Your Input:
CBX5Chromobox protein homolog 5; Component of heterochromatin that recognizes and binds histone H3 tails methylated at ’Lys-9’ (H3K9me), leading to epigenetic repression.

HIST2H2BEHistone H2B type 2-E; Core component of nucleosome. Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to the cellular machineries which require DNA as a template. Histones thereby play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. DNA accessibility is regulated via a complex set of post-translational modifications of histones, also called histone code, and nucleosome remodeling (126 aa)
