ANGPTL7/ Angiopoietin-related proteins are negative regulators of corneal angiogenesis and play an important role in maintaining the patency and transparency of corneal blood vessels. ANGPTL7 is regulated by SP1 transcription and regulates ANGPTL7 levels through the RhoA/ROCK signaling pathway mediating CLAN formation. ANGPTL7/Angiopoietin-related 7 Protein, Canine (HEK293, His) is the recombinant canine-derived ANGPTL7/Angiopoietin-related 7 protein, expressed by HEK293 , with C-His labeled tag.
