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