The protein encoded by this gene shares similarity with Saccharomyces cerevisiae Rad52, a protein important for DNA double-strand break repair and homologous recombination. This gene product was shown to bind single-stranded DNA ends, and mediate the DNA-DNA interaction necessary for the annealing of complementary DNA strands. It was also found to interact with DNA recombination protein RAD51, which suggested its role in RAD51 related DNA recombination and repair. Four alternatively spliced transcript variants encoding different isoforms have been reported for this gene. The alpha variant encodes the longest isoform that contains an identical N-terminus, but a distinct C-terminus, as compared to other isoforms (beta, delta, and gamma).
This affinity purified antibody was prepared from whole rabbit serum produced by repeated immunizations with a synthetic peptide corresponding to aa 360 - 375 of the Human Rad 52 protein.
