Unless otherwise stated all data on this page refer to the human proteins. Gene information is provided for human (Hs), mouse (Mm) and rat (Rn).
The TIE family were initially associated with formation of blood vessels. Endogenous ligands are angiopoietin-1 (ANGPT1, Q15389), angiopoietin-2 (ANGPT2, O15123), and angiopoietin-4 (ANGPT4, Q9Y264). Angiopoietin-2 (ANGPT2, O15123) appears to act as an endogenous antagonist of angiopoietin-1 function.
