The serine/threonine kinase HIPK2 interacts with TRADD, but not with CD95 or TNF-R1 in 293T cells
HIPK2 has been described as a homoedomain-interacting protein kinase with a nuclear localization. Here we describe that HIPK2 can also associate with TRADD, a protein that interacts with tumor necrosis factor receptor type 1 (TNF-R1). Under the conditions where HIPK2/TRADD association was found, no direct interaction of HIPK2 with CD95, TNF-R1, FADD or caspase-8 could be detected. Therefore, HIPK2 may play a role in TNF-R1 mediated signaling.
