title: KIBRA is a novel substrate for protein kinase Czeta.
abstract: WW domain-containing proteins are found in all eukaryotic cells and they are involved in the regulation of a wide variety of cellular functions. We recently identified the neuronal protein KIBRA as novel member of this family of signal transducers. In this report, we describe the identification of protein kinase C (PKC) zeta as a KIBRA-interacting protein. PKCzeta is known to play an important role in synaptic plasticity and memory formation but its specific targets are not well known. Our studies presented here revealed that KIBRA is a novel substrate for PKCzeta and suggest that PKCzeta phosphorylation may regulate the cellular function of KIBRA.
