OverviewNCBI Gene
This gene encodes a member of the Cbl family of E3 ubiquitin ligases. Cbl proteins play important roles in cell signaling through the ubiquitination and subsequent downregulation of tyrosine kinases. Expression of this gene may be restricted to epithelial cells, and alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.

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