DAPK3 coordinates post-translational modification of STING: in unstimulated cells DAPK3 inhibits STING K48-linked poly-ubiquitination and proteasome-mediated degradation; after cGAMP stimulation DAPK3 is required for STING K63-linked poly-ubiquitination and STING–TBK1 interaction. DAPK3 also phosphorylates the E3 ligase LMO7, which is critical for LMO7–STING interaction and STING K63-linked poly-ubiquitination. |

Human ZIPK localizes to the cytoplasm and induces membrane blebbing, while murine ZIPK localizes to the nucleus (PML bodies); this species difference is linked to absence of a conserved phosphorylation site (T299) in murine ZIPK. Human ZIPK fails to bind PAR-4, while rat ZIPK binds PAR-4 efficiently, and co-expression of PAR-4 with rat ZIPK causes nuclear-to-cytoplasm translocation and blebbing. |
