title: Identification of a human RAD52 pseudogene located on chromosome 2.
abstract: A human testis cDNA library was screened with a hybridization probe encoding the mouse RAD52 gene. Two classes of clones were identified, one derived from the human RAD52 homolog (hRAD52), the other derived from a pseudogene. In addition to many point mutations, several of which encode stop codons, the pseudogene contains a number of frame shifts and a 103-bp deletion. We further determined that the pseudogene is processed and is located on human chromosome 2, in contrast to hRAD52 which is found on chromosome 12. Reverse transcription-PCR analysis of cultured human diploid fibroblasts, as well as fibrosarcoma cells, revealed that while hRAD52 is expressed at low, but detectable levels in these cells, the pseudogene is not.
