功能： developmental stage:Overexpressed in CD34-positive erythrocyte progenitor cells in acute myeloid leukemia. Down-regulation correlates with hematologic remission following chemotherapy.,function:Helicase that possesses intrinsic ATP-dependent nucleosome-remodeling activity. Complexes containing SMARCA5 are capable of forming ordered nucleosome arrays on chromatin; this may require intact histone H4 tails. Also required for replication of pericentric heterochromatin in S-phase specifically in conjunction with BAZ1A. Probably plays a role in repression of polI dependent transcription of the rDNA locus, through the recruitment of the SIN3/HDAC1 corepressor complex to the rDNA promoter. Essential component of the WICH complex, a chromatin remodeling complex that mobilizes nucleosomes and reconfigures irregular chromatin to a regular nucleosomal array structure. The WICH complex regulates the transcription of various genes, has a role in RNA polymerase I and RNA polymerase III transcription, mediates the histone H2AX phosphorylation at 'Tyr-142', and is involved in the maintenance of chromatin structures during DNA replication processes.,similarity:Belongs to the SNF2/RAD54 helicase family. ISWI subfamily.,similarity:Contains 1 helicase ATP-binding domain.,similarity:Contains 1 helicase C-terminal domain.,similarity:Contains 2 SANT domains.,subunit:Catalytic subunit of the four known chromatin-remodeling complexes: CHRAC, RSF, ACF/WCRF, and WICH. Each complex contains subunits which may regulate the specificity or catalytic activity of SMARCA5. ACF/WCRF contains BAZ1A; CHRAC contains BAZ1A, CHRAC1, and POLE3; RSF contains RSF1; WICH contains BAZ1B/WSTF. SMARCA5 is the catalytic subunit of the NoRC chromatin-remodeling complex, which also contains BAZ2A and of SMARCA5/cohesin/NuRD complexes. The BAZ2A subunit of NoRC also interacts with DNMT1, DNMT3B and HDAC1, which allows NoRC to actively suppress rDNA transcription by a combination of nucleosome remodeling, histone deacetylation, and DNA methylation Component of the B-WICH complex, at least composed of SMARCA5/SNF2H, BAZ1B/WSTF, SF3B1, DEK, MYO1C, ERCC6, MYBBP1A and DDX21. Interacts with MYO1C.,tissue specificity:Ubiquitously expressed.,
