Background: Angiopoietin-like Protein 2/ANGPTL2

Angiopoietin-like Protein 2 (ANGPTL2), also known as ARP2, is a secreted 56 kDa glycoprotein that contains a coiled coil domain and a fibrinogen like domain (1). ANGPTL2 is one of the eight members of the Angiopoietin like family proteins, which are structurally similar to angiopoietins (2). Mature human ANGPTL2 shares 89% sequence identity with both mouse and rat homologs. ANGPTL2 is widely expressed in many tissues, and its expression is induced by chronic, but not acute hypoxia (3). Elevated level of ANGPTL2 in the serum is also correlated with inflammation and obesity (3). ANGPTL2 has both pro and anti-angiogenic functions (1, 4). It serves as tumor suppressor in ovarian cancer (5), and also promote metastasis in various cancer types, making it potential biomarker for tumor progression (6, 7). ANGPTL2 functions as growth factor to enhance the survival of hematopoietic progenitors, mediated by its coiled-coil domain (8). Receptor of ANGPTL2 is recently identified to be LILRB2, and both the coiled-coil domain and fibrinogen like domain are required for optimal binding (9).
