Medical Definition of C1 esterase inhibitor

1. An a2-neuraminoglycoprotein that inhibits the enzymatic activity of C1 esterase, the activated first component of complement. A deficiency of this inhibitor results in a lack of inhibition of C1r and C1s leading to uncontrolled activation of the complement cascade and oedema. (05 Mar 2000)
