Function: Kininogens are plasma glycoproteins with a number of functions: (1) as precursor of the active peptide bradykinin they effect smooth muscle contraction, induction of hypotension and increase of vascular permeability. (2) They play a role in blood coagulat
Mechanism: Rats express four types of kininogens: the classical HMW and LMW kininogens produced by alternative splicing of the same gene, and two additional LMW-like kininogens: T-I and T-II.
