Background: Stabilin-2

Stabilin­-2, also known as HARE (Hyaluronic Acid Receptor for Endocytosis) and FEEL­2 (Fasciclin, EGF­-like, laminin type EGF­-like, and Link domain containing scavenger receptor 2), is a type I transmembrane multi­domain protein that is the closest homolog of stabilin­1. It is a scavenger receptor that is expressed on sinusoidal endothelial cells of liver, spleen, and lymph node (1, 2). Its 2439 amino acid (aa) extracellular domain contains seven fasciclin domains, multiple EGF-­like and laminin type EGF-­like domains, and a link domain related to molecules of the TSG­6 superfamily (3). The 72 aa cytoplasmic tail of Stabilin­2 contains a motif that allows the AP2 classical cargo adaptor to direct cargo into clathrin­coated pits (4). Stabilin­2 also mediates the endocytosis of chondroitin and chondroitin sulfate, advanced glycosylation end­product (AGE), collagen N­terminal propeptides and acetylated LDL (4-7). Stabilin-2 has been found to regulate the cancer progression, and high expression of Stabilin-2 was reported to predict poor tumor prognosis in NSCLC (8).
