 3-96 7.63e-41

The PB1 domain is an essential part of p62 scaffold protein (alias sequestosome 1,SQSTM) involved in cell signaling, receptor internalization, and protein turnover. The PB1 domain is a modular domain mediating specific protein-protein interaction which play roles in many critical cell processes. A canonical PB1-PB1 interaction, which involves heterodimerization of two PB1 domains, is required for the formation of macromolecular signaling complexes ensuring specificity and fidelity during cellular signaling. The interaction between two PB1 domain depends on the type of PB1. There are three types of PB1 domains: type I which contains an OPCA motif, acidic aminoacid cluster, type II which contains a basic cluster, and type I/II which contains both an OPCA motif and a basic cluster. Interactions of PB1 domains with other protein domains have been described as noncanonical PB1-interactions. The PB1 domain module is conserved in amoebas, fungi, animals, and plants.

 391-451 3.96e-34

UBA domain-like superfamily; The ubiquitin-associated (UBA) domain-like superfamily contains alpha-helical structural homology ubiquitin-binding domains, including UBA domains and coupling of ubiquitin conjugation to endoplasmic reticulum degradation (CUE) domains which share a common three-helical bundle architecture. UBA domains are commonly occurring sequence motifs found in proteins involved in ubiquitin-mediated proteolysis. They contribute to ubiquitin (Ub) binding or ubiquitin-like (UbL) domain binding. However, some kinds of UBA domains can only bind the UbL domain, but not the Ub domain. UBA domains are normally comprised of compact three-helix bundles which contain a conserved GF/Y-loop. They can bind polyubiquitin with high affinity. They also bind monoubiquitin and other proteins. Most UBA domain-containing proteins have one UBA domain, but some harbor two or three UBA domains. CUE domain containing proteins are characterized by an FP and a di-leucine-like sequence and bind to monoubiquitin with varying affinities. Some higher eukaryotic CUE domain proteins do not bind monoubiquitin efficiently, since they carry LP, rather than FP among CUE domains. This superfamily also includes many UBA-like domains found in AMP-activated protein kinase (AMPK) related kinases, the NXF family of mRNA nuclear export factors, elongation factor Ts (EF-Ts), nascent polypeptide-associated complex subunit alpha (NACA) and similar proteins. Although many UBA-like domains may have a conserved TG but not GF/Y-loop, they still show a high level of structural and sequence similarity with three-helical ubiquitin binding domains.

Zinc finger, ZZ type. Zinc finger present in Drosophila ref(2)P, NBR1, Human sequestosome 1 and related proteins. The ZZ motif coordinates two zinc ions and most likely participates in ligand binding or molecular scaffolding. Drosophila ref(2)P appears to control the multiplication of sigma rhabdovirus. NBR1 (Next to BRCA1 gene 1 protein) interacts with fasciculation and elongation protein zeta-1 (FEZ1) and calcium and integrin binding protein (CIB), and may function in cell signalling pathways. Sequestosome 1 is a phosphotyrosine independent ligand for the Lck SH2 domain and binds noncovalently to ubiquitin via its UBA domain.

UBA domain of sequestosome-1 (SQSTM) and similar proteins; SQSTM, also called EBI3-associated protein of 60 kDa (EBIAP /p60), phosphotyrosine-independent ligand for the Lck SH2 domain of 62 kDa, or ubiquitin-binding protein p62, is a widely expressed multifunctional cytoplasmic protein that is able to noncovalently bind ubiquitin and several signaling proteins, suggesting a regulatory role connected to the ubiquitin-proteasome pathway. It functions as a scaffolding protein that regulates a diverse range of signaling pathways leading to activation of the nuclear factor kappa B (NF-kappaB) family of transcription factors. It also plays a novel role in connecting receptor signals with the endosomal signaling network required for mediating TrkA-induced differentiation. SQSTM contains a PB1 dimerization domain, a tumor necrosis factor receptor-associated factor 6 (TRAF6) binding site, and a C-terminal ubiquitin-associated (UBA) domain that mediates the recognition of polyubiquitin chains and ubiquitylated substrates.

PB1 domain; Phox and Bem1p domain, present in many eukaryotic cytoplasmic signalling proteins. The domain adopts a beta-grasp fold, similar to that found in ubiquitin and Ras-binding domains. A motif, variously termed OPR, PC and AID, represents the most conserved region of the majority of PB1 domains, and is necessary for PB1 domain function. This function is the formation of PB1 domain heterodimers, although not all PB1 domain pairs associate.

Zinc-binding domain, present in Dystrophin, CREB-binding protein; Putative zinc-binding domain present in dystrophin-like proteins, and CREB-binding protein/p300 homologues. The ZZ in dystrophin appears to bind calmodulin. A missense mutation of one of the conserved cysteines in dystrophin results in a patient with Duchenne muscular dystrophy.

Zinc finger, ZZ type. Zinc finger present in dystrophin, CBP/p300 and many other proteins. The ZZ motif coordinates one or two zinc ions and most likely participates in ligand binding or molecular scaffolding. Many proteins containing ZZ motifs have other zinc-binding motifs as well, and the majority serve as scaffolds in pathways involving acetyltransferase, protein kinase, or ubiqitin-related activity. ZZ proteins can be grouped into the following functional classes: chromatin modifying, cytoskeletal scaffolding, ubiquitin binding or conjugating, and membrane receptor or ion-channel modifying proteins.

 3-95 2.38e-11

The PB1 domain is a modular domain mediating specific protein-protein interactions which play a role in many critical cell processes, such as osteoclastogenesis, angiogenesis, early cardiovascular development, and cell polarity. A canonical PB1-PB1 interaction, which involves heterodimerization of two PB1 domain, is required for the formation of macromolecular signaling complexes ensuring specificity and fidelity during cellular signaling. The interaction between two PB1 domain depends on the type of PB1. There are three types of PB1 domains: type I which contains an OPCA motif, acidic aminoacid cluster, type II which contains a basic cluster, and type I/II which contains both an OPCA motif and a basic cluster. Interactions of PB1 domains with other protein domains have been described as a noncanonical PB1-interactions. The PB1 domain module is conserved in amoebas, fungi, animals, and plants.

PB1 domain; Phox and Bem1p domain, present in many eukaryotic cytoplasmic signalling proteins. The domain adopts a beta-grasp fold, similar to that found in ubiquitin and Ras-binding domains. A motif, variously termed OPR, PC and AID, represents the most conserved region of the majority of PB1 domains, and is necessary for PB1 domain function. This function is the formation of PB1 domain heterodimers, although not all PB1 domain pairs associate.
