OverviewNCBI Gene
This gene encodes a member of the UNC13 family. UNC13 proteins bind to phorbol esters and diacylglycerol and play important roles in neurotransmitter release at synapses. Single nucleotide polymorphisms in this gene may be associated with sporadic amyotrophic lateral sclerosis. [provided by RefSeq, Feb 2012]

Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads UNC13A as an antibody target. Whether an autoantibody or antibody against UNC13A could matter depends on whether native UNC13A is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
UNC13A is annotated at the cell surface, where native UNC13A 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 UNC13A as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
