Anti-Chd2 antibodies are used in the immunodetection of the protein chromodomain helicase DNA binding protein 2. In humans, the canonical protein has a reported length of 1828 amino acid residues and a mass of 211.3 kDa. Its subcellular localization is in the nucleus. Alternative splicing is reported to yield 3 different isoforms for this protein. A member of a the SNF2/RAD54 helicase protein family, CHD2 is reported to be a DNA-binding helicase that specifically binds to the promoter of target genes, leading to chromatin remodeling, possibly by promoting deposition of histone H33. Synonyms for this target antigen include EEOC, ATP-dependent helicase CHD2, and DEE94.
