Background The mechanism by which protein complexes interact to regulate the deposition of post-translational modifications of histones remains poorly understood. This is particularly important at regulatory regions, such as CpG islands (CGIs), which are known to recruit Trithorax (TrxG) and Polycomb group proteins. The CxxC zinc finger protein 1 (CFP1, also known as CGBP) is a subunit of the TrxG...
Eight percent of the human genome is derived from endogenous retrovirus (ERV) insertions. ERV long terminal repeats (LTRs) contain strong promoters that are known to contribute to the transcriptional regulation of certain human genes. While some LTRs are known to possess bidirectional promoter activity in vitro, only sense orientation LTR promoters have previously been shown to regulate human gene...
Throughout the course of vertebrate evolution, germline retroviral infections have resulted in heritable provirus insertions into host DNA. These endogenous retroviruses (ERVs) contain long terminal repeat (LTR) promoters that can be adopted for use by nearby host genes. It is not known whether the transcription factor (TF) binding sites and tissue-specificities of modern LTR gene promoters have been...
Nearly half of mammalian genomes are derived from ancient transposable elements (TEs). We analyzed the prevalence of TEs in untranslated regions of human and mouse mRNAs and found evidence suggesting that TEs affect the expression of many genes through the donation of transcriptional regulatory signals. Furthermore, we found that recently expanded gene classes, such as those involved in immunity or...
