Death Domain Superfamily of protein-protein interaction domains; The Death Domain (DD) superfamily includes the DD, Pyrin, CARD (Caspase activation and recruitment domain) and DED (Death Effector Domain) families. 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. They serve as adaptors in signaling pathways and can recruit other proteins into signaling complexes. They are prominent components of the programmed cell death (apoptosis) pathway and are found in a number of other signaling pathways including those that impact innate immunity, inflammation, differentiation, and cancer.

canonical PDZ domain; Canonical PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain. PDZ domains usually bind to short specific peptide sequences located at the C-terminal end of their partner proteins known as PDZ binding motifs. These domains can also interact with internal peptide motifs and certain lipids, and can take part in a head-to-tail oligomerization with other PDZ domains. The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands. The canonical PDZ domain contains six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2), arranged in the order: beta-strands A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F.

Src Homology 3 domain superfamily; Src Homology 3 (SH3) domains are protein interaction domains that bind proline-rich ligands with moderate affinity and selectivity, preferentially to PxxP motifs. Thus, they are referred to as proline-recognition domains (PRDs). SH3 domains are less selective and show more diverse specificity compared to other PRDs. They have been shown to bind peptide sequences that lack the PxxP motif; examples include the PxxDY motif of Eps8 and the RKxxYxxY sequence in SKAP55. SH3 domain containing proteins play versatile and diverse roles in the cell, including the regulation of enzymes, changing the subcellular localization of signaling pathway components, and mediating the formation of multiprotein complex assemblies, among others. Many members of this superfamily are adaptor proteins that associate with a number of protein partners, facilitating complex formation and signal transduction.

Caspase activation and recruitment domain of CARD10-like proteins; Caspase activation and recruitment domain (CARD) similar to that found in CARD10, also known as CARMA3 (caspase recruitment domain-containing membrane-associated guanylate kinase protein 3) or BIMP1. The CARMA3-BCL10-MALT1 signalosome plays a role in the GPCR-induced NF-kB activation. CARMA3 is more widely expressed than CARMA1, which is found only in hematopoietic cells. In endothelial and smooth muscle cells, CARMA3-mediated NF-kB activation induces pro-inflammatory signals within the vasculature and is a key factor in atherogenesis. In bronchial epithelial cells, CARMA3-mediated NF-kB signaling is important for the development of allergic airway inflammation. 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.

CARD11 (also known as CARD-containing MAGUK protein 1, CARMA1, Bimp3) and CARD14 (also known as CARD-containing MAGUK protein 2, CARMA2, Bimp2) belong to the CARD-containing membrane-associated guanylate kinase (MAGUK) protein family. They play several crucial biological functions, including regulation of immune response and inflammation. The CARD11-Bcl10-MALT1 (CBM) complex bridges T cell receptor signaling to the canonical IkappaB kinase (IKK)/NF-kappaB pathway. CARD14 can form an analogous biochemical complex to activate NF-kappaB during specialized immunity. The CBM complex of CARD14/CARMA2 may bind with TRAF6 and get involved in IL-17 pathways in keratinocytes. The preponderance of protein interactions occurs through the N-terminal half of CARD11 that includes the CARD, LATCH, and coiled-coil domains; the C-terminal PDZ-SH3-MAGUK region binds the adhesion and degranulation-promoting adapter protein (ADAP) and aryl hydrocarbon receptor interacting protein (AIP). PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands.

Src homology 3 domain of the Tight junction proteins, Zonula occludens (ZO) proteins; ZO proteins are scaffolding proteins that associate with each other and with other proteins of the tight junction, zonula adherens, and gap junctions. They play roles in regulating cytoskeletal dynamics at these cell junctions. They are considered members of the MAGUK (membrane-associated guanylate kinase) protein family, which is characterized by the presence of a core of three domains: PDZ, SH3, and guanylate kinase (GuK). The GuK domain in MAGUK proteins is enzymatically inactive; instead, the domain mediates protein-protein interactions and associates intramolecularly with the SH3 domain. Vertebrates contain three ZO proteins (ZO-1, ZO-2, and ZO-3) with redundant and non-redundant roles. They contain three PDZ domains, followed by SH3 and GuK domains; in addition, ZO-1 and ZO-2 contains a proline-rich (PR) actin binding domain at the C-terminus while ZO-3 contains this PR domain between the second and third PDZ domains. The C-terminal regions of the three ZO proteins are unique. The SH3 domain of ZO-1 has been shown to bind ZONAB, ZAK, afadin, and Galpha12. SH3 domains are protein interaction domains that bind to proline-rich ligands with moderate affinity and selectivity, preferentially to PxxP motifs. They play versatile and diverse roles in the cell including the regulation of enzymes, changing the subcellular localization of signaling pathway components, and mediating the formation of multiprotein complex assemblies.

Src homology 3 domain of the Tight junction protein, Zonula occludens protein 1; ZO-1 is a scaffolding protein that associates with other ZO proteins and other proteins of the tight junction, zonula adherens, and gap junctions. ZO proteins play roles in regulating cytoskeletal dynamics at these cell junctions. ZO-1 plays an essential role in embryonic development. It regulates the assembly and dynamics of the cortical cytoskeleton at cell-cell junctions. It is considered a member of the MAGUK (membrane-associated guanylate kinase) protein family, which is characterized by the presence of a core of three domains: PDZ, SH3, and guanylate kinase (GuK). The GuK domain in MAGUK proteins is enzymatically inactive; instead, the domain mediates protein-protein interactions and associates intramolecularly with the SH3 domain. The C-terminal region of ZO-1 is the largest of the three ZO proteins and contains an actin-binding region and domains of unknown function designated alpha and ZU5. The SH3 domain of ZO-1 has been shown to bind ZONAB, ZAK, afadin, and Galpha12. SH3 domains are protein interaction domains that bind to proline-rich ligands with moderate affinity and selectivity, preferentially to PxxP motifs. They play versatile and diverse roles in the cell including the regulation of enzymes, changing the subcellular localization of signaling pathway components, and mediating the formation of multiprotein complex assemblies.

ZO proteins play roles in regulating cytoskeletal dynamics at these cell junctions. ZO-2 plays an essential role in embryonic development. It is critical for the blood-testis barrier integrity and male fertility. It also regulates the expression of cyclin D1 and cell proliferation. It is considered a member of the MAGUK (membrane-associated guanylate kinase) protein family, which is characterized by the presence of a core of three domains: PDZ, SH3, and guanylate kinase (GuK). The GuK domain in MAGUK proteins is enzymatically inactive; instead, the domain mediates protein-protein interactions and associates intramolecularly with the SH3 domain. The C-terminal region of ZO-2 contains an actin-binding region and a domain of unknown function designated beta. The SH3 domain of the related protein ZO-1 has been shown to bind ZONAB, ZAK, afadin, and Galpha12.

PDZ domain 3 of Zonula Occludens-1 (ZO-1), homologs ZO-2 and ZO-3, and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain 3 of ZO-1, -2, -3 and related domains. Zonula occludens proteins (ZO-1, ZO-2, ZO-3) are multi-PDZ domain proteins involved in the maintenance and biogenesis of multi-protein networks at the cytoplasmic surface of intercellular contacts in epithelial and endothelial cells. They have three N-terminal PDZ domains, PDZ1-3, followed by a Src homology-3 (SH3) domain and a guanylate kinase (GuK)-like domain. Among protein-protein interactions for all ZO proteins is the binding of the first PDZ domain (PDZ1) to the C-termini of claudins , and the homo- and hetero-dimerization of ZO-proteins via their second PDZ domain (PDZ2), which takes place by symmetrical domain swapping of the first two beta-strands of PDZ2. At the cell level, ZO-1 and ZO-2 are involved in polarity maintenance, gene transcription, cell proliferation, and tumor cell metastasis. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands. This ZO family PDZ3 domain is a canonical PDZ domain containing six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2), arranged in the order: beta-strands A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F.
