title: MARs of antigen receptor and co-receptor genes.
abstract: MARs are cis-acting DNA sequences that function both negatively and positively in conjunction with transcriptional enhancers to regulate antigen receptor and co-receptor genes. Evidence exists that certain tissue-specific nuclear proteins are involved in this regulation, including SATB1, Bright, and Cux/CDP, possibly by modulating intranuclear gene location, histone acetylation, DNA methylation, and/or nucleosome positioning.
