Death domain of Myeloid Differentation primary response protein MyD88; Death Domain (DD) of Myeloid Differentiation primary response protein 88 (MyD88). MyD88 is an adaptor protein involved in interleukin-1 receptor (IL-1R)- and Toll-like receptor (TLR)-induced activation of nuclear factor-kappaB (NF-kB) and mitogen activated protein kinase pathways that lead to the induction of proinflammatory cytokines. It is a key component in the signaling pathway of pathogen recognition in the innate immune system. MyD88 contains an N-terminal DD and a C-terminal Toll/IL-1 Receptor (TIR) homology domain that mediates interaction with TLRs and IL-1R. In general, DDs are protein-protein interaction domains found in a variety of domain architectures. Their common feature is that they form homodimers by self-association or heterodimers by associating with other members of the DD superfamily including CARD (Caspase activation and recruitment domain), DED (Death Effector Domain), and PYRIN. They serve as adaptors in signaling pathways and can recruit other proteins into signaling complexes.

Death Domain: a protein-protein interaction domain; Death Domains (DDs) are protein-protein interaction domains found in a variety of domain architectures. Their common feature is that they form homodimers by self-association or heterodimers by associating with other members of the DD superfamily including CARD (Caspase activation and recruitment domain), DED (Death Effector Domain), and PYRIN. Structural analysis of DD-DD complexes show that the domains interact with each other in many different ways. DD-containing proteins serve as adaptors in signaling pathways and they can recruit other proteins into signaling complexes. In mammals, they are prominent components of the programmed cell death (apoptosis) pathway and are found in a number of other signaling pathways. In invertebrates, they are involved in transcriptional regulation of zygotic patterning genes in insect embryogenesis, and are components of the ToII/NF-kappaB pathway, a conserved innate immune pathway in animal cells.

Death domain of Nuclear Matrix Protein P84; Death domain (DD) found in the Nuclear Matrix Protein P84 (also known as HPR1 or THOC1). HPR1/p84 resides in the nuclear matrix and is part of the THO complex, also called TREX (transcription/export) complex, which functions in mRNP biogenesis at the interface between transcription and export of mRNA from the nucleus. Mice lacking THOC1 have abnormal testis development and are sterile. In general, DDs are protein-protein interaction domains found in a variety of domain architectures. Their common feature is that they form homodimers by self-association or heterodimers by associating with other members of the DD superfamily including CARD (Caspase activation and recruitment domain), DED (Death Effector Domain), and PYRIN.

Death domain of Interleukin-1 Receptor-Associated Kinases; Death Domains (DDs) found in Interleukin-1 (IL-1) Receptor-Associated Kinases (IRAK1-4) and similar proteins. IRAKs are essential components of innate immunity and inflammation in mammals and other vertebrates. All four types are involved in signal transduction involving IL-1 and IL-18 receptors, Toll-like receptors, nuclear factor-kappaB, and mitogen-activated protein kinase pathways. IRAK1 and IRAK4 are active kinases while IRAK2 and IRAK-M (also called IRAK3) are inactive. In general, IRAKs are expressed ubiquitously, except for IRAK-M which is detected only in macrophages. The insect homologs, Pelle and Tube, are important components of the Toll pathway, which functions in establishing dorsoventral polarity in embryos and also in the innate immune response. Most members have an N-terminal DD followed by a kinase domain. In general, DDs are protein-protein interaction domains found in a variety of domain architectures. Their common feature is that they form homodimers by self-association or heterodimers by associating with other members of the DD superfamily including CARD (Caspase activation and recruitment domain), DED (Death Effector Domain), and PYRIN. They serve as adaptors in signaling pathways and can recruit other proteins into signaling complexes.

Death domain of Ankyrin-2; Death Domain (DD) of Ankyrin-2 (ANK-2) and related proteins. Ankyrins are modular proteins comprising three conserved domains, an N-terminal membrane-binding domain containing ANK repeats, a spectrin-binding domain and a C-terminal DD. ANK-2, also called ankyrin-B (for broadly expressed), is required for proper function of the Na/Ca ion exchanger-1 in cardiomyocytes, and is thought to function in linking integral membrane proteins to the underlying cytoskeleton. Human ANK-2 is associated with "Ankyrin-B syndrome", an atypical arrythmia disorder with risk of sudden cardiac death. It also plays key roles in the brain and striated muscle. Loss of ANK-2 is associated with significant nervous system defects and sarcomere disorganization. In general, DDs are protein-protein interaction domains found in a variety of domain architectures. Their common feature is that they form homodimers by self-association or heterodimers by associating with other members of the DD superfamily including CARD (Caspase activation and recruitment domain), DED (Death Effector Domain), and PYRIN. They serve as adaptors in signaling pathways and can recruit other proteins into signaling complexes.

Death Domain of Receptor-Interacting Protein 1; Death domain (DD) found in Receptor-Interacting Protein 1 (RIP1) and related proteins. RIP kinases serve as essential sensors of cellular stress. Vertebrates contain several types containing a homologous N-terminal kinase domain and varying C-terminal domains. RIP1 harbors a C-terminal DD, which binds death receptors (DRs) including TNF receptor 1, Fas, TNF-related apoptosis-inducing ligand receptor 1 (TRAILR1), and TRAILR2. It also interacts with other DD-containing adaptor proteins such as TRADD and FADD. RIP1 plays a crucial role in determining a cell's fate, between survival or death, following exposure to stress signals. It is important in the signaling of NF-kappaB and MAPKs, and it links DR-associated signaling to reactive oxygen species (ROS) production. Abnormal RIP1 function may result in ROS accumulation affecting inflammatory responses, innate immunity, stress responses, and cell survival. In general, DDs are protein-protein interaction domains found in a variety of domain architectures. Their common feature is that they form homodimers by self-association or heterodimers by associating with other members of the DD superfamily including CARD (Caspase activation and recruitment domain), DED (Death Effector Domain), and PYRIN. They serve as adaptors in signaling pathways and can recruit other proteins into signaling complexes.
