(Submitter supplied) Switch/sucrose nonfermentable (SWI/SNF) complexes are ATP-dependent chromatin remodeler complexes that play critical roles in timely and appropriate gene regulation by modulating chromatin architecture and DNA accessibility. SWI/SNF complexes can be grouped into three subcomplexes of differing sizes, canonical BAF (cBAF), polybromo BAF (PBAF), and newly identified noncanonical BAF (ncBAF). The most recently characterized ncBAF lacks the core BAF subunits ARID, BAF47, and BAF57, but includes unique subunits GLTSCR1/1L and BRD9, one of the bromodomain-containing proteins.We recently demonstrated the novel mechanism for the ncBAF disruption caused by mutations in a spiceosomal protein, SF3B1, especially in 65–83% for myelodysplastic syndromes (MDS) with ring sideroblasts as well as in >20% of mucosal/uveal melanomas, suggesting that the disturbed ncBAF may have some roles in the malignant hematopoiesis.Mechanistically, SF3B1 mutant recognizes an aberrant, deep intronic branchpoint within BRD9 and thereby induces the inclusion of an aberrant exon and subsequently profound degradation of BRD9 mRNA by triggering nonsense-mediated RNA decay (NMD). more...

(Submitter supplied) Chromatin remodeling caused by SWI/SNF (BAF) complexes is essential for regulating cell fates. Of these, BRD9, an essential component of the non-canonical BAF (ncBAF) complex, is post-transcriptionally decayed in multiple types of cancer, especially in myelodysplastic syndrome (MDS). However, how BRD9 loss or ncBAF disruption alters the HSCs' integrity remains unknown. Here, we identify that Brd9 loss enhances chromatin accessibility, promoting myeloid-lineage skewing at the expense of B cell development in vivo, followed by MDS development. more...

Here, we comprehensively map complex assemblies on chromatin and find that ncBAF uniquely localizes to CTCF sites and promoters. more...
