| Post Translational Modifications | Proteolytic cleavage by thrombin generates a new N-terminus that functions as a tethered ligand. Also proteolytically cleaved by cathepsin CTSG. Phosphorylated in the C-terminal tail.probably mediating desensitization prior to the uncoupling and internalization of the receptor. |
| Function | High affinity receptor that binds the activated thrombin, leading to calcium release from intracellular stores. The thrombin-activated receptor signaling pathway is mediated through PTX-insensitive G proteins, activation of phospholipase C resulting in the production of 1D-myo-inositol 1,4,5-trisphosphate (InsP3) which binds to InsP3 receptors causing calcium release from the stores. In astrocytes, the calcium released into the cytosol allows the Ca(2+)-dependent release of L-glutamate into the synaptic cleft through BEST1, that targets the neuronal postsynaptic GRIN2A/NMDAR receptor resulting in the synaptic plasticity regulation. May play a role in platelets activation and in vascular development. Mediates up-regulation of pro-inflammatory cytokines, such as MCP-1/CCL2 and IL6, triggered by coagulation factor Xa (F10) in cardiac fibroblasts and umbilical vein endothelial cells. |
