Description
Product Characteristics: Protein. The extracellular domain of mouse LYVE-1 (aa 24-228) is fused to the N-terminus of the Fc region of mouse IgG2a. Source: HEK 293 cells. Endotoxin content: <5EU/mg protein (LAL test, Lonza). Lyophilized from 0.2µm-filtered solution in PBS. Purity: >98 % (SDS-PAGE). Lymphatic Vessel Endothelial Hyaluronan (HA) Receptor-1 (LYVE-1) is a 60- kDa type I transmembrane glycoprotein that is a member of the Link Protein superfamily. HA is found in the extracellular matrix of most animal tissues and in body fluids. It modulates cell behavior and functions during tissue remodeling, development, homeostasis, and disease. It is often used as a marker of lymphatic endothelia. LYVE-1 is expressed on both the lumenal and ablumenal surfaces of lymphatic endothelium, and also on hepatic blood sinusoidal endothelia. This expression pattern, combined with studies showing that LYVE-1 can support cellular HA internalization in vitro, may suggest LYVE-1 participation in HA internalization for degradation, or transport of HA from tissues into the lumen of lymphatic vessels. LYVE-1-directed HA localization to lymphatic surfaces might also affect aspects of the immune response or tumor metastases. HA binding to CD44 can still occur in the presence of LYVE-1 in vitro. Therefore, LYVE-1-directed HA localization to lymphatics could provide a substrate for transmigrating CD44+ leukocytes or tumor cells. In addition to hepatic and lymphatic endothelia, some expression of LYVE-1 has been reported on Kupffer cells, the islets of Langerhans, cortical neurons, and renal epithelium.

Target Information: This gene encodes a type I integral membrane glycoprotein. The encoded protein acts as a receptor and binds to both soluble and immobilized hyaluronan. This protein may function in lymphatic hyaluronan transport and have a role in tumor metastasis. [provided by RefSeq, Jul 2008]
