Protein kinase C‐δ interacts with and phosphorylates ARD1

Protein kinase C‐δ (PKCδ) is a diacylglycerol‐dependent, calcium‐independent novel PKC isoform that is engaged in various cell signaling pathways, such as cell proliferation, apoptosis, inflammation, and oxidative stress. In this study, we searched for proteins that bind PKCδ using a yeast two‐hybrid assay and identified murine arrest‐defective 1 (mARD1) as a binding partner. The interaction between PKCδ and mARD1 was confirmed by glutathione S...
