Target Details for RAD51 Homolog B

Target: RAD51 Homolog B (Rad51B)

Alternative Name: RAD51B

Background: RAD51B antibody detects DNA repair protein RAD51 homolog 2, encoded by the RAD51B gene (also known as RAD51L1) on chromosome 14q24.1. RAD51B antibody is widely used in DNA damage response, homologous recombination, and cancer biology research. RAD51B is part of the RAD51 paralog family, which functions in homologous recombination repair of DNA double-strand breaks. It acts as a mediator, promoting the assembly and stability of RAD51 nucleoprotein filaments on single-stranded DNA.

Structurally, RAD51B is a ~42 kDa protein with ATP-binding motifs and DNA-binding domains. It forms a heterodimer with RAD51C and participates in the BCDX2 complex with RAD51C, RAD51D, and XRCC2, as well as in the CX3 complex with RAD51C and XRCC3. These complexes support RAD51 loading at DNA damage sites and stabilize recombination intermediates.

Functionally, RAD51B contributes to DNA repair fidelity by ensuring accurate homologous recombination. Loss of RAD51B impairs recombination, leading to chromosomal instability, hypersensitivity to DNA-damaging agents, and defective cell cycle checkpoints. Researchers use RAD51B antibody to study DNA repair, recombination, and genome stability.

Clinically, RAD51B variants are associated with breast cancer susceptibility and other malignancies. Disruption of RAD51B function contributes to genomic instability, a hallmark of cancer. Because homologous recombination is a therapeutic target in oncology, RAD51B is of interest in studies of PARP inhibitor sensitivity and synthetic lethality. NSJ Bioreagents provides RAD51B antibody for DNA repair and cancer research.

Experimentally, RAD51B antibody is applied in western blotting to detect the ~42 kDa protein, in immunofluorescence to study DNA repair foci, and in co-immunoprecipitation to analyze protein complexes. Chromatin immunoprecipitation with RAD51B antibody supports studies of recombination site localization.
