Anti-CHD4 Antibody Picoband®

Chromodomain-helicase-DNA-binding protein 4 is an enzyme that in humans is encoded by the CHD4 gene. The product of this gene belongs to the SNF2/RAD54 helicase family. It represents the main component of the nucleosome remodeling and deacetylase complex and plays an important role in epigenetic transcriptional repression. Patients with dermatomyositis develop antibodies against this protein. Somatic mutations in this gene are associated with serous endometrial tumors. Alternative splicing results in multiple transcript variants encoding different isoforms.
