Peak identification from ChIP-nexus data.

Proteins play a very important role in live organisms. Their roles are for example structural, transport, regulatory or catalytic. What genes will be expressed, what proteins will be made and at what rate can have a strong impact on the function or even health of the organism. Gene expression is significantly regulated by transcription factors, whose activity may cause multiple diseases or disorders (Latchman 1997). Studying those factors and their function is therefore very important. Several methods were developed to this cause, ChIP-chip, ChIP-seq, ChIP-exo and ChIP-nexus. They enable us to study the binding sites of transcription factors and other DNA-binding proteins with various degrees of resolution. In this thesis I am going to describe the above mentioned methods and peak callers, softwares used for analysis of data obtained by those methods. I will also attempt to do peak calling of ChIP-nexus data of Cbf11 protein and compare the outcomes.
