EPIGENETICS & CHROMATIN STATES - An introduction to histone modifications & gene transcription roles

Video Description

This lecture introduces you to histones and histone modifications and how they contribute to transcriptional regulation. It is an ideal starting point for those who are new to the subject or professionals in other fields needing a quick primer. Contents: 0:35 Defining the epigenetic memory of gene expression 2:37 Chromatin and histones 7:12 Histone modifications 7:59 Histone acetylation and reading by bromodomain proteins 12:02 Histone methylation and reading by chromodomain proteins 19:17 The complex language of histone modifications 21:53 How a core set of marks help define chromatin states This lecture is brought to you by Dr Adam West in the College of Medical Veterinary and Life Sciences at the University of Glasgow, Scotland.
