DCBLD2, CLCP1, ESDN, Discoidin, CUB and LCCL domain-containing protein 2, CUB, LCCL and coagulation factor V/VIII-homology domains protein 1, Endothelial and smooth muscle cell-derived neuropilin-like protein

DCBLD2, otherwise known as ESDN (endothelial and smooth muscle cell-derived neuropilin-like molecule) is a novel type-I transmembrane protein with the longest cleavable secretory signal sequence among eukaryotes. It is expressed in various tissues; particularly highly expressed in cultured vascular smooth muscle cells. DCBLD2 is considered to play a role in regulation of vascular cell growth and may have a wide variety of functions in other tissues including the nervous system, like neuropilins.
