DESCRIPTION CATALOG # SIZE PRICE
Recombinant Human Ubiquitin Conjugating Enzyme 12 (His6-tagged) CRP08138 1mg Please Inquiry
Product Detail
Cat
CRP08138
Product Overview
Recombinant Human Ubiquitin Conjugating Enzyme 12 produced in E.coli is a single non-glycosylated polypeptide chain containing 216 amino acids and having a molecular mass of approximately 25 kDa.
Endotoxin
Less than 1EU/μg of rHuUbcH12 as determined by LAL method.
Storage
This lyophilized preparation is stable at 2-8°C, but should be kept at -20°C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8°C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20°C to -70°C. Avoid repeated freeze/thaw cycles.
Reconstitution
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at <-20°C. Further dilutions should be made in appropriate buffered solutions.

Background
Antigen Description
UbcH12 is functional in in vitro NEDDylation reactions. It has been shown to form a thioester linkage with NEDD8 in the presence of the NEDD8 activating enzyme complex Uba3/APP-BP1. APP-BP1 binds to the amyloid precursor protein (APP) carboxy terminal domain and is important in conjunction with Uba3 and UbcH12 in driving cells through the S to M checkpoint. It was demonstrated to be the E2 responsible for the NEDDylation of the Cul-1 component of the SCF(β-TRCP) complex which is important as the E3-ligase in the ubiquitinylation of IκBα. NEDDylation of Cul-1 is essential for conjugation and processing of NF-κB p105 by SCF(β-TRCP) following phosphorylation of the complex. A dominant negative form of UbcH12, previously demonstrated to sequester NEDD8 and inhibit its conjugation, inhibits both conjugation and processing of p105, which is alleviated by wild-type UbcH12.
