CBX1 Component of heterochromatin. Recognizes and binds histone H3 tails methylated at 'Lys-9', leading to epigenetic repression. Interaction with lamin B receptor (LBR) can contribute to the association of the heterochromatin with the inner nuclear membrane. Expressed in all adult and embryonic tissues. Note: This description may include information from UniProtKB.
