General annotation (Comments)

Function	Transcriptional activator which is required for calcium-dependent dendritic growth and branching in cortical neurons. Recruits CREB-binding protein (CREBBP) to nuclear bodies. Component of the CREST-BRG1 complex, a multiprotein complex that regulates promoter activation by orchestrating a calcium-dependent release of a repressor complex and a recruitment of an activator complex. In resting neurons, transcription of the c-FOS promoter is inhibited by BRG1-dependent recruitment of a phospho-RB1-HDAC1 repressor complex. Upon calcium influx, RB1 is dephosphorylated by calcineurin, which leads to release of the repressor complex. At the same time, there is increased recruitment of CREBBP to the promoter by a CREST-dependent mechanism, which leads to transcriptional activation. The CREST-BRG1 complex also binds to the NR2B promoter, and activity-dependent induction of NR2B expression involves a release of HDAC1 and recruitment of CREBBP By similarity.
Subunit structure	Homodimer. Dimerization may be necessary for its function in neuronal dendritic development. Interacts (via C-terminus) with CREBBP (via N-terminus), EP300 and SMARCA4/BRG1. Interacts with the nBAF complex. Association with CREBBP facilitates transcription while the association with SMARCA4/BRG1 suppresses CREST-mediated transcription in resting neurons By similarity.
Subcellular location	Nucleus By similarity. Kinetochore By similarity. Note: Localizes to nuclear bodies. Co-localizes with SGOL1 at kinetochore By similarity.
Tissue specificity	Ubiquitous; with lowest levels in spleen.
Domain	The MFD (multi-functional domain) domain is involved in transcription transactivation, nuclear body targeting and dimerization By similarity.
Sequence similarities	Belongs to the SS18 family.
