Heterochromatin protein 1, HP1, Non-histone chromosomal protein C1A9 antigen, CG8409
HP1 alpha is a component of heterochromatin. It recognizes and binds histone H3 tails methylated at Lys-9, leading to epigenetic repression. HP1 alpha may interact with lamin B receptor (LBR). This interaction can contribute to the association of the het
