ChIP-seq peaks annotation

ChIP-seq peaks annotation 0 Hi everyone, I have a set of ChIP-seq peaks that have been annotated to my reference genome. To annotate the peaks, I have assigned a peak to a gene if the distance between the peak’s start and gene’s start is the shortest. However, in some cases,…

TRIM25 targets p300 for degradation

Introduction Protein levels are regulated at several nodes. One mode of protein level regulation acts through enhancing or reducing gene transcription. Gene transcription can be stimulated by binding transcription factors to promoters or enhancers of target genes and by posttranslational modifications of transcription factors and histones. Such modifications can be…
