OverviewNCBI Gene

This gene encodes an integral membrane protein that contains two N-terminal leucine-rich repeats domains and contains C-terminal regions similar to neurotrophin receptors. The encoded protein may play a role in modulating neurite activity. Alternatively spliced transcript variants encoding the same protein have been described.[provided by RefSeq, Feb 2010]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against SLITRK2 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 SLITRK2 as an antibody target. Whether an autoantibody or antibody against SLITRK2 could matter depends on whether native SLITRK2 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

SLITRK2 is annotated at the cell surface, where native SLITRK2 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 SLITRK2 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
