Termination of NF-κB activity through a gammaherpesvirus protein that assembles an EC5S ubiquitin-ligase
Host colonisation by lymphotropic gammaherpesviruses depends critically on the expansion of viral genomes in germinal centre (GC) B cells. Yet, host and virus molecular mechanisms involved in driving such proliferation remain largely unknown. Here, we show that the ORF73 protein encoded by the murid herpesvirus-4 (MuHV-4) inhibits host nuclear factor-kappa B (NF-kappaB) transcriptional activity...
متن کاملThe PAAD/PYRIN-Family Protein ASC Is a Dual Regulator of a Conserved Step in Nuclear Factor κB Activation Pathways
Apoptosis-associated speck-like protein containing a Caspase recruitment domain (ASC) belongs to a large family of proteins that contain a Pyrin, AIM, ASC, and death domain-like (PAAD) domain (also known as PYRIN, DAPIN, Pyk). Recent data have suggested that ASC functions as an adaptor protein linking various PAAD-family proteins to pathways involved in nuclear factor (NF)-kappaB and pro-Caspas...
متن کاملNix Protein Positively Regulates NF-κB Activation in Gliomas
Previous reports indicate that the NIX/BNIP3L gene acts as a pro-apoptotic factor by interacting with BCL2 and BCL-XL, playing an important role in hypoxia-dependent cell death and acting as a tumor suppressor. However, many studies also showed that NIX is linked to a protective role and cell survival in cancer cells. Nuclear factor-κB (NF-κB) can attenuate apoptosis in human cancers in respons...
متن کاملCo-Regulation of NF-κB and Inflammasome-Mediated Inflammatory Responses by Myxoma Virus Pyrin Domain-Containing Protein M013
NF-kappaB and inflammasomes both play central roles in orchestrating anti-pathogen responses by rapidly inducing a variety of early-response cytokines and chemokines following infection. Myxoma virus (MYXV), a pathogenic poxvirus of rabbits, encodes a member of the cellular pyrin domain (PYD) superfamily, called M013. The viral M013 protein was previously shown to bind host ASC-1 protein and in...
متن کاملProtein kinase C-associated kinase regulates NF-κB activation through inducing IKK activation.
Activation of the transcription factor NF-κB induced by extracellular stimuli requires IKKα and IKKβ kinase activity. How IKKα and IKKβ are activated by various upstream signaling molecules is not fully understood. We previously showed that protein kinase C-associated kinase (PKK, also known as DIK/RIP4), which belongs to the receptor-interacting protein (RIP) kinase family, mediates the B cell...
