PHYSICAL PROPERTIES

STRUCTURE

motifs/domains	a FS domain found in F-spondins, mindins, M-spondin and amphiF-spondin, with a presence of three disulfide bonds associated with the N- and C-termini of the domain and a highly conserved N-linked glycosylation site
	a reeler, a spondin and six thrombospondin type 1 repeat domains

HOMOLOGY

SUBCELLULAR LOCALIZATION

extracellular

basic FUNCTION	may have a role in the growth and guidance of axons
	promoting factor for cementoblastic differentiation
	attaches to the extracellular matrix and promotes axonal outgrowth
	is a novel protein in osteoarthritis (OA) cartilage, where it may act in situ at lesional areas to activate latent TGF-beta and induce cartilage degradation via pathways that involve production of PGE2
	secreted and extracellular matrix-attached protein that has been implicated in axonal pathfinding during neural development as well as in vascular remodelling in adult tissues
	multi-domain extracellular matrix (ECM) protein and a contact-repellent molecule that directs axon outgrowth and cell migration during development
	cementoblast specific gene, which could promote periodontal ligament cell lines

small molecule

protein	downregulates recruitment to the root side of periodontal tissue via LRP8 and inhibits differentiation of osteoclastic precursors
