OverviewNCBI Gene
This gene encodes a protein with two N-terminal Src homology 3 (SH3) domains and 10 tetratricopeptide repeat (TPR) motifs, and is a member of a small gene family. The gene product has been proposed to be an adapter or docking molecule. Mutations in this gene result in autosomal recessive Charcot-Marie-Tooth disease type 4C, a childhood-onset neurodegenerative disease characterized by demyelination of motor and sensory neurons.

Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads SH3TC2 as an antibody target. Whether an autoantibody or antibody against SH3TC2 could matter depends on whether native SH3TC2 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
SH3TC2 is annotated at the cell surface, where native SH3TC2 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 SH3TC2 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
