  • The link between the LYPxL motif and ESCRT was then established by identifying the ESCRT-associated protein Alix as a binding partner of LYPxL ( Strack,2003 ). (eu.org)

  • cGAS is activated upon binding of cytosolic DNA and produces cGAMP and then activates STING (Stimulator of Interferon Genes) [4]. (gw786034inhibitor.com)
  • FLIM-FRET analysis of protein-protein interactions showed that PLIN5 S155 phosphorylation regulates PLIN5 interaction with adipose triglyceride lipase at the lipid droplet, but not with α-β hydrolase domain-containing 5. (uci.edu)
  • However, RACK1 is a multifunctional protein that both controls translation directly and acts as a scaffold for signaling to and from the ribosome. (bvsalud.org)
  • High-resolution structures of GPR56 and LPHN3 in their active, G-protein-coupled states, reveal that after dissociation of the extracellular region, the decrypted TA peptides engage the seven-transmembrane domain core with a notable conservation of interactions that also involve extracellular loop 2. (stanford.edu)
  • The innate immune ing the recently identified IPS-1/MAVS protein ( 5,6 ). (cdc.gov)
  • In addition, they provide a structural framework for innovative approaches to treat viral diseases, autoimmune disorders, and cancer by manipulating the innate immune response. (grantome.com)
  • Subsequently, MAVS proteins bind to each other through the CARD and TM domain to recruit several downstream signaling factors to form the MAVS signaling complex. (wikipedia.org)
  • The HCV NS3-NS4A strain inactivates MAVS signaling by cleaving the MAVS protein directly upstream of MAVS membrane-targeting domain in the MAM and peroxisome, preventing MAVS downstream signaling. (wikipedia.org)
  • RIG-I and MDA5 differ in the viral RNA that they recognize, but they share many structural features, including the N-terminal CARD that allows them to bind to MAVS. (wikipedia.org)
  • Ribonucleic acid (RNA) has multiple roles in cellular functions, from coding genes to non-coding regulatory activities. (biomedcentral.com)
  • To some degree, all of these accessory proteins have been structurally and/or functionally characterized. (biorxiv.org)
  • MAVS is also known as IFN-β promoter stimulator I (IPS-1), caspase activation recruitment domain adaptor inducing IFN-β(CARDIF), or virus induced signaling adaptor (VISA). (wikipedia.org)
  • MAVS is encoded by a MAVS gene. (wikipedia.org)
  • MAVS is a 540 amino acid protein that consists of three components, a N terminal caspase activation recruitment domain (CARD), a proline rich domain, and a transmembrane C terminal domain (TM). (wikipedia.org)
  • The initial translation site generates the full-length MAVS protein. (wikipedia.org)
  • The alternative translation site generates a shorter protein, termed as "miniMAVS" or short-MAVS (sMAVS). (wikipedia.org)
  • sMAVS is a 398 amino acid MAVS protein that lacks the CARD domain. (wikipedia.org)
  • This is significant because the CARD domain is where two cytosolic proteins bind to activate MAVS, signaling that there is a virus present in the cell. (wikipedia.org)
  • At a resting state for the cell, a protein called mitofusin 2 (MFN2) is known to interact with MAVS, preventing MAVS from binding to the cytosolic proteins, such as RIG-I and MDA5. (wikipedia.org)
