| Post Translational Modifications | Phosphorylation of HP1 and LBR may be responsible for some of the alterations in chromatin organization and nuclear structure which occur at various times during the cell cycle. Phosphorylated during interphase and possibly hyper-phosphorylated during mitosis. Ubiquitinated. |
| Function | Component of heterochromatin that recognizes and binds histone H3 tails methylated at 'Lys-9' (H3K9me), leading to epigenetic repression. In contrast, it is excluded from chromatin when 'Tyr-41' of histone H3 is phosphorylated (H3Y41ph). May contribute to the association of heterochromatin with the inner nuclear membrane by interactions with the lamin-B receptor (LBR). Involved in the formation of kinetochore through interaction with the MIS12 complex subunit NSL1. Required for the formation of the inner centromere. |
