Functional Description ? help Back to Top
Source	Description
UniProt	Component of a multiprotein complex equivalent of the SWI/SNF complex, an ATP-dependent chromatin-remodeling complex, which is required for the positive and negative regulation of gene expression of a large number of genes. It changes chromatin structure by altering DNA-histone contacts within a nucleosome, leading eventually to a change in nucleosome position, thus facilitating or repressing binding of gene-specific transcription factors. May play an essential role in the transition from the vegetative to the reproductive phase of development. May be a positive regulator of ABA signaling. {ECO:0000269\|PubMed:12140326, ECO:0000269\|PubMed:14682613, ECO:0000269\|PubMed:16055636, ECO:0000269\|PubMed:19033529}.
