OverviewNCBI Gene
This gene encodes a member of the slit family of secreted glycoproteins, which are ligands for the Robo family of immunoglobulin receptors. Slit proteins play highly conserved roles in axon guidance and neuronal migration and may also have functions during other cell migration processes including leukocyte migration. Members of the slit family are characterized by an N-terminal signal peptide, four leucine-rich repeats, nine epidermal growth factor repeats, and a C-terminal cysteine knot. Proteolytic processing of this protein gives rise to an N-terminal fragment that contains the four leucine-rich repeats and five epidermal growth factor repeats and a C-terminal fragment that contains four epidermal growth factor repeats and the cysteine knot. Both full length and cleaved proteins are secreted extracellularly and can function in axon repulsion as well as other specific processes. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2015]

Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads SLIT2 as an antibody target. Whether an autoantibody or antibody against SLIT2 could matter depends on whether native SLIT2 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
SLIT2 is annotated as secreted, so native SLIT2 circulates and is directly accessible to antibodies. Secreted and cell-surface proteins are the autoantibody targets most likely to act like drugs, blocking or depleting the native protein.
Annotation status
The present source text does not explicitly label SLIT2 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
