OverviewNCBI Gene
The CHD family of proteins is characterized by the presence of chromo (chromatin organization modifier) domains and SNF2-related helicase/ATPase domains. CHD genes alter gene expression possibly by modification of chromatin structure thus altering access of the transcriptional apparatus to its chromosomal DNA template. Alternatively spliced transcript variants encoding distinct isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads CHD2 as an antibody target. Whether an autoantibody or antibody against CHD2 could matter depends on whether native CHD2 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
CHD2 is annotated as predominantly intracellular. Intracellular proteins are common autoantibody markers, becoming visible to the immune system after cell injury or altered processing, but are usually markers of disease rather than direct drivers.
Annotation status
The present source text does not explicitly label CHD2 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
