kininogen:C1q binding protein tetramer prekallikrein:kininogen:C1q binding protein tetramer prekallikrein + kininogen:C1q binding protein tetramer -> prekallikrein:kininogen:C1q binding protein tetramer Authored: D'Eustachio, P, 2005-01-20 14:44:36 Prekallikrein (PK) associates specifically with kininogen (HK) on cell surfaces. In vivo, this reaction may occur primarily on the surfaces of endothelial cells in response to platelet activation (Lin et al. 1997; Motta et al. 1998; Mahdi et al. 2003).
