OverviewNCBI Gene
The protein encoded by this gene localizes to the primary cilium and to the plasma membrane. The gene functions in centriole migration to the apical membrane and formation of the primary cilium. Multiple transcript variants encoding different isoforms have been found for this gene. Defects in this gene are a cause of Meckel syndrome type 3 (MKS3) and Joubert syndrome type 6 (JBTS6).

InteractionsUniProt · HPA
Protein binding partners of TMEM67 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 TMEM67 as an antibody target. Whether an autoantibody or antibody against TMEM67 could matter depends on whether native TMEM67 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
TMEM67 is annotated at the cell surface, where native TMEM67 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 TMEM67 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
