OverviewNCBI Gene

This gene encodes a member of the discoidin domain receptor subclass of the receptor tyrosine kinase (RTKs) protein family. RTKs play a key role in the communication of cells with their microenvironment. The encoded protein is a collagen-induced receptor that activates signal transduction pathways involved in cell adhesion, proliferation, and extracellular matrix remodeling. This protein is expressed in numerous cell types and may alos be involved in wound repair and regulate tumor growth and invasiveness. Mutations in this gene are the cause of short limb-hand type spondylometaepiphyseal dysplasia. [provided by RefSeq, Aug 2017]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against DDR2 can act on the native protein depends on physical access: surface and secreted proteins are reachable by circulating antibodies, intracellular proteins usually are not.

Antibody and autoantibody relevanceSeroatlas analysis

Seroatlas reads DDR2 as an antibody target. Whether an autoantibody or antibody against DDR2 could matter depends on whether native DDR2 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

DDR2 is annotated at the cell surface, where native DDR2 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 DDR2 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
