HP1b recombinant protein
CBX1, MOD1, M31, P25b
HP1 beta (UniProt/Swiss-Prot entry P83916) is a component of heterochromatin. It recognizes and binds to histone H3 tails methylated at 'Lys-9', leading to epigenetic repression of transcription. HP1b does not associate with chromosomes during mitosis. It may also interact with lamin B receptor (LBR), thereby contributing to the association of the heterochromatin with the inner nuclear membrane.
