Web22 de fev. de 2024 · Methods such as chromatin interaction analysis (ChIA)-paired-end tag (PET), HiChIP, and PLAC-seq employ protein-centric strategies to pull down chromatin sequences that are associated with specific proteins or histone modifications ( Davies et al., 2016 ; Fang et al., 2016 ; Fullwood et al., 2009 ; Mumbach et al., 2016 WebChINN is able to predict CTCF-, RNA polymerase II- and HiC- associated chromatin interactions between open chromatin regions. ChINN was able to identify convergent CTCF motifs, AP-1 transcription family member motifs such as FOS, and other transcription factors such as MYC as being important in predicting chromatin interactions.
