Predicted to enable several functions, including NF-kappaB binding activity; calcium-dependent phospholipid binding activity; and calcium-dependent protein binding activity. Acts upstream of or within Notch signaling pathway. Located in collagen-containing extracellular matrix. Is expressed in several structures, including alimentary system; blood vessel endothelium; central nervous system; chondrocranium cartilage condensation; and chordamesoderm.
