 4-75 6.70e-34

ubiquitin-like (Ubl) domain found in Sacsin and similar proteins; Sacsin, also termed DnaJ homolog subfamily C member 29 (DNAJC29), is encoded by SACS gene that is highly expressed in the brain. Mutations in SACS can cause the neurodegenerative disease autosomal recessive spastic ataxia of Charlevoix Saguenay (ARSACS) which is characterized by early-onset spastic ataxia. Sacsin is a modular protein that is localized on the mitochondrial surface and possibaly required for normal mitochondrial network organization. Sacsin knockdown resulted in a reduction in cells expressing plyglutamine-expanded ataxin-1, which correlated with a loss of cells with large nuclear ataxin-1 incusions. At the N-terminus, sacsin contains a ubiquitin-like (Ubl) domain with a beta-grasp Ubl fold, which can interact with the proteasome. At the C-terminus, sacsin harbors a protein-protein interaction J-domain followed by an higher eukaryotes and prokaryotes nucleotide-binding (HEPN) domain. The J-domain is typically associated with DnaJ-like co-chaperones involved in regulation of the Hsp70 heat shock system.

 4279-4314 1.05e-03

DnaJ domain or J-domain. DnaJ/Hsp40 (heat shock protein 40) proteins are highly conserved and play crucial roles in protein translation, folding, unfolding, translocation, and degradation. They act primarily by stimulating the ATPase activity of Hsp70s, an important chaperonine family. Hsp40 proteins are characterized by the presence of a J domain, which mediates the interaction with Hsp70. They may contain other domains as well, and the architectures provide a means of classification.

Ubiquitin family; This family contains a number of ubiquitin-like proteins: SUMO (smt3 homolog), Nedd8, Elongin B, Rub1, and Parkin. A number of them are thought to carry a distinctive five-residue motif termed the proteasome-interacting motif (PIM), which may have a biologically significant role in protein delivery to proteasomes and recruitment of proteasomes to transcription sites.

 8-73 9.42e-08

ubiquitin-like (Ubl) domain found in ubiquitin and ubiquitin-like Ubl proteins; Ubiquitin-like (Ubl) proteins have a similar ubiquitin (Ub) beta-grasp fold and attach to other proteins in a Ubl manner but with biochemically distinct roles. Ub and Ubl proteins conjugate and deconjugate via ligases and peptidases to covalently modify target polypeptides. Some Ubl domains have adaptor roles in Ub-signaling by mediating protein-protein interaction. Prokaryotic sulfur carrier proteins are Ub-related proteins that can be activated in an ATP-dependent manner. Polyubiquitination signals for a diverse set of cellular events via different isopeptide linkages formed between the C terminus of one ubiquitin (Ub) and the epsilon-amine of K6, K11, K27, K29, K33, K48, or K63 of a second Ub. One of these seven lysine residues (K27, Ub numbering) is conserved in this Ubl_ubiquitin_like family. K27-linked Ub chains are versatile and can be recognized by several downstream receptor proteins. K27 has roles beyond chain linkage, such as in Ubl NEDD8 (which contains many of the same lysines (K6, K11, K27, K33, K48) as Ub) where K27 has a role (other than conjugation) in the mechanism of protein neddylation.

Ubiquitin family; This family contains a number of ubiquitin-like proteins: SUMO (smt3 homolog), Nedd8, Elongin B, Rub1, and Parkin. A number of them are thought to carry a distinctive five-residue motif termed the proteasome-interacting motif (PIM), which may have a biologically significant role in protein delivery to proteasomes and recruitment of proteasomes to transcription sites.

ubiquitin-like (Ubl) domain found in ubiquitin-like protein FUBI and similar proteins; FUBI is a pro-apoptotic regulatory gene FAU encoding ubiquitin-like protein with ribosomal protein S30 as a C-terminal extension. FUBI functions as a tumor suppressor protein that may be involved in the ATP-dependent proteolytic activity of ubiquitin. The N-terminal ubiquitin-like (Ubl) domain of FUBI has the beta-grasp Ubl fold, and it may act as a substitute or an inhibitor of ubiquitin or one of ubiquitin's close relatives UCRP, FAT10, and Nedd8.

ubiquitin-like (Ubl) domain found in Arabidopsis thaliana ubiquitin-protein ligase 5 (AtUPL5) and similar proteins; Arabidopsis thaliana AtUPL5, also termed HECT-type E3 ubiquitin transferase UPL5, is an E3 ubiquitin-protein ligase that contains a ubiquitin-like domain (Ubl), a C-type lectin-binding domain, a leucine zipper and a HECT domain. HECT domain containing-ubiquitin-protein ligases have more than one member in different genomes, these proteins have been classified into four sub-families (UPL1/2, UPL3/4, UPL5 and UPL6/7). AtUPL5 fUPL5 regulates leaf senescence in Arabidopsis through degradation of the transcription factor WRKY53.

 24-71 5.28e-03

ubiquitin-like (Ubl) domain found in parkin and similar proteins; Parkin, also termed Parkinson juvenile disease protein 2, is a RBR-type E3 ubiquitin-protein ligase that is associated with recessive early onset Parkinson's disease (PD), and exerts a protective effect against dopamine-induced alpha-synuclein-dependent cell toxicity. Mutations in the parkin gene cause autosomal recessive juvenile parkinsonism. Parkin functions within a multiprotein E3 ubiquitin ligase complex, catalyzing the covalent attachment of ubiquitin moieties onto substrate proteins, such as BCL2, SYT11, CCNE1, GPR37, RHOT1/MIRO1, MFN1, MFN2, STUB1, SNCAIP, SEPT5, TOMM20, USP30, ZNF746 and AIMP2. It mediates monoubiquitination as well as Lys-6-, Lys-11-, Lys-48- and Lys-63-linked polyubiquitination of substrates depending on the context. Parkin may enhance cell viability and protects dopaminergic neurons from oxidative stress-mediated death by regulating mitochondrial function. It also limits the production of reactive oxygen species (ROS), and regulates cyclin-E during neuronal apoptosis. Moreover, parkin displays a ubiquitin ligase-independent function in transcriptional repression of p53. Parkin contains an N-terminal ubiquitin-like (Ubl) domain and a C-terminal RBR domain that was previously known as RING-BetweenRING-RING domain or TRIAD [two RING fingers and a DRIL (double RING finger linked)] domain. Based on current understanding of the structural biology of RBR ligases, the nomenclature of RBR has been corrected as RING-BRcat (benign-catalytic)-Rcat (required-for-catalysis) recently. The RBR (RING1-BRcat-Rcat) domain use an auto-inhibitory mechanism to modulate ubiquitination activity, as well as a hybrid mechanism that combines aspects from both RING and HECT E3 ligase function to facilitate the ubiquitination reaction.

ubiquitin-like (Ubl) domain found in ubiquitin domain-containing proteins UBTD1, UBTD2, and similar proteins; This family represents a group of ubiquitin-like (Ubl) domain-containing proteins evolutionarily conserved and found in metazoa, fungi, and plants. They may regulate the activity and/or specificity of E2 ubiquitin conjugating enzymes belonging to the UBE2D family. Members in this family contain an N-terminal ubiquitin binding domain (UBD) and a C-terminal Ubl domain with a beta-grasp Ubl fold, a common structure involved in protein-protein interactions.
