OverviewNCBI Gene

This gene is a classical cadherin from the cadherin superfamily. The encoded protein is a calcium-dependent cell-cell adhesion glycoprotein comprised of five extracellular cadherin repeats, a transmembrane region and a highly conserved cytoplasmic tail. Based on studies in chicken and mouse, this cadherin is thought to play an important role during brain segmentation and neuronal outgrowth. In addition, a role in kidney and muscle development is indicated. Of particular interest are studies showing stable cis-heterodimers of cadherins 2 and 4 in cotransfected cell lines. Previously thought to interact in an exclusively homophilic manner, this is the first evidence of cadherin heterodimerization. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2011]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against CDH4 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 CDH4 as an antibody target. Whether an autoantibody or antibody against CDH4 could matter depends on whether native CDH4 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

CDH4 is annotated at the cell surface, where native CDH4 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 CDH4 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
