General annotation (Comments)

Function	May activate or repress transcription via interactions with sequence specific DNA-binding proteins. Repression may be mediated at least in part by histone deacetylase activity (HDAC activity). Ref.5 Ref.7
Subunit structure	Component of the B-WICH complex, at least composed of SMARCA5/SNF2H, BAZ1B/WSTF, SF3B1, DEK, MYO1C, ERCC6, MYBBP1A and DDX21 By similarity. Binds to and represses JUN and MYB via the leucine zipper regions present in these proteins. Also binds to and represses PPARGC1A: this interaction is abrogated when PPARGC1A is phosphorylated by MAPK1/ERK. Binds to and stimulates transcription by AHR. Binds to KPNA2.
Subcellular location	Nucleus › nucleolus. Cytoplasm. Note: Predominantly nucleolar. Also shuttles between the nucleus and cytoplasm. Nuclear import may be mediated by KPNA2, while export appears to depend partially on XPO1/CRM1. Ref.1 Ref.6
Tissue specificity	Ubiquitously expressed. Ref.1
