 def: "A chromatin adaptor activity that brings together a protein and a specific form of histone, either modified by a post-translational modification, or the unmodified form. Histone readers have roles in many processes, including in centromere function or in modulating the accessibility of cis-regulatory regions to the transcription machinery."
