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.

| comment | FUNCTION ATP-dependent chromatin-remodeling factor which functions as substrate recognition component of the transcription regulatory histone acetylation (HAT) complex SAGA. Regulates polymerase II transcription. Also required for efficient transcription by RNA polymerase I, and more specifically the polymerase I transcription termination step. Regulates negatively DNA replication. Not only involved in transcription-related chromatin-remodeling, but also required to maintain a specific chromatin configuration across the genome. Is also associated with histone deacetylase (HDAC) activity (By similarity). Required for the bridging of SNF2, the FACT complex, the PAF complex as well as the U2 snRNP complex to H3K4me3. Functions to modulate the efficiency of pre-mRNA splicing in part through physical bridging of spliceosomal components to H3K4me3 (PubMed:18042460, PubMed:28866611). Required for maintaining open chromatin and pluripotency in embryonic stem cells (By similarity).CATALYTIC ACTIVITY ATP + H2O = ADP + phosphate + H(+)SUBUNIT Component of the SAGA complex (By similarity). Interacts with BCLAF1, NCoR, SRP20 and SAFB (By similarity). Specifically interacts with methylated H3K4me2 and H3K4me3. Interacts with the FACT complex, the PAF complex and the U2 snRNP. Interacts directly with PAF1, SFA3A1, SFA3A2, SFA3A3, SNF2 and SSRP1.INTERACTION Is released into the cytoplasm when cells enter mitosis and is reincorporated into chromatin during telophase-cytokinesis.ALTERNATIVE PRODUCTS Expressed in many tissues including in the brain, where the highest level of expression is found in the cerebellum and basal ganglia.DOMAIN The 2 chromodomains are involved in the binding to the histone H3 methyllysine at position 4 (H3K4me3).DOMAIN The CHD1 helical C-terminal domain (CHCT) binds DNA and nucleosomes.DISEASE The disease is caused by variants affecting the gene represented in this entry.SIMILARITY Belongs to the SNF2/RAD54 helicase family. |
