Recombinant Human USP3 Protein

Product Name: Recombinant Human USP3 Protein
Catalog #:  hTF-1785
Manufacture:  LD Biopharma, Inc.

Ubiquitin carboxyl-terminal hydrolase 3 (USP3) gene encodes a hydrolase that deubiquitinates monoubiquitinated target proteins such as histone H2A and H2B. It is required for proper progression through S phase and subsequent mitotic entry. It may also regulate the DNA damage response (DDR) checkpoint through deubiquitination of H2A at DNA damage sites. It is associates with the chromatin. Recent data indicated that USP3 plays a role in regulating ER stress pathway, which has been linked to type-I diabetes, and Parkinson’s diseases.

Full-length human USP3 cDNA (519 aa, Isoform-1, derived from BC065300) was constructed with codon optimized gene synthesis technology, and fusion with 30 aa N-terminal T7 / His / TEV cleavage site Tag. This protein was expressed in E. coli as inclusion bodies. The final product was refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified.
