== Function == | |||
[[http://www.uniprot.org/uniprot/TRAF4_HUMAN TRAF4_HUMAN]] Adapter protein and signal transducer that links members of the tumor necrosis factor receptor (TNFR) family to different signaling pathways. Plays a role in the activation of NF-kappa-B and JNK, and in the regulation of cell survival and apoptosis. Regulates activation of NF-kappa-B in response to signaling through Toll-like receptors. Required for normal skeleton development, and for normal development of the respiratory tract (By similarity). Required for activation of RPS6KB1 in response to TNF signaling. Modulates TRAF6 functions.<ref>PMID:12023963</ref> <ref>PMID:12801526</ref> <ref>PMID:16052631</ref> <ref>PMID:16157600</ref> <ref>PMID:18953416</ref> <ref>PMID:19937093</ref> | |||

== Publication Abstract from PubMed == | |||
Tumor necrosis factor (TNF)-receptor associated factor 4 (TRAF4), an adaptor protein with E3-ligase activity, is involved in embryogenesis, cancer initiation and progression, and platelet receptor (GPIb-IX-V complex and GPVI)-mediated signaling for reactive oxygen species (ROS) production that initiates thrombosis at arterial shears. Disruption of platelet receptors and the TRAF4 interaction is a potential target for therapeutic intervention by antithrombotic drugs. Here, we report a crystal structure of TRAF4 (amino acid residues 290 approximately 470) in complex with a peptide from the GPIbbeta receptor (amino acid residues 177 approximately 181). The GPIbbeta peptide binds to a unique shallow surface composed of two hydrophobic pockets on TRAF4. Further studies revealed the TRAF4-binding motif Arg-Leu-X-Ala. The TRAF4-binding motif was present not only in platelet receptors but also in the TGF-beta receptor. The current structure will provide a template for furthering our understanding of the receptor-binding specificity of TRAF4, TRAF4-mediated signaling, and related diseases. | |||
