UBE2K, Human

(HIP2, Huntingtin Interacting protein 2, HYPG, Ubiquitin-conjugating enzyme E2-25K kDa, Ubiquitin-protein ligase, Ubiquitin carrier protein, LIG, HIP-2, E2(25K), DKFZp686J24237, OTTHUMP00000218440, EC 6.3.2.19.)

UBE2K belongs to the ubiquitin-conjugating enzymes family which take part in many cellular processes such as selective protein degradation, DNA repair, cell cycle control, and sporulation. In this mechanism, the ATP-coupled activation and subsequent ligation of ubiquitin are catalyzed by separate enzymes functionally linked by ubiquitin carrier protein UBC1. In addition, UBE2K is involved in Alzheimer's disease, Huntington's disease and antigen processing through its interaction with amyloid-?, huntingtin, and MHC-heavy chain proteins.

UBE2K produced in E.Coli is a single, non-glycosylated polypeptide chain containing 236 amino acids (1-200a.a.) and having a molecular mass of 26.5kDa. UBE2K is fused to a 36 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.

Purity: Greater than 95.0% as determined by(a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.

Source: Escherichia Coli.

Physical Appearance: Sterile Filtered clear solution.

Formulation: The UBE2K protein solution (1mg/1ml) is formulated in 20mM Tris-HCl buffer (pH7.5) 1mM DTT, 50mM NaCl, and 10% glycerol.
