A new study published online in Nature Immunology ahead of the June 2009 print issue has found that homologous immunoglobulin (lg) alleles pair up in the nucleus at stages that coincide with V(D)J recombination of the heavy and light chain (Igh and Igk) loci. Researchers led by Jane A. Skok Ph.D., assistant professor in the Department of Pathology at NYU School of Medicine and a member of the NYU Cancer Institute, showed that the V(D)J recombinase, which consists of the RAG1 and RAG2 proteins, mediates this pairing and helps ensure that only one allele undergoes recombination at a time (a process known as allelic exclusion).
