Cellular inhibitor of apoptosis protein (cIAP) 1 and cIAP2 set the balance between transcription factor and apoptosis signaling downstream of tumor necrosis factor (TNF) receptor superfamily members by acting as ubiquitin E3 ligases for substrates that are part of the TNF receptor complex. To fulfill this role, cIAPs must be recruited to the receptor complex by TNF-receptor-associated factor (TRAF) 2. In this study, we reconstituted the complex between baculoviral IAP repeat (BIR) 1 of cIAP1 and the coiled-coil region of TRAF2, solved the structure of BIR1 from cIAP1, and mapped key binding residues on each molecule using mutagenesis. Biophysical analysis indicates that a single BIR1 domain binds the trimeric TRAF2 coiled-coil domain. This suggests that only one IAP molecule binds to each TRAF trimer and makes it likely that the dimeric cIAPs crosslink two TRAF trimers.

[[http://www.uniprot.org/uniprot/BIRC2_HUMAN BIRC2_HUMAN]] Multi-functional protein which regulates not only caspases and apoptosis, but also modulates inflammatory signaling and immunity, mitogenic kinase signaling, and cell proliferation, as well as cell invasion and metastasis. Acts as an E3 ubiquitin-protein ligase regulating NF-kappa-B signaling and regulates both canonical and non-canonical NF-kappa-B signaling by acting in opposite directions: acts as a positive regulator of the canonical pathway and suppresses constitutive activation of non-canonical NF-kappa-B signaling. The target proteins for its E3 ubiquitin-protein ligase activity include: RIPK1, RIPK2, RIPK3, RIPK4, CASP3, CASP7, CASP8, TRAF2, DIABLO/SMAC, MAP3K14/NIK, MAP3K5/ASK1, IKBKG/NEMO and MXD1/MAD1. Can also function as an E3 ubiquitin-protein ligase of the NEDD8 conjugation pathway, targeting effector caspases for neddylation and inactivation. Acts as an important regulator of innate immune signaling via regulation of Toll-like receptors (TLRs), Nodlike receptors (NLRs) and RIG-I like receptors (RLRs), collectively referred to as pattern recognition receptors (PRRs). Protects cells from spontaneous formation of the ripoptosome, a large multi-protein complex that has the capability to kill cancer cells in a caspase-dependent and caspase-independent manner. Suppresses ripoptosome formation by ubiquitinating RIPK1 and CASP8. Can stimulate the transcriptional activity of E2F1. Plays a role in the modulation of the cell cycle.<ref>PMID:15665297</ref> <ref>PMID:18082613</ref> <ref>PMID:21145488</ref> <ref>PMID:21653699</ref> <ref>PMID:21931591</ref>
