Sources, identification and removal of ChIP-seq artifacts
Shumilova, Aleksandra ; Převorovský, Martin (advisor) ; Fišer, Karel (referee)
Chromatin immunoprecipitation is used to enrich DNA sequences that are associ- ated with a protein of interest, and is used to map those sequences to the genomic regions. Studying these DNA-protein binding regions provides an understanding of gene regulation and chromatin remodeling. However, some signals in fact rep- resent no binding event and are known as false positives. This thesis discusses the main sources of false-positive signals that commonly arise during ChIP-seq analysis, and offers possible solutions on how to minimize or filter them. Keywords: ChIP-seq, chromatin imunoprecipitation, quality control, data filtra- tion iii
