Amino Acid Sequence
Ala-Tyr-Pro-Gly-Lys-Phe-NH2
一般說明
Ala-Tyr-Pro-Gly-Lys-Phe-NH2(AYPGKF- NH2)是一种选择性,特异性蛋白酶激活受体4(PAR4)激动剂肽。 PAR4是一种G蛋白偶联受体,表达于人血小板表面,参与凝血酶信号通路。 蛋白酶凝血酶对PAR4的切割会刺激受体,并导致血小板聚集的信号传导。
應用
4-雄甾烯-11-β醇-3,17-二酮已用于血小板聚集。
AYPGKF-NH2可用于探测培养系统和血小板中的PAR4信号传导。
生化/生理作用
AYPGK是PAR4受体的配体;结合导致PAR4的激活。 AYPGK通过PAR4刺激体外血小板聚集(EC50=15 μM)。 在用PAR4激动剂处理的人血小板中,AYPGKF刺激血栓烷的产生,血栓烷是一种有效的血小板聚集剂。 此外,AYPGKF介导凝血酶诱导的内皮抑素从大鼠血小板释放。

Ras-related protein 1 (Rap1) is a major convergence point of the platelet-signaling pathways that result in talin-1 binding to the integrin β cytoplasmic domain and consequent integrin activation, platelet aggregation, and effective hemostasis. The nature of the connection between Rap1

Meniscal injury is very common, and injured meniscal tissue has a limited healing ability because of poor vascularity. Platelets contain both pro- and anti-angiogenic factors, which can be released by platelet selective activation. Platelets release a high level of vascular
Anti-apoptotic BCL2L2 increases megakaryocyte proplatelet formation in cultures of human cord blood.
Haematologica, 104(10), 2075-2083 (2019-02-09)
Apoptosis is a recognized limitation to generating large numbers of megakaryocytes in culture. The genes responsible have been rigorously studied in vivo in mice, but are poorly characterized in human culture systems. As CD34-positive (+) cells isolated from human umbilical

Previous reports have indicated that thrombin-induced thromboxane production by human platelets occurs through two types of interaction between thrombin and the platelet surface. One of these interactions is with protease activated receptor(PAR)-1, the first identified thrombin receptor. These studies were

Human platelets display a unique dual receptor system for responding to its primary endogenous activator, α-thrombin. Because of the lack of efficacious antagonists, the field has relied on synthetic peptides and pepducins to describe protease-activated receptor PAR1 and PAR4 signaling.
