Recombinant Human RAD51B-11R Protein

Product Name: Recombinant Human RAD51B-11R Protein
Catalog #:  hRP-1691
Manufacture:  LD Biopharma, Inc.

The protein encoded by human DNA repair protein RAD51 homolog 2 (RAD51B) gene is a member of the RAD51 protein family. RAD51 family members are evolutionarily conserved proteins essential for DNA repair by homologous recombination. This protein has been shown to form a stable heterodimer with the family member RAD51C, which further interacts with the other family members, such as RAD51, XRCC2, and XRCC3. RAD51B is involved in the homologous recombination repair (HRR) pathway of double-stranded DNA breaks arising during DNA replication or induced by DNA –damaging agents. Over-expression of this gene was found to cause cell cycle G1 delay and cell apoptosis, which suggested a role of this protein in sensing DNA damage. At least three alternatively spliced transcript variants encoding distinct isoforms have been observed. Rearrangements between this locus and high mobility group AT-hook 2 ( HMGA2 ) have been observed in uterine leiomyomata.

Full-length human RAD51B (383aa, Isoform-I, derived from BC030219) gene was constructed using gene synthesis technology with codon optimization. 29 aa (T7 / His / TEV cleavage site) Tag fusion at N-terminal, and 11R tag fusion at Cerminal. 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.
