Summary: Enables RNA polymerase II cis-regulatory region sequence-specific DNA binding activity and histone binding activity. Involved in gene expression and muscle organ development. Acts upstream of or within DNA damage response and hematopoietic stem cell differentiation. Located in nucleus. Is expressed in several structures, including alimentary system; brain; genitourinary system; respiratory system; and sensory organ. Used to study CHARGE syndrome.

What's a GeneRIF?

Studies results provide initial insight into how Chd2 haploinsufficiency leads to aberrant cortical network function and impaired memory.
Title: Chd2 Is Necessary for Neural Circuit Development and Long-Term Memory.
Chd2 is essential in preventing suppressive chromatin formation for developmentally regulated genes and determines subsequent effects on developmental processes in the undifferentiated state.
Title: Chd2 regulates chromatin for proper gene expression toward differentiation in mouse embryonic stem cells.
inactivation of CHD2 during neurogenesis might contribute to abnormal neurodevelopment
Title: CHD2 is Required for Embryonic Neurogenesis in the Developing Cerebral Cortex.
The data indicated that MyoD determines cell fate and facilitates differentiation- dependent gene expression through Chd2-dependent deposition of H3.3 at myogenic loci prior to differentiation.
Title: Chd2 interacts with H3.3 to determine myogenic cell fate.
Study present evidence that the Chd2 mutant cells are defective in their ability to repair DNA damage induced by ionizing and ultraviolet radiation.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
