Binds fibroblast growth factor and E-selectin (cell-adhesion lectin on endothelial cells mediating the binding of neutrophils). Golgi and microvilli on the cell surface (PubMed:9099943). Localizes to the postsynaptic Golgi apparatus region, also named Golgi outpost, which shapes dendrite morphology by functioning as sites of acentrosomal microtubule nucleation (By similarity). Widely expressed; found in myeloid cells, fibroblasts, colon carcinoma, endothelioma, teratocarcinoma, lymphoma, myeloma. Fucosylation is essential for binding to E-selectin. Contains sialic acid residues.
