'''Crystal Structure of a vFLIP-IKKgamma complex: Insights into viral activation of the IKK signalosome'''
===Crystal Structure of a vFLIP-IKKgamma complex: Insights into viral activation of the IKK signalosome===




==Overview==
<!--  
Key to the pathogenicity of several viruses is activation of the canonical nuclear factor-kappaB (NF-kappaB) transcriptional pathway. Subversion of this tightly regulated mechanism is achieved through the production of host mimetic viral proteins that deregulate the transcription process. One such protein is ks-vFLIP (produced by the Kaposi's sarcoma herpes virus [KSHV]), which associates with IKKgamma, an essential component of the IKK complex or signalosome. This interaction renders the canonical NF-kappaB pathway constitutively active and has been linked to Kaposi's sarcoma and other malignancies. In order to elucidate the molecular basis underpinning ks-vFLIP-induced activation of the IKK signalosome, we have determined the crystal structure of a complex involving a fragment of IKKgamma bound to ks-vFLIP at 3.2 A. In addition to identifying and subsequently probing the ks-vFLIP-IKKgamma interface, we have also investigated the effects of a mutation implicated in the genetic disorder anhydrotic ectodermal dysplasia with immunodeficiency (EDA-ID).
