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.

Neuroendocrine-specific golgi protein P55 (NESP55); This family consists of several mammalian neuroendocrine-specific golgi protein P55 (NESP55) sequences. NESP55 is a novel member of the chromogranin family and is a soluble, acidic, heat-stable secretory protein that is expressed exclusively in endocrine and nervous tissues, although less widely than chromogranins.

Death domain of Ankyrin-3; Death Domain (DD) of the human protein ankyrin-3 (ANK-3) 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-3, also called anykyrin-G (for general or giant), is found in neurons and at least one splice variant has been shown to be essential for propagation of action potentials as a binding partner to neurofascin and voltage-gated sodium channels. It is required for maintaining axo-dendritic polarity, and may be a genetic risk factor associated with bipolar disorder. ANK-3 may also play roles in other cell types. Mutations affecting ANK-3 pathways for Na channel localization are associated with Brugada syndrome, a potentially fatal arrythmia. 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 p53-induced protein with a death domain; Death domain (DD) found in PIDD (p53-induced protein with a death domain) and similar proteins. PIDD is a component of the PIDDosome complex, which is an oligomeric caspase-activating complex involved in caspase-2 activation and plays a role in mediating stress-induced apoptosis. The PIDDosome complex is composed of three components, PIDD, RAIDD and caspase-2, which interact through their DDs and DD-like domains. The DD of PIDD interacts with the DD of RAIDD, which also contains a Caspase Activation and Recruitment Domain (CARD) that interacts with the caspase-2 CARD. Autoproteolysis of PIDD determines the downstream signaling event, between pro-survival NF-kB or pro-death caspase-2 activation. 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, DED (Death Effector Domain), and PYRIN.

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.

Death domain of FAS or TNF receptor superfamily member 6; Death Domain (DD) found in the FS7-associated cell surface antigen (FAS). FAS, also known as TNFRSF6 (TNF receptor superfamily member 6), APT1, CD95, FAS1, or APO-1, together with FADD (Fas-associating via Death Domain) and caspase 8, is an integral part of the death inducing signalling complex (DISC), which plays an important role in the induction of apoptosis and is activated by binding of the ligand FasL to FAS. FAS also plays a critical role in self-tolerance by eliminating cell types (autoreactive T and B cells) that contribute to autoimmunity. 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.
