Abstract: | The TRAIP interacting protein is known as a negative regulator of TNF-induced-nuclear factor, kappa-light-chain-enhancer of activated B cell (NF-κB) by direct interaction with the adaptor protein TRAF2, which inhibits the function of TRAF2 via the RINGCC domain protein. The TRAIP protein is composed of 469 amino acids with an N-terminal RING motif that is followed by a coiled coil (CC) and leucine zipper domain. TRAIP proteins are critical in programmed cell death, cell proliferation and differentiation, and embryonic development. The critical functions of TRAIP together with the molecular inhibitory mechanism effect of TRAIP have been reported by two different studies and have opened up new research into the field of TRAF biology. In this study, we designed different constructs of the Leucine zipper domain to find the over –expressed construct for further studies. We successfully cloned the C-terminal TRAIP containing the leucine zipper domain. In addition, we have over-expressed and purified the TRAIP LZ for their biochemical characterization. |
