Binds fibroblast growth factor and E-selectin (cell-adhesion lectin on endothelial cells mediating the binding of neutrophils). Golgi medial cisternae (PubMed:2909545). Localizes to the postsynaptic Golgi apparatus region, also named Golgi outpost, which shapes dendrite morphology by functioning as sites of acentrosomal microtubule nucleation (PubMed:31522887). Widely expressed; found in kidney, pancreatic islets, parathyroid, thyroid, adrenal tissue, brain neurons, astrocytes, adenohypophysis, cultured pheochromocytoma cells. Fucosylation is essential for binding to E-selectin. N-glycosylated. Contains sialic acid residues.
