Query author contributions in Reactome

Reactome depends on collaboration between our curation team and outside experts to assemble and peer-review its pathway modules. The integration of ORCID within Reactome enables us to meet a key challenge with authoring, curating and reviewing biological information by incentivizing and crediting the external experts that contribute their expertise and time to the Reactome curation process. More information is available at ORCID and Reactome.

If you have an ORCID ID that is not listed on this page, please forward this information to us and we will update your Reactome pathway records.

commentFUNCTION Component of heterochromatin, which recognizes and binds histone H3 tails methylated at 'Lys-9', leading to epigenetic repression (PubMed:11242053). Also recognizes and binds histone H1.4 methylated at 'Lys-26' (H1.4K26me) (By similarity). Interaction with lamin B receptor (LBR) can contribute to the association of the heterochromatin with the inner nuclear membrane (PubMed:11571267).SUBUNIT Homodimer (PubMed:10747027). Interacts directly with CHAF1A, EMSY, LBR, TIF1/TIF1A and TRIM28/TIF1B PXVXL motif via the chromoshadow domain (PubMed:10562550, PubMed:10747027, PubMed:8978696). Interacts directly with histone H3 methylated at 'Lys-9' via the chromo domain (PubMed:11571267). Interacts with SUV39H1, SETDB1, KMT5B and KMT5C (PubMed:10202156, PubMed:15145825). Interacts with PRDM6 (PubMed:16537907). Interacts with POGZ (By similarity). Interacts with CHAMP1 (By similarity). Interacts with INCENP (By similarity). Interacts with SGO1; the CBX1 homodimer binds to one molecule of SGO1 (By similarity). Interacts with LRIF1 (via PxVxL motif) (By similarity). Interacts with HDGFL2 (By similarity). Interacts with CHD3 (By similarity). Interacts with CHD4 (By similarity).INTERACTION Unassociated with chromosomes during mitosis.TISSUE SPECIFICITY In all adult and embryonic tissues.PTM Not phosphorylated.PTM Ubiquitinated.
