Description:
Transcriptional regulatory elements have been shown to be necessary but not sufficient for the developmental regulation of immunoglobulin gene rearrangement in mouse precursor B cells. In the chicken lambda light chain locus, additional elements in the V-J intervening sequence are involved in negative and positive regulation of rearrangement. Here, mutation of the mouse homolog of a chicken element, located in the V(K)-J(K) intervening sequence upstream of the J(K) cluster, was shown to significantly decrease rearrangement. This cis-acting recombination-enhancing element affects the rearrangement process without being involved in regulating transcription.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ferradini, L -- Gu, H -- De Smet, A -- Rajewsky, K -- Reynaud, C A -- Weill, J C -- New York, N.Y. -- Science. 1996 Mar 8;271(5254):1416-20.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉INSERM U373, Institut Necker, Faculte de Medecine, Universite Paris V, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8596914" target="_blank"〉PubMed〈/a〉
