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.

| text | SWI/SNF complex assembly begins by the binding of a dimer of SMARC subunits (SMARCC1 and SMARCC2, also known as BAF155 and BAF 170, respectively) to SMARCD1, 2 or 3 (also known as BAF60A, BAF60B or BAF60C, respectively) (Mashtalir et al, 2018; Mashtalir et al, 2020). SMARCC has been shown to form dimers in all possible combinations, with SMARCC1 homodimers common in human embryonic stem cells (ESCs) and SMARCC1:SMARCC2 heterodimers occurring in differentiated cell types (Ho et al, 2009; Wang et al, 1996). The SMARCC:SMARCD trimer was identified as the initiating core of SWI/SNF assembly on the basis of density sedimentation and cross-linking analysis of HEK293 nuclear extracts (Mashtalir et al, 2018; Mashtalir et al 2020), in contrast to earlier studies that suggested that complex assembly nucleates around a tetramer of SMARCC1, SMARCC2, SMARCA4 and SMARCB1 (Phelan et al, 1999). |
