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. |Chromo shadow| |Chromo| |histone methyltransferase binding| |male pronucleus| |female pronucleus| |chromocenter| |pericentric heterochromatin| |site of DNA damage| |nuclear heterochromatin| |chromosome, centromeric region| |nuclear chromosome, telomeric region| |chromatin| |spindle| |enzyme binding| |chromatin binding| |cellular response to DNA damage stimulus| |protein homodimerization activity| |negative regulation of transcription, DNA-templated| |negative regulation of nucleic acid-templated transcription| |negative regulation of RNA biosynthetic process| |negative regulation of RNA metabolic process| |negative regulation of cellular macromolecule biosynthetic process| |negative regulation of nucleobase-containing compound metabolic process| |negative regulation of macromolecule biosynthetic process| |negative regulation of cellular biosynthetic process| |negative regulation of biosynthetic process| |cellular response to stress| |negative regulation of gene expression| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp242|Radicicol 0.16μM R05 exp242]]|1.71| |[[:results:exp216|Erlotinib 10μM R05 exp216]]|1.72| No correlation found to any other genes in chemogenomics.
