Background

Angiopoietin-like Protein 2 (ANGPTL2), also known as ARP2 is a secreted 56 kDa glycoprotein that contains a N-terminal coiled coil domain and a C-terminal fibrinogen like domain (1). ANGPTL2 is one of the seven members of the Angiopoietin Like family proteins, which are structurally similar to angiopoietins (2). Within mature mouse ANGPTL2, amino acid 260-493 contains the C-terminal fibrinogen like domain, and this domain shares 99% and 100% sequence identity with human and rat homologs, respectively. 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 also function as growth factor to enhance the survival of hematopoietic progenitors, mediated by its coiled coil domain (8). Receptor of ANGPTL2 is recently identified as LILRB2, and both the coiled coil domain and fibrinogen like domain are required for optimal binding (9).
