Caspase activation and recruitment domain of RIP-associated ICH-1 homologous protein with a death domain; Caspase activation and recruitment domain (CARD) of RAIDD (RIP-associated ICH-1 homologous protein with a death domain), also known as CRADD (Caspase and RIP adaptor). RAIDD is an adaptor protein that together with the p53-inducible protein PIDD and caspase-2, forms the PIDDosome complex, which is required for caspase-2 activation and plays a role in mediating stress-induced apoptosis. RAIDD contains an N-terminal CARD, which interacts with the caspase-2 CARD, and a C-terminal Death domain (DD), which interacts with the DD of PIDD. In general, CARDs are DDs associated with caspases. They are known to be important in the signaling pathways for apoptosis, inflammation and host-defense mechanisms. 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 PYRIN and DED (Death Effector Domain). 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.

Caspase activation and recruitment domain of Caspase-2; Caspase activation and recruitment domain (CARD) similar to that found in caspase-2. Caspases are aspartate-specific cysteine proteases with functions in apoptosis and immune signaling. Caspase-2 (also known as ICH1, NEDD2, or CASP2) is one of the most evolutionarily conserved caspases, and plays a role in apoptosis, DNA damage response, cell cycle regulation, and tumor suppression. It is localized in the nucleus and exhibits properties of both an initiator and an effector caspase. In general, CARDs are death domains (DDs) found associated with caspases. They are known to be important in the signaling pathways for apoptosis, inflammation, and host-defense mechanisms. 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 PYRIN and DED (Death Effector Domain). They serve as adaptors in signaling pathways and can recruit other proteins into signaling complexes.

Fas-associated Death Domain protein-protein interaction domain; Death domain (DD) found in FAS-associated via death domain (FADD). FADD is a component of the death-inducing signaling complex (DISC) and serves as an adaptor in the signaling pathway of death receptor proteins. It modulates apoptosis as well as non-apoptotic processes such as cell cycle progression, survival, innate immune signaling, and hematopoiesis. FADD contains an N-terminal DED and a C-terminal DD. Its DD interacts with the DD of the activated death receptor, FAS, and its DED recruits the initiator caspases, caspase-8 and -10, to the DISC complex via a homotypic interaction with the N-terminal DED of the caspase. 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 they can recruit other proteins into signaling complexes.

Caspase activation and recruitment domain of CARD9 and related proteins; Caspase activation and recruitment domain (CARD) found in CARD9, CARD14 (CARMA2), CARD10 (CARMA3), CARD11 (CARMA1) and BCL10. BCL10 (B-cell lymphoma 10), together with Malt1 (mucosa-associated lymphoid tissue-lymphoma-translocation gene 1), are integral components of the CBM signalosome. They associate with CARD9 to form M-CBM (CBM complex in myeloid immune cells), and with CARD11 to form L-CBM (CBM complex in lymphoid immune cells), which mediates activation of NF-kB and MAPK by ITAM-coupled receptors expressed on immune cells. BCL10/Malt1 also associates with CARD10, which is more widely expressed and is not restricted to hematopoietic cells, to play a role in GPCR-induced NF-kB activation. CARD14 has also been shown to associate with BCL10. In general, CARDs are death domains (DDs) found associated with caspases. They are known to be important in the signaling pathways for apoptosis, inflammation, and host-defense mechanisms. 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 PYRIN and DED (Death Effector Domain).

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. They serve as adaptors in signaling pathways and can recruit other proteins into signaling complexes.
