IL-10 transcription is negatively regulated by BAF180, a component of the SWI/SNF chromatin remodeling enzyme
Ontology highlight
ABSTRACT: Several versions of SWI/SNF complexes, BAF and PBAF, have been described based on unique subunit composition. We find that T cell development in the thymus and lymphoid periphery is largely normal in the absence of the PBAF-specific component BAF180. However, BAF180-deficient Th2 cells express high levels of the immunoregulatory cytokine IL-10. BAF180 binds directly to regulatory elements in the Il-10 locus but is replaced by BAF250 BAF complexes in the absence of BAF180, resulting in increased histone acetylation and CBP recruitment to the IL-10 locus. These results demonstrate that BAF180 is a repressor of IL-10 transcription in Th2 cells and suggest that the differential recruitment of different SWI/SNF subtypes can have direct consequences on chromatin structure and gene transcription.
