Summary

Description
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 (By similarity).

Subunit
Interacts directly with ATRX, CHAF1A, LBR, NIPBL, SP100 and STAM2 via the chromoshadow domain. Can interact directly with CBX3 via the chromoshadow domain. Interacts with histone H3 methylated at 'Lys-9'. Interacts with BAHD1, SETDB1, MIS12 and DSN1. Interacts with POGZ; POGZ and PXVXL motif-containing proteins such as INCENP and TRIM28 compete for interaction with CBX5. Interacts with INCENP. Interacts with CHAMP1 (By similarity). Interacts directly with TRIM28 via the chromoshadow domain (PubMed:8978696). Interacts with KMT5B and KMT5C (PubMed:15145825). Interacts with HP1BP3 and TRIM24 (PubMed:8978696). May form homodimers (PubMed:8978696). Interacts with PRR14 (via N-terminus) (By similarity). Interacts with RRP1B (By similarity). Interacts with HNRNPU (via C-terminus); this interaction is, at least in part, RNA-dependent (By similarity). Interacts with LRIF1 (via PxVxL motif) (By similarity).
Interacts with KMT5B and KMT5C (By similarity). Interacts with HP1BP3 (PubMed:20042602).

Interacts with BAHD1, MIS12 and DSN1 (PubMed:15502821, PubMed:19666599). Interacts with POGZ; POGZ and PXVXL motif-containing proteins such as INCENP and TRIM28 compete for interaction with CBX5 (PubMed:20562864, PubMed:20850016, PubMed:21346195).

(Microbial infection) Interacts with JC virus agnoprotein; this interaction induces the dissociation of CBX5 from LBR, resulting in destabilization of the nuclear envelope.
