OverviewNCBI Gene
This gene is a homolog of the Drosophila delta gene. The delta gene family encodes Notch ligands that are characterized by a DSL domain, EGF repeats, and a transmembrane domain. [provided by RefSeq, Jul 2008]

Protein binding partners of DLL4 in the human serome: UniProt-annotated complex subunits plus reported interactors. Each links to its own Seroatlas record.
Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads DLL4 as an antibody target. Whether an autoantibody or antibody against DLL4 could matter depends on whether native DLL4 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
DLL4 is annotated at the cell surface, where native DLL4 is exposed to circulating antibodies and is a prime autoantibody target that could block, deplete, or overstimulate it.
Annotation status
The present source text does not explicitly label DLL4 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
