| abstractText | Mammalian SWI/SNF or BAF chromatin-remodeling complexes are polymorphic assemblies of homologous subunit families that remodel nucleosomes. BAF57 is a subunit of the BAF complexes; it is encoded only in higher eukaryotes and is present in all mammalian assemblies. Its main structural feature is a high-mobility group domain, the DNA-binding properties of which suggest that BAF57 may play topological roles as the BAF complex enters or exits the nucleosome. BAF57 displays specific interactions with a number of proteins outside the BAF complex. Through these interactions, it can accomplish specific functions. In the embryo, BAF57 is responsible for the silencing of the CD4 gene during T-cell differentiation, and during the repression of neuronal genes in non-neuronal cells, BAF57 interacts with the transcriptional corepressor, Co-REST, and facilitates repression. Extensive work has demonstrated a specific role of BAF57 in regulating the interactions between BAF and nuclear hormone receptors. Despite its involvement in oncogenic pathways, new generation sequencing studies do not support a prominent role for BAF57 in the initiation of cancer. On the other hand, evidence has emerged to support a role for BAF57 as a metastasis factor, a prognosis marker and a therapeutic target. In humans, BAF57 is associated with disease, as mutations in this gene predispose to important congenital disorders, including menigioma disease or the Coffin-Siris syndrome. In this article, we present an exhaustive analysis of the BAF57 molecular and biochemical properties, cellular functions, loss-of-function phenotypes in living organisms and pathological manifestations in cases of human mutations. |
