凝血酶Thrombin (Factor IIa)是一種絲氨酸蛋白酶，也是血液凝血級聯反應中的主要效應蛋白酶，顯現出促凝和抗凝的特性。凝血酶是由在凝血酶原復合物中的非活性凝血酶原在Xa因子（FXa）因子的作用下通過蛋白裂解的方式產生
【生理作用】當循環(huán)凝血因子在暴露的血管外組織與組織因子相接觸時，凝血酶會在組織上聚集。凝血酶通過激活血小板，催化纖維蛋白原轉化為纖維蛋白，促進血穩(wěn)定而在血栓性疾病的引發(fā)和傳播上有著核心作用
α-凝血酶（α-Thrombin）是一種高度特異性的絲氨酸蛋白酶，由凝血酶原（prothrombin，II因子）經蛋白水解活化而來。它在凝血過程中起著非常重要的作用，不僅能夠促使纖維蛋白凝塊的產生，還負責提供反饋信號來激活前輔因子：V因子和VIII因子。也可以激活XIII因子和血小板，或者用作血管收縮劑。
在體內，活化的X因子（Factor Xa）切割凝血酶原，釋放出活性肽并將凝血酶切割成具有催化活性的α-凝血酶。α-凝血酶由一條輕鏈（A chain）（Mw ~6,000）和一條重鏈（B chain）（Mw ~31,000）通過二硫鍵連接而成。某些情況下，α-凝血酶會發(fā)生自溶生成β-凝血酶和γ-凝血酶。β-凝血酶由對α-凝血酶A鏈水解并切割含有B鏈糖基化位點的小片段（B1，B2）組合而成。
除了用于凝血研究之外，α-凝血酶還常用來位點特異性切割融合蛋白。基因重組時將凝血酶識別位點插入在目的蛋白與利于后續(xù)純化和/或表達的多肽或者蛋白之間，通過凝血酶切割表達的重組子即可釋放目的蛋白。凝血酶本身可通過親和層析技術快速去除。
作為生物活性物質的凝血酶：是一種在人體抗凝，促凝的凝血級聯反應中有著重要作用的生物活性蛋白。
