Other helicases function in processes involving DNA strand separation, including replication, repair, recombination, and transcription. This protein is thought to be involved with cellular proliferation and may play a role in leukemogenesis. Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Jan 2014]. * **UniProt Summary**: Plays an essential role in normal development and survival. Involved in regulation of the expansion or survival of lymphoid cells. Required for de novo or maintenance DNA methylation. May control silencing of the imprinted CDKN1C gene through DNA methylation. May play a role in formation and organization of heterochromatin, implying a functional role in the regulation of transcription and mitosis (By similarity). {ECO:0000250|UniProtKB:Q60848}. |HDA2-3| |SNF2 N| |Helicase C| |pericentric heterochromatin assembly| |maintenance of DNA methylation| |heterochromatin assembly| |methylation-dependent chromatin silencing| |pericentric heterochromatin| |heterochromatin organization| |helicase activity| |chromatin remodeling at centromere| |centromere complex assembly| |chromosome, centromeric region| |chromatin silencing| |chromatin organization involved in negative regulation of transcription| |chromatin organization involved in regulation of transcription| |negative regulation of gene expression, epigenetic| |lymphocyte proliferation| |mononuclear cell proliferation| |leukocyte proliferation| |chromatin assembly| |gene silencing| |chromatin assembly or disassembly| |chromatin remodeling| |DNA packaging| |protein-DNA complex assembly| |regulation of gene expression, epigenetic| |protein-DNA complex subunit organization| |DNA conformation change| |covalent chromatin modification| |lymphocyte activation| |cell division| |cell population proliferation| |chromatin organization| |DNA metabolic process| |cellular protein-containing complex assembly| |leukocyte activation| |chromosome organization| |cell activation| |negative regulation of transcription, DNA-templated| |negative regulation of nucleic acid-templated transcription| |negative regulation of RNA biosynthetic process| |negative regulation of RNA metabolic process| |cell cycle| |negative regulation of cellular macromolecule biosynthetic process| |negative regulation of nucleobase-containing compound metabolic process| |negative regulation of macromolecule biosynthetic process| |ATP binding| |negative regulation of cellular biosynthetic process| |negative regulation of biosynthetic process| |protein-containing complex assembly| |negative regulation of gene expression| |protein-containing complex subunit organization| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp512|Olaparib 4μM R08 exp512]]|-3.22| |[[:results:exp520|Rucaparib 6.5μM R08 exp520]]|-2.35| |[[:results:exp246|UM0011500 10μM R05 exp246]]|-2.15| |[[:results:exp120|Dimethyl-Sulfoxide 1pc R03 exp120]]|1.72| |[[:results:exp226|Cerivastatin 0.15μM R05 exp226]]|1.85| |[[:results:exp228|Demecolcine 0.03μM R05 exp228]]|1.91| |[[:results:exp418|Tunicamycin 0.04μM R07 exp418]]|2.03| |[[:results:exp264|Arsenate 40μM R06 exp264]]|2.32| No correlation found to any other genes in chemogenomics.
