Description:
Run-on transcription experiments were used to demonstrate that transcription of T cell receptor beta chain V genes is activated by DNA rearrangement, in a manner similar to immunoglobulin genes. A transcriptional enhancer likely to be involved in this activation has been identified. A 25-kilobase region from J beta 1 to V beta 14 was tested for enhancer activity by transient transfections, and an enhancer was found 7.5 kilobases 3' of C beta 2. The beta enhancer has low activity relative to the simian virus 40 viral enhancer, does not display a preference for V beta promoters, has a T cell-specific activity, and binds two purified immunoglobulin heavy chain enhancer factors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McDougall, S -- Peterson, C L -- Calame, K -- GM29361/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1988 Jul 8;241(4862):205-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Chemistry, UCLA School of Medicine 90024.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2968651" target="_blank"〉PubMed〈/a〉
