    basic FUNCTION
  • actin-dependent regulator of chromatin structure
  • possesses at least two interaction surfaces, one for NR3C1 and SMARCA4 and a second for SMARCC1 and SMARCC2
  • may provide another critical and direct link between nuclear receptors and the BRG1 complex that is required for promoter recruitment and subsequent chromatin remodeling
  • directly interacts with the coactivator groove in the AR ligand-binding domain via its FxxFF motif, thereby selectively activating specific AR-driven promoters
  • likely critical role for SMARCD1 in the coordinated regulation of hepatic circadian clock and energy metabolism in mammals
  • likely key component of the transcriptional control in cardiac progenitors
  • is a critical node integrating the circadian clock and vascular smooth muscle cells (VSMCs) physiological homeostasis
  • EGFR, CALM3 and SMARCD1 play roles in bone and/or fat metabolism
  • is both an activator and a repressor and is enriched at developmental regulators and its chromatin binding coincides with H3K27me3
  • potential role for SMARCD1 in restricting pluripotency and activating lineage pathways by regulating H3K27 methylation
  • SMARCB1, SMARCD1 and SMARCE1 might act as novel pro-senescence factors in both normal and tumor human skin cells
  • regulates the transcription of target genes through the alterations of chromatin structure
  • dietary nutrient-associated impaired expression of SMARCD1 triggers likely cellular senescence and lipid accumulation
  • is required for normal memory, post-development, in adult neurons
  • role of SMARCD1 in establishing proper cognitive functions
  • CELLULAR PROCESS nucleotide, chromatin organization
    nucleotide, transcription
    a component component of the chromatin remodeling complex
    small molecule
  • interacting with FEZ1
  • interacting with TNIP2 (nuclear TNIP2 defines a novel transcriptional coactivator and acts presumably by recruiting a chromatin-remodeling complex to the site of the target gene)
  • interacting with the tetramerization domain of p53
  • CHFR interacts with SMARCA4, SMARCB1, and SMARCD1 of the SWI/SNF-like BAF complex and ubiquitinates them to target for degradation through a proteasome-mediated pathway, and SMARCC1 stabilizes these components by blocking their interaction with CHFR
  • TBX1 interacts with, and probably recruits a specific subunit of, the BAF complex (SMARCD1) as well as histone methylases to activate or enhance transcription, enhancing SMARCD1 occupation at the WNT5A gene and its H3K4 monomethylation status
  • SMARCA4, SMARCB1, and SMARCD1, but not SMARCC1, are the substrates of CHFR for ubiquitination
