binding of KSRP to 14-3-3zeta causes KSRP to be retained in the nucleus.
