Recombinant human Ubiquitin protein Reference: RP10122LQ Ubiquitin (Ub) is a 76 amino acid protein widely expressed in the cytoplasmic and nucleus of cells. Ub is posttranslationally conjugated to proteins by the E1, E2, E3 protein ubiquitination cascade. Ub can be conjugated on proteins as monoUb or polyUb chains. Protein ubiquitination plays both proteolytic and nonproteolytic functions. Usually, polyubiquitinated proteins are targeted to the 26S proteasome for proteolysis. Typical concentration to support in vitro ubiquitination is 50-100 μM. This product can be used for pulldwon assay to determine ubiquitin-binding proteins.
Recombinant human Ubiquitin carboxyl-terminal hydrolase 21/USP21 protein Reference: RP10129LQ USP21(195-565) contains the catalytic domain of USP21 and it is capable of cleavage of different types of polyubiquitin chains. USP21 can deubiquitinate histone H2A, a specific tag for epigenetic transcriptional repression. It can also cleave Nedd8 conjugates.
Recombinant human Ubiquitin carboxyl-terminal hydrolase... Reference: RP10130LQ USP30(57-517) contains the catalytic domain of USP30 with the N-terminal membrane bound domain being deleted. USP30 deubiquitinates substrates of Parkin including MIRO1, TOMM20, MFN1, and MFN2 on mitochondrial membranes and functions to suppress mitophagy. It prefers cleavage of K6- and K11-linked polyubiquitin chains.
Recombinant human Ubiquitin carboxyl-terminal hydrolase 4/USP4 protein Reference: RP10131LQ Usp4 is a member of the ubiquitin-specific protease family of deubiquitinating enzyme. A number of substrates of Usp4 have been identified, including TRIM21, TRAF2, TRAF6, RIG-1, RIP1, PDK1, TAK1 and etc. Usp4-mediated deubiquitination was found to regulate several signaling pathways, including the AKT signaling, RIG-1-mediated antiviral response, TNFα-induced signaling, and the Wnt signaling.
Recombinant human Sentrin-specific protease 2(catalytic domain)/SENP2 protein Reference: RP10132LQ USP9X belongs to the ubiquitin-specific protease (USP) family. USP9X has been found to deubiqitinate more than a dozen of substrates including mcl1, survivin, SMAD4, SMN and Itch. USP9X is located on the X chromosome, but it escapes X-inactivation. Mutations in this gene have been associated with Turner syndrome. Also, Usp9X is unregulated in various cancers. The catalytic domain contains the region from amino acid 1531 to amino acid 1972.
Recombinant human ZnF-UBP/USP5 protein Reference: RP10133LQ Usp5 (IsoT) is a deubiquitinase enzyme that hydrolyzes free polyubiquitin chains. The Usp5 contains two zinc finger domains (ZnF-UBP). This product contains the second ZnF-UBP domain (amino acid 163 – 291). The ZnF-UBP domains bind free ubiquitin chains’ diglycine carboxyl tail, which defines its specificity in binding of free polyubiquitin chains.

Ub is posttranslationally conjugated to proteins by the E1, E2, E3 protein ubiquitination cascade. Ub can be conjugated on proteins as monoUb or polyUb chains. Protein ubiquitination plays both proteolytic and nonproteolytic functions. Usually, polyubiquitinated proteins are targeted to the 26S proteasome for proteolysis. Typical concentration to support in vitro ubiquitination is 50-100 μM.
Recombinant human Heat shock 70 kDa protein 1A/HSP70 protein Reference: RP10135LQ HSP70 a critical chaperone protein that has a high affinity for unfolded polypeptide chains. It binds extended peptide segments with a net hydrophobic character exposed by polypeptides during translation and membrane translocation, or following stress-induced damage. In cooperation with other chaperones, Hsp70 stabilizes preexistent proteins against aggregation and mediates the folding of newly translated polypeptides in the cytosol as well as within organelles. Hsp70 and Hsp40 recruit some misfolded proteins to the ubiquitin E3 ligase CHIP for ubiquitination.
Recombinant human K11-Ub(n≥3) protein Reference: RP10138LQ Ub chains are formed by conjugating the C-terminal glycine residue of Ub onto any of seven internal lysine residues or the amino group of the previous Ub. Ub chains are classified by the lysine residue used to link Ubs; different Ub chain topologies can result in different signals. For instance, Ub chains linked through lysine 6, 11, 27, 29, 33 and 48 are capable of targeting proteins for proteasomal degradation; in contrast, Ub chains linked through lysine 63 or the N-terminal amino group (linear Ub chains) often play important nonproteolytic functions including regulation of kinase activation and protein translation. All Ub chain products are produced by using of human wild type Ub reacting with specific E2s.
Recombinant human K48-Ub(2-8) protein Reference: RP10141LQ Ub chains are formed by conjugating the C-terminal glycine residue of Ub onto any of seven internal lysine residues or the amino group of the previous Ub.
