Protein 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). Can interact with lamin-B receptor (LBR). This interaction can contribute to the association of the heterochromatin with the inner nuclear membrane. Involved in the formation of functional kinetochore through interaction with MIS12 complex proteins.

Protein sequence and domain

Contains 2 chromo domains.

Protein 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 (By similarity). Phosphorylated during interphase and possibly hyper-phosphorylated during mitosis. / Ubiquitinated.

Protein cellular localization

Nucleus / Chromosome / Chromosome > centromere
