Abstract

Transcriptional regulation of eukaryotic protein-coding genes requires the participation of site-specific transcription factors that bind distal regulatory elements, as well as factors that, together with RNA polymerase II, form the basal transcription machinery at the core promoter. Gene regulation requires proper communication between promoters and enhancers, often over great distances. Therefore, it is important to understand the potentially inter-related transcription factor interactions at both of these elements. How this is achieved on tissue-specific genes, such as the immunoglobulin heavy chain (IgH) in B cells remains unclear. Here, we review known interactions at the Igh variable region (V(H)) promoters and present our perspective on promoter-enhancer interactions that are likely important for Ig gene regulation in B cells.
