Is predicted to encode a protein with the following domains: Thrombospondin
type-1 (TSP1) repeat; Immunoglobulin-like fold; Immunoglobulin-like domain superfamily; Immunoglobulin subtype; Immunoglobulin subtype 2; Immunoglobulin I-set domain; Thrombospondin
type-1 (TSP1) repeat superfamily; Immunoglobulin I-set; and Thrombospondin type 1 domain. Is an ortholog of C. elegans
madd-4. In C. elegans,
madd-4 is involved in dorsal/ventral axon guidance and synapse organization.
