Cysteine peptidase C12 containing ubiquitin carboxyl-terminal hydrolase (UCH) families UCH37 ...
7-218 1.58e-120

Cysteine peptidase C12 containing ubiquitin carboxyl-terminal hydrolase (UCH) families UCH37 (UCH-L5) and BAP1; This ubiquitin C-terminal hydrolase (UCH) family includes UCH37 (also known as UCH-L5) and BRCA1-associated protein-1 (BAP1). They contain a UCH catalytic domain as well as an additional C-terminal extension which plays a role in protein-protein interactions. UCH37 is responsible for ubiquitin (Ub) isopeptidase activity in the 19S proteasome regulatory complex; it disassembles Lys48-linked poly-ubiquitin from the distal end of the chain. It is also associated with the human Ino80 chromatin-remodeling complex (hINO80) in the nucleus and can be activated through transient association of hINO80 with hRpn13 that is bound to the 19S regulatory particle or the proteasome. UCH37 possibly plays a role in oncogenesis; it competes with Smad ubiquitination regulatory factor 2 (Smurf2, ubiquitin ligase) in binding concurrently to Smad7 in order to deubiquitinate the activated type I transforming growth factor beta (TGF-beta) receptor, thus rescuing it from proteasomal degradation. BAP1 binds to the wild-type BRCA1 RING finger domain, localized in the nucleus. In addition to the UCH catalytic domain, BAP1 contains a UCH37-like domain (ULD), binding domains for BRCA1 and BARD1, which form a tumor suppressor heterodimeric complex, and a binding domain for HCFC1, which interacts with histone-modifying complexes during cell division. The full-length human BRCA1 is a ubiquitin ligase. However, BAP1 does not appear to function in the deubiquitination of autoubiquitinated BRCA1. BAP1 exhibits tumor suppressor activity in cancer cells, and gene mutations have been reported in a small number of breast and lung cancer samples. In metastasis of uveal melanoma, the most common primary cancer of the eye, inactivating somatic mutations have been identified in the gene encoding BAP1 on chromosome 3p21.1. These mutations include several that cause premature protein termination as well as affect its UCH domain, thus implicating loss of BAP1 and suggesting that the BAP1 pathway may be a valuable therapeutic target.

246-291 4.61e-17

Ubiquitin carboxyl-terminal hydrolases; This is the C-terminal domain found in eukaryotic UCH37 proteins (also known as Ubiquitin carboxyl-terminal hydrolase isozyme L5, UCHL5). UCH37 is a subunit of two complexes: INO80, which performs ATP-dependent sliding of nucleosomes for transcriptional regulation and DNA repair, and the 26S proteasome, which performs ATP-dependent proteolysis of polyubiquitylated proteins in the cytosol and nucleus. Recruitment to the proteasome is mediated by the C-terminal domain of RPN13 (also known as ADRM1). Recruitment to INO80 is mediated by the N-terminal domain of NFRKB. Structural and biochemical analysis reveal that RPN13 and NFRKB make similar interactions with the UCH37 C-terminal domain but have very different interactions with the catalytic UCH domain that are activating in the case of RPN13 and highly inhibitory in the case of NFRKB.

Cysteine peptidase C12 contains ubiquitin carboxyl-terminal hydrolase (UCH) families L1, L3, L5 and BAP1; The ubiquitin C-terminal hydrolase (UCH; ubiquitinyl hydrolase; ubiquitin thiolesterase) family of deubiquitinating enzymes (DUBs) consists of four members to date: UCH-L1, UCH-L3, UCH-L5 (UCH37) and BRCA1-associated protein-1 (BAP1), all containing a conserved catalytic domain with cysteine peptidase activity. UCH-L1 hydrolyzes carboxyl terminal esters and amides of ubiquitin (Ub). Dysfunction of this hydrolase activity can lead to an accumulation of alpha-synuclein, which is linked to Parkinson's disease (PD) and neurofibrillary tangles, linked to Alzheimer's disease (AD). UCH-L1, in its dimeric form, has additional enzymatic activity as a ubiquitin ligase. UCH-L3 hydrolyzes isopeptide bonds at the C-terminal glycine of either Ub or Nedd8, a ubiquitin-like protein. UCH-L3 can also interact with Lys48-linked Ub dimers to protect it from degradation while inhibiting its hydrolase activity at the same time. UCH-L1 and UCH-L3 are the most closely related of the UCH members. UCH-L5 (UCH37) is involved in the deubiquitinating activity in the 19S proteasome regulatory complex. It is also associated with the human Ino80 chromatin-remodeling complex (hINO80) in the nucleus. BAP1 binds to the wild-type BRCA1 RING finger domain, localized in the nucleus. It consists of the N-terminal UCH domain and two predicted nuclear localization signals (NLSs), only one of which is functional. The full-length human BRCA1 is a ubiquitin ligase. However, BAP1 does not appear to function in the deubiquitination of autoubiquitinated BRCA1. There is growing evidence that UCH enzymes and human malignancies are closely correlated. Studies show that UCH enzymes play a crucial role in some signaling pathways and in cell-cycle regulation.

7-218 1.77e-35

Cysteine peptidase C12 containing ubiquitin carboxyl-terminal hydrolase (UCH) families L1 and L3; This ubiquitin C-terminal hydrolase (UCH) family includes UCH-L1 and UCH-L3, the two members sharing around 53% sequence identity as well as conserved catalytic residues. Both enzymes hydrolyze carboxyl terminal esters and amides of ubiquitin (Ub). UCH-L1, in dimeric form, has additional enzymatic activity as a ubiquitin ligase. It is highly abundant in the brain, constituting up to 2% of total protein, and is expressed exclusively in neurons and testes. Abnormal expression of UCH-L1 has been shown to correlate with several forms of cancer, including several primary lung tumors, lung tumor cell lines, and colorectal cancers. Mutations in the UCH-L1 gene have been linked to susceptibility to and protection from Parkinson's disease (PD); dysfunction of the hydrolase activity can lead to an accumulation of alpha-synuclein, which is linked to Parkinson's disease (PD), while accumulation of neurofibrillary tangles is linked to Alzheimer's disease (AD). UCH-L3 hydrolyzes isopeptide bonds at the C-terminal glycine of either Ub or Nedd8, a ubiquitin-like protein. It can also interact with Lys48-linked Ub dimers to protect them from degradation while inhibiting its hydrolase activity at the same time. Unlike UCH-L1, neither dimerization nor ligase activity have been observed for UCH-L3. It has been shown that levels of Nedd8 and the apoptotic protein p53 and Bax are elevated in UCH-L3 knockout mice upon cryptorchid injury, possibly contributing to profound germ cell loss via apoptosis.

Ubiquitin carboxyl-terminal hydrolases; This is the C-terminal domain found in eukaryotic UCH37 proteins (also known as Ubiquitin carboxyl-terminal hydrolase isozyme L5, UCHL5). UCH37 is a subunit of two complexes: INO80, which performs ATP-dependent sliding of nucleosomes for transcriptional regulation and DNA repair, and the 26S proteasome, which performs ATP-dependent proteolysis of polyubiquitylated proteins in the cytosol and nucleus. Recruitment to the proteasome is mediated by the C-terminal domain of RPN13 (also known as ADRM1). Recruitment to INO80 is mediated by the N-terminal domain of NFRKB. Structural and biochemical analysis reveal that RPN13 and NFRKB make similar interactions with the UCH37 C-terminal domain but have very different interactions with the catalytic UCH domain that are activating in the case of RPN13 and highly inhibitory in the case of NFRKB.
